If unable to do so or if there is a risk of personal injury stand well clear and call the fire brigade. 3.10 General safety warnings It is important to be aware of the potential hazards associated with the operation of farm machinery. Numerous research studies have shown that the majority of machinery- related accidents occur as the result of human negligence, including taking shortcuts to save time, lack of or improper maintenance, ignoring warnings, failing to read the operator's manual, lack of or improper instruction and failure to follow safety rules. Read and understand this operator manual before using the machine. If any of the instructions appear unclear do not hesitate to contact your McHale dealer. Only competent persons who have read and fully understood this manual are qualified to operate this machine. (See ‘Trained operator criteria’). The owner of this machine is obliged, by law, to ensure that every operator understands all of the functions, controls, working processes and safety warnings, before operating the machine. Safety devices  All safety devices such as guards, protection parts and safety controls must be in place and in fully functioning condition. It is forbidden to operate this machine with defective or incomplete safety devices. WARNING: Fire prevention To reduce risk of fires it is recommended that the machine be kept reasonably clean and free of build-ups of crop, lubricants, etc. Clean the machine regularly ensuring the tractor engine is shut down. WARNING: Do not risk personal injury If a fire is too far advanced, do not try to extinguish it. Avoid smoke inhalation and severe burns. Burning tyres or gas struts can explode unexpectedly.

18 Danger Zone  The ‘Danger Zone’ is the area around the front of the tractor, between the tractor and baler and a minimum of 5 m at the back of the machine to allow for safe bale discharge.  It is the operator’s responsibility to ensure that there is no person in the ‘Danger Zone’ while operating the machine, especially during start up. Before repair or reassembly  Safe lifting gear of sufficient capacity must be used for machine assembly. All chains and slings used must be in good condition. Before operation  Never operate farm machinery while under the influence of drugs or alcohol. The physiological effects of drugs and alcohol impair performance and can lead to operators taking risks or putting others at risk. This includes over-the- counter cold/flu and allergy medications or prescription drugs that are not recommended to be taken whilst driving a car or operating machinery.  The operator must ensure that the manufacturer’s instructions for attaching and detaching the machine are followed. This includes the drawbar attachment, the electric and hydraulic lines, in particular the lighting and brake system.  The operator must ensure that all covers are closed and all safety devices are in operating mode.  The operator must ensure that there is no person in the ‘Danger Zone’. NOTE: ‘Danger Zone’ can vary in size The operator must be aware of the ‘Danger Zone’ which can vary in size, depending on operating conditions, i.e. hilly terrain.

19  Always be familiar with the health and safety requirements that may be in force in the country of use. During operation  While operating this machine on hilly or sloping ground the operator must take extra precautions, in particular as the ‘Danger Zone’ is increased in such conditions.  Precaution must be taken when travelling over sloping or rough ground due to the risk of overturning. Always travel at a speed suitable for the ground conditions.  The operator must ensure that there is a minimum of 4 m clearance between the machine and any obstacle above, in particular electrical high voltage lines.  Never operate the machine with guards or safety devices damaged or missing.  Avoid contact with the knife.  Particular care must be taken, if the machine is left idle for any extended period, to ensure that all sensors and safety features are working correctly.  Never climb onto any part of the machine, while it is in operation. Before travelling on public roads  The owner of this machine is obliged by law to ensure that every operator has a valid driving licence and is familiar with the road traffic regulations relating to the country of use.  Always ensure that the electronic control box and oil supply are switched off.  When parking, both wheels of this machine have to be blocked using the wheel chocks and hand brake (if fitted) should be applied according to the road traffic regulations, relating to the country of use.  Ensure lights are connected and working correctly.  The machine is not suitable for towing at speeds above 40 km/h.  Check that the area around the wheels and especially the brake hubs are clear of build-up of crop material. Performing maintenance  Maintenance and repair work on the machine should always be carried out in accordance with this manual.  Maintenance and repair work exceeding the content of this manual should only be carried out by qualified persons or your McHale dealer. WARNING: Do not carry people or animals on the machine The operator must ensure that no persons or animals are carried on the machine at any time or are hidden under the machine (on the tractor persons are only allowed to sit on the relevant seats).

20  When conducting maintenance work tie long hair behind your head. Do not wear a necktie, necklace, scarf or loose clothing when you work near the machine or moving parts. Rotating machinery parts can entangle loose clothing, long hair or dangling jewellery faster than a victim can react. If these items were to get caught, severe injury could result.  Before working on this machine or altering any setting, the operator must ensure the following: (a) The tractor has definitely stopped moving (b) The hand brake (parking brake) is applied (c) The engine is shut down (d) The ignition key is removed (e) PTO shaft is removed from PTO stub (f) Electronic power supply and control box is disconnected (g) Hydraulic oil supply is switched off (h) Chamber door lock is applied * It is forbidden to open any safety guards or to carry out any work on the machine, unless the above specified precautions have been carried out.  When conducting maintenance work always support the machine properly. Where possible, lower the attachment or implement to the ground before you work on the machine. If it is not possible to lower the machine or attachment to the ground, always securely support the machine or attachment. Do not work under a machine that is solely supported by a jack. Never support the machine with props that may break or crumble under continuous load.  Tyres should be inspected for wear on a regular basis. Tyres should be replaced before wear becomes excessive or after 10 years from the date of manufacture, as indicated on the tyre. Care must be taken when handling tyres. Tyres shall be inflated to the pressures indicated in this manual and on the machine and never over inflated. Tyres shall only be inflated while on the machine or in an appropriate safety cage.  Never disable any electrical safety circuits, tamper with safety devices or carry out any unauthorised modification to the machine.  Replace any electrical or hydraulic devices immediately, at the first sign of malfunction or failure, as these components affect the functionality, sequencing and thus safety of operation. Never use a machine where a malfunction exists! Contact your McHale dealer to achieve a solution. Always think ‘Safety First’!  Avoid heating near pressurised fluid lines, as pressurised lines can be accidentally damaged when heat goes beyond the immediate flame area.  Regular clean down is recommended in order to maintain the machine in a safe and reliable working condition. McHale recommend that the machine be blown down with an air line, as opposed to a pressure washer, due to the dangers involved with pressure washing and to protect the overall paint work on the machine. If, despite our advice, a pressure washer is used then take extreme caution and operate from ground level only. Never climb onto any part of the machine, while pressure washing, due to the fact that all metal surfaces become extremely wet and slippery and always ensure that the tractor has been shut down, with the ignition key removed.

21  Check bearings for early warning signs of wear or damage and replace if necessary. Always be on alert for bearings that are squeaky or noisy despite being well lubricated and bearing housings that are running very hot especially with a burning smell or paint discolouration. Carry out these checks daily, immediately after using the machine, with the tractor shut down and the handbrake applied. During inspection  If on the rare occasion that it is necessary for an inspection to be carried out within the ‘Danger Zone’ while the machine is running (extremely dangerous and not recommended!), there shall be a fully trained and competent second person operating both the tractor and machine controls. The tractor hand brake shall be applied and the electronic control box shall be in manual mode. The machine shall be on level ground with all guards closed. Communication is key. The operator shall inform the inspector before any machine function is activated. The inspector shall remain in the field of vision of the operator at all times and inform the operator of their intended actions. If communication is lost with the operator, or they move within 1.1 m of moving parts or parts that have the potential to move, all tractor power shall be turned off immediately. Guidance for safety of children on farms  All adults working or present on farms are required, by law, to do everything reasonably practical to ensure the safety and health of children and young people on the farm.  Children must be supervised at all times! Remember, farms are not playgrounds!  Store farm machinery with safety and stability in mind. Lower any implements or loaders to the ground and apply the hand brake.  Always exclude children from potentially dangerous areas (they will often get into apparently inaccessible places). Do not allow them in farm yards on busy days. Contractors should always be made aware of the presence of children.  Never leave children alone in a tractor cab as they can interfere with controls and many children have been killed falling from the door or rear window of a tractor.  Children under 16 years of age should never operate power-driven machinery. Keys should be removed from vehicles and controls left in neutral.  Do not allow children to use bales of any description for playing. It is very easy to fall from stacked bales resulting in serious injury, or fall between them leading to suffocation. Make sure there is no evidence of children burrowing under stacked bales.  Children under 16 should never handle chemicals. Always keep them in their correct containers and securely stored out of sight under lock and key.  Keep matches in a safe place.

22 Danger of lightning strike  If there is a risk of lightning in the area, stop all work.  If there is a risk of lightning when travelling, find a safe place to pull over and stop the tractor.  Do not leave the tractor cab or start work until the risk of lightning has passed.

23 4 Specific safety warnings 4.1 Electronic safety warnings  This machine is equipped with electronic parts and components which comply to the EMC directive 2014/30/EU but still may be influenced by electromagnetic transmissions of other apparatus, such as welding machines, etc.  Check electric cables regularly for signs of breakage or wear. If in doubt always replace.  Do not modify any safety circuits (faulty safety circuits will cause risks). 4.2 Hydraulic safety warnings  The maximum pressure in the hydraulic system of this machine should not exceed 210 bar.  Always ensure the system is not under pressure before working on the machine. Oil under pressure can penetrate the skin and cause injury. Beware of pipes under accumulator pressure, depressurise lines by unthreading connections extremely slowly.  Hydraulically actuated devices must be blocked mechanically against movement, before working on the machine.  If any hoses are removed or replaced ensure they are marked and re-installed to the correct position during re-assembly.  Check hoses monthly for signs of leakage or wear. Use a piece of card when checking for leaks. Fine jets of hydraulic fluid can penetrate the skin. Never use your fingers or face to check for leaks. If in doubt always replace. The recommended maximum working time of hoses should not exceed 5 years. Only use exact specification McHale genuine replacement parts.  Do not work on hydraulic systems unless you are qualified to do so. This work should only be carried out by qualified persons or your McHale dealer.

24 4.3 Noise level  The European directive 2003/10/EC directs employers and employees to control the noise level at work. The noise level at field work may differ according to the tractor, ground, crops and other environmental conditions.  In normal conditions, whilst driving the machine, the noise level to the driver’s ear does not exceed 70 dB (A) with the rear screen of the tractor cabin open. The common noise level of the machine and the tractor is primarily influenced by the tractor noise (radio is an additional noise source). It is recommended to operate this machine with closed cabin windows. 4.4 Fire precautions  Be aware that crops are easily inflammable.  Do not smoke or make use of any open fire next to the machine.  A functioning fire extinguisher should always be available on the tractor.  The machine is to be kept clear of oil, grease, crops, string, plastic or any other flammable material at all times.  Do not continue to work with overheated parts, cables or pipes, unless you have identified and eliminated the reason for overheating.  Check bearings for early warning signs of wear or damage and replace if necessary. Always be on alert for bearings that are squeaky or noisy despite being well lubricated and bearing housings that are running very hot especially with a burning smell or paint discolouration.  Clear away any crop or debris built up around brake-hubs several times per day.  Ensure that the bale chamber is emptied of any partially or fully formed bales before the machine is left idle. 4.5 Special safety devices/instructions  When maintenance or repair work has to be carried out on the machine, the hand brake (parking brake) must be applied, engine shut down with ignition key removed. The PTO shaft must be removed from the PTO stub, with the hydraulic and electric power supply disconnected. It is forbidden to open any safety guards or carry out any work on the machine unless the specified precautions have been carried out.  According to safety regulations, the covers of this machine are designed to be opened only by the aid of a special tool and to be closed without a tool. To unlock the covers, the locks should be turned slightly anti-clockwise with a 13 mm spanner or flat blade screwdriver. To lock the covers push the cover towards the chassis until the fasteners lock into place. It is forbidden to operate the machine without the covers or with them open. The owner of the

25 machine is obliged, by law, to ensure that all covers are installed on the machine and are in good functioning condition.  When maintenance or repair work has to be carried out at the open bale chamber, the chamber door lever valve must be in the locked position. Before the chamber door can be closed it has to be unlocked again. (See ‘Chamber door lock’)  Caution should always be taken when feeding in the net roll or making any adjustments to the netter configuration as the netter knife is extremely sharp!  Always use protective gloves when working near sharp knives or edges.

34 4.10 Jacking guidelines Ensure the machine is on flat solid ground and attached to a tractor. Apply the tractor hand brake, switch off the tractor and remove the key, disconnect the hydraulics and PTO. Use wheel chocks on the opposite wheel to secure against unexpected movement. Suitable, well maintained equipment shall be used to raise the machine. Never go under the machine while it is raised off the ground. The jacking points are at the rear of the machine. Only approach the machine with the jack from the rear, to ensure that there is adequate working room. Ensure the jack makes solid contact with the axle below the jacking point decal, before raising the machine off the ground. WARNING: Do not rely solely on a hydraulic jack! Ensure the machine is additionally supported with axle stands or equivalent of suitable capacity. Never support the machine with props that may break or crumble under continuous load.

35 5 Tractor requirements & preparation 5.1 Tractor requirements The minimum recommended size of tractor for operating the machine comfortably depends mainly on the crop condition and the required cut length of the forage. On flat ground McHale recommends a tractor size of approximately 60 kW. On hilly ground or difficult conditions, an additional 10 to 15 kW is advisable. The following items on the tractor are required for attaching to the machine: 1. Low/high drawbar hitch* that is suitable for a vertical load of at least 1,470 kg and a D value of at least 46 kN 2. Two double-acting spools (½” female quick-release) one with float position for the pick-up reel 3. ½” male quick-release for the tank return (Must be free flow to tank) 4. Hydraulic-brake coupling (or two air-brake couplings), if brakes are fitted 5. 12 V / 7-pin socket for lighting 6. 12 V, 20 A socket or battery power cable 7. 1 ⅜”, 6-spline PTO shaft set to 540 rpm (1,000 rpm optional). For North American markets, a 1 ⅜”, 21-spline 1,000 rpm PTO shaft is optional. 8. Suitable location to attach safety chain. The safety chain must be attached in such as way that if the coupling breaks, the hitch or drawbar cannot make contact with the ground. * Depending on country of use 5.2 Control box installation A good power supply is critical for proper machine operation as the electronic control box is the main interface between the operator and the machine. The electric power supply is obtained from the 12 V socket of the tractor. Alternately connect the supplied fused electric power lead to the tractor battery ensuring to route away from sharp edges and hot surfaces. NOTE: Use good quality oil Ensure that the tractor has clean, good quality, hydraulic/universal oil to avoid problems later on. Also, the hydraulic filters on the tractor should be changed regularly, according to the manufacturer’s service instructions. Avoid dirt getting into the hydraulic couplings.

36 5.3 Attaching to drawbar The drawbar is to be attached so that the machine is horizontal to the ground. (See ‘Drawbar adjustment’). Machines are set up for hitching to the tractor drawbar. Once the tractor is attached to the drawbar, attach the PTO shaft. Depending on the country of use a safety chain may also be required. Detach in reverse order of attachment. CAUTION: Electrical power supply Do not use any other electric power supply for the electronic control system, otherwise damage may occur. CAUTION: Tractor drawbar and coupling device must be compatible Check that the tractor drawbar is compatible with the coupling device on the machine. If in doubt, consult your McHale dealer.

37 5.4 Preventing unauthorised use To prevent unauthorised use, McHale recommend using the padlock and the locking device provided. Both items are stored in the tool box on the machine and should be fitted to the drawbar coupling when the machine is not in use. Couplings with holes (Swivel hitch, drawbar eyes or coupling rings)  Place the steel plate/s through the hitch eye from the top, and bottom where provided  Attach the padlock underneath, through either hole in the device  Once the padlock is locked, the machine should be secure Other couplings  Slide the keeper plate to the mid-point of the top of the coupling  Hinge the second plate and rotate upwards until the holes align  Attach the padlock through the hole in the device, as indicated  Once the padlock is locked, the machine should be secure

38 5.5 Attaching ‘break-away’ brake (if fitted) The machine hand brake (if fitted) must be applied when the machine is detached from the tractor. The hand brake handle has a rope fitted to a calibrated ring which must have the other end securely fixed to the tractor, each time the machine is attached to the tractor. If the machine hitch ever becomes detached from the tractor this rope will apply the brakes on the machine. 5.6 Attaching the PTO shaft All mechanical functions are related to the correct PTO speed. Follow the instructions as supplied with the PTO unit for correct assembling of the PTO shaft to the tractor. (See ‘PTO shaft adjustment & maintenance’). Ensure PTO cover guards are prevented from rotating, by securing the chain to the tractor. (if fitted) CAUTION: Ensure the hand brake is released when moving Always ensure that the hand brake has been released before moving the machine on the road or operating in a field. Break-away rope fixed to tractor Hand brake handle WARNING: Ensure PTO guarding is in good condition Never use the machine if the PTO guarding is missing or damaged. Entanglement in rotating drive lines can cause serious injury or death. Always stop the engine and ensure that the driveline has stopped before making connections, adjustments or cleaning out PTO driven equipment. CAUTION: Use correct PTO speed to suit gearbox rating Check the gearbox rating on the machine! The machine gearbox will be rated either for a PTO speed of 540 rpm (standard) or PTO speed of 1,000 rpm (optional). The 540 rpm gearbox should be driven at a PTO speed of 400 - 540 rpm, with a maximum of 610 rpm allowed. The 1,000 rpm gearbox should be driven at a PTO speed of 650 - 900 rpm, with a maximum of 1,000 rpm allowed. Exceeding specified PTO/gearbox speeds is likely to cause damage to machine components.

39 5.7 Making connections to the tractor The following connections to the machine are required for attachment behind the tractor: 1. ½” male quick-release for door open (max. flow 70 l/min) 2. ½” male quick-release for door close (max. flow 70 l/min) 3. ½” male quick-release for pick-up reel up (drop floor / knives up) * 4. ½” male quick-release for pick-up reel down (drop floor / knives down) * 5. ½” female quick-release for return line (must be free flow to tank) 6. Hydraulic-brake coupling (or two air-brake couplings), if brakes are fitted 7. 12 V / 7-pin lighting socket 8. Machine loom to control box 9. 1 ⅜”, 6-spline PTO shaft set to 540 rpm (1,000 rpm optional). For North American markets, a 1 ⅜”, 21-spline 1,000 rpm PTO shaft is optional. * With either the drop floor or the knife diverter valve activated See the following image for possible hosing layout. Ensure that the machine operator is familiar with all tractor connections and fittings. Possible layout of hydraulic hosing and electric looms WARNING: Turn off tractor before connecting hydraulic hosing When connecting hydraulic hosing to the tractor, ensure that the tractor engine is turned off and that the ignition key is removed. Ensure that all hydraulic connections are correctly tightened. 540pm gearbox setting 1,000 rpm gearbox setting 1 2 4 3 8 7 6 5

40 5.8 Connecting the control box The electronic control box must be located inside the tractor cab in the operator’s field of vision and within easy reach of the red emergency stop button. (See ‘Electronic control system’). Secure the control unit in the tractor cab, using the V-brackets and fasteners provided. The male half attaches to the control box and the female half attaches to the tractor cab allowing for quick placement/removal, every time it is used. Ensure that the cable to the machine is not under tension and not near sharp edges, etc. The control box is to be connected to a 12 V, 20 A power supply, using the supplied power lead or the battery power cable. The control box is not waterproof, it must be protected from rain. 5.9 Lighting system The 7-pin plug of the lighting system on the machine must be connected to the 7-pin socket on the tractor. WARNING: Machine must be connected to free flow tank return The machine must be connected to a free flow tank return at all times during its operation, otherwise damage to the machine components may occur. CAUTION: Do not connect the control box to a 24 V power supply Do not attempt to connect the control box to a power supply greater than 12 V, as machine component damage will result. NOTE: Check lighting system before travelling on the road Before travelling on a public road, the operator must ensure that the complete (tractor and machine) lighting system is in a fully functioning condition.

41 6 Machine requirements & preparation 6.1 Net requirements In order for the machine to produce well-shaped bales of excellent density, a top quality net, that is as similar as possible to the specification recommended below, should be used. It is of the utmost importance that the net is used and stored according to the instructions of the net manufacturer. McHale recommend the use of a net roll which meets the following specifications:  Material: High quality, high density polyethylene  Density: Minimum of 10 g/m ± 10%  Elongation: 15% ± 3%  Strength (in direction of wrap): 900 N / 500 mm  Material width (ideal): 1,230 mm (Max. 1,300 mm)  Max. roll weight: 40 kg 6.1.1 Care of the net roll The net roll should be protected from damage and moisture. Do not remove the protective cover until it is ready for use. Net damage can cause undesired netter performance and affect bale weatherability. NOTE: Minimum turns of net recommended For netting silage, a minimum of two layers of net is recommended. When the material is drier, the netting amount should be increased to four or more turns. A general rule to follow is to apply the amount of net that will maintain the bale size. The maximum bale size recommended is 1.68 m diameter for the V6 and 1.90 m diameter for the V8. ENVIRONMENT: Dangerous health effects of burning plastics It is vitally important to observe health and safety rules in order to avoid unnecessary environmental damage or danger to anybody near the machine. This especially applies to the responsible disposal of plastics. Never throw away or burn waste net or plastic. Burning plastics is toxic as they release dioxins and furans. To inhale dioxins or to be exposed to its fumes can cause deadly results. Respect the environment! Always take waste materials to a recycling centre.

42 6.1.2 Care of the netting system Before operating the machine, ensure that the following procedure is followed to ensure improved netter operation:  Clean off rubber and metal feed rollers and check for any tacky material  Once roller cleaning is carried out, ensure to apply talcum powder to the rubber feed roll 6.1.3 Loading & operating the netter system NOTE: Cleaning solvents Never use cleaning agents such as benzene, petrol, turpentine oil or similar cleaning solvents to clean rubber feed roll, otherwise damage may occur! McHale recommend using either of the following:  A cloth soaked in dish washing liquid  Soapy water This warning is displayed when the roll of net runs out or if the net fails to feed into the chamber. The red light beside button 5 will also flash. Press button 5 to restart netting and the warning will disappear once net starts feeding again. CAUTION: Heavy net rolls should be handled by two people Pay attention to the heavy weight of the net roll. It is recommended that full net rolls should be handled by two people. NOTE: Net cannot be fed if the knife is already tripped Net cannot be fed if the knife is already tripped. (Activating the spool valve in the door close direction automatically resets the net knife.) CAUTION: Use protective gloves Use protective gloves for any manual work in this area! Beware of sharp knife edges. WARNING: Always think 'Safety First'! Ensure the PTO is disengaged, the tractor is shut down and ignition key has been removed.

43 The following is the procedure for changing a roll or fitting the first roll: 1. Ensure the PTO is disengaged, the tractor is shut down and ignition key has been removed. Slide the new roll of net onto the net storage space on the platform. NOTE: Ensure that the roll is orientated in the correct direction. 2. Lift the net roll bar upwards until it locks in the raised position. 3. Remove any packaging material and the empty cardboard core of the finished net roll and dispose of responsibly. Move the new net roll from the storage position onto the netter cradle 4. Pull approximately 80 cm of net off the roll. (See CST00869) Spread the net across the rubber feed roller.

44 After the roll is replaced, the tractor and electronic control box is powered back up and the PTO is engaged. Once the net button is pushed, the net feeds into the chamber, netting the bale and the knife trips. The operator then checks that netting is complete and work can continue as normal. 6.1.4 Net layer adjustment setting In an automatic cycle, the netter starts feeding net once the set bale diameter has been reached. The bale is then wrapped with the predetermined net length and the net knife is tripped. It is recommended that a minimum of two (2) layers of net are applied to the bale. Dry conditions and very high densities require up to twice as many layers to ensure a good bale shape. The amount of net applied can be adjusted between 1.1 and 20 layers per bale. 5. Roll the feed roller forward to feed the net into the netter, taking up any slack under the roll. Take care not to trap fingers in between rollers. NOTE: The net should only be fed in to a maximum of 70 cm past the rubber feed roller. 6. Roll the net roll forward from the cradle onto the rollers. Adjust the roll guides equally, allowing 2 to 4 mm clearance each end, so the roll is centred and tightened securely. 7. Pull the net roll bar down onto the roll. The roll of net is now threaded and ready for baling.

45 The net setting can be changed by accessing the machine menu and going into the bale setup. Once the net layers are selected, the setting can be changed using the + or - buttons. The passage of net through the netting unit is monitored. If the net breaks or does not feed, or if the roll of net runs out, then the alarm sounds, the net error symbol is displayed on the control box display and the cycle is halted. Once set, the number of net layers is automatically calculated, regardless of bale diameter or size. In general, automatic mode is used. Manual mode is not normally selected unless there is a machine fault preventing automatic mode from working. In MAN mode, the operator must complete the net feeding and net cutting functions manually. The net is fed in by pushing and holding button 5 until the bale catches the net. When the preset amount of net has been applied, the red light beside button 6 will NOTE: Hay or straw with a high % dry matter needs more net When hay or straw is being baled with high dry matter, more net must be applied. Dry conditions and very high densities require up to twice as many layers to ensure a good bale shape. Adjust net layers up or down using + or - keys Net layer setting (Main screen) (Bale setup menu)

46 flash. The operator then cuts the net by pushing and holding button 6 until the netter knife trips, otherwise net will continuously be applied to the bale. 6.2 Chopper unit knives (V6750/ V8950 only) Knife installation/removal should be carried out in the following way: NOTE: Net cannot be fed if the knife is already tripped. Net cannot be fed if the knife is already tripped. (Activating the spool valve in the door close direction automatically resets the net knife.) CAUTION: Ensure knives are installed correctly Incorrectly installed knives can cause irreparable damage to both the knives and the rotor, leading to serious destruction within the machine! CAUTION: Use protective gloves Use protective gloves for any manual work in this area! The number of knives installed determines the cut length of the material. 1. Ensure the knives are in the up/on position, before beginning. 2. Lower the chopper-unit floor half way. Open the chamber door to the fully-up position. 3. Using the lever valve (A), lock the chamber door in position, by pulling it towards you and then rotating it 90° to the left vertical position, as shown. 4. Shut down the tractor, remove the ignition key, apply the parking brake and prevent any machine movement with wheel chocks. 5. The knife lock/unlock lever (B) is located on the left-hand side of the chopper unit, just behind the pick-up reel. It must be pulled outwards at first, to disengage it from the lock pin (X), then turned 90° downwards, to the unlock position, as shown below. Reverse this procedure to return to the locked position.

47 6. Removal of knives/blanks is the reverse of the following installation procedure. Pay particular attention to all decal warnings and safety advice. Knife Knife blank 7. Rotating the knife lock/unlock lever (B) exposes ‘flats’ on the lock shaft, which allows either knives or knife blanks to be added or removed. Remove old knives with a pair of pliers. 8. A new knife (C) can be installed by inserting it into the back of the slot in the drop floor (D), so it engages with the raised actuator arm (E). Next rotate the knife downwards (F), whilst continuing to hold it towards the back of the slot (D), until the front toothed area looks like it will clear the front end of the slot by 5 -10 mm (G), as shown below. B X Locked ‘closed’ position Unlocked ‘open’ position B X C D F C E

48 9. Now push the knife forwards, continuing to maintain this 5 - 10 mm clearance under the front of the slot. The keyhole slot on the front end of the knife should now guide itself over the ‘flats’ of the lock shaft (H). 10. Continue to push the knife forward until it is in the fully home position, which should leave a gap between the knife and back end of slot of approx. 65 mm (K), with a maximum protrusion of approx. 190 mm (L) (assuming the knife actuators are fully up). The retaining magnets (J) will hold knives in position until the knife- lock shaft is closed. 11. After installing, push the top of each knife forward, in the direction of the arrow (M) as shown, to ensure proper engagement within both the lock shaft and the actuator arm. If the knife moves, then it is not positioned correctly. The correct position is shown at (N). 12. If knives are removed, for any reason, always replace them with knife blanks to prevent crop catching in the ‘open’ slots. These are stored in the knife holster. G 5 - 10 mm H H J approx. K 65 mm 190 mm Max. M M M L N

49 t 13. Installation is simpler, in that they only engage with the lock shaft in front and not with the actuator arm. The knife blank is dropped into a slot, towards the front, again maintaining the 5 - 10 mm gap (G), push forward (P), allowing the keyhole slot to engage with the lock shaft. Then rotate downwards (O) and push forward fully. 14. Always observe the row of knives after installation, they should all be perfectly aligned and at the exact same height. If one or more do not line up, then they are not correctly positioned. Typically, the lowest and furthest forward are correct. 15. Rotating the knife lock/unlock lever (B) back up to 90° onto the lock pin (X), locks all knives/blanks securely. 16. The knives are shown fully down/retracted, with the knife correctly positioned within the actuator arm and the lock shaft in the 'locked' position with the flats vertical (R). Knife tips should protrude 20 - 30 mm maximum (T). WARNING: Turn the levers back into their working position Do not forget to turn the levers (A & B) back into their working position(s), but only after completing all work on the machine, as above. WARNING: Compartment doors panels must be closed while the machine is running - danger of rotating components Always keep the compartment door panels closed while the machine is running because of the danger of rotating components! Take note of all warning decals and ensure that all safety measures and precautions are implemented before attempting to carry out any maintenance work. P P O P R 20 - 30 mm Max. T

50 6.2.1 Knives/blanks storage If knives from the chopper unit are being removed they can be stored on the drive side of the machine (on the chopper unit) in the knife storage area and replaced using blanks. Knives/blanks are secured in the storage area by tightening the clamp lever shown. 6.2.2 Knife sharpening The knives in the chopper unit should be sharpened on the flat side using either a file or a mopping disk. The knife should never become hot while sharpening, otherwise it will lose its tensile strength and cutting edge. Knives/blanks storage Knife blank Knife WARNING: Never use a grinding disk Never use a grinding disk when sharpening the knives. Sharpen this side

51 6.3 Automatic lubrication system The machine is equipped with a fully automatic oiling system which is responsible for lubricating all of the chain systems and a manual greasing system with centralised grease blocks for lubricating all of the roller bearings in the machine. 6.3.1 Automatic oiling system The oil reservoir tank (A) can hold approximately 3 litres of oil and this is enough oil for approximately 12 working hours. It should be kept between the minimum and maximum markings at all times. McHale recommend the use of only top quality chain oil and grease, this will prolong the life of the machine components. On the control box, an alarm is provided to remind the operator to top up the lubrication oil after a preset number of cycles. This counts down from 300 and gives a reminder at zero. It may be reset sooner, if desired, from within the control box sub menus. (See ‘Lube count’) To add oil: 1. Unscrew the top cap and add chain oil to the oil reservoir tank (A), up to the maximum level mark shown. (McHale recommend a good quality high viscosity chain oil with good tack adhesion (ISO 150 - ISO 220)). 2. Replace the cap and tighten fully. Oil reservoir tank A. Oil reservoir tank B. Oil strainer C. Oil filter D. Greasing pump and cartridge (optional) E. Grease cartridge cover (optional) F. Grease cartridge plunger stop (optional) G. Oil pump WARNING: Ensure the tractor is shut down before adding oil Ensure that the tractor engine has been shut down, the key has been removed from the ignition and the brakes have been applied before adding oil. A D G (Optional) E F B C

52 6.3.2 Manual greasing system (standard) The machine is equipped with a manual greasing system, using centralised grease blocks, for lubricating all of the roller bearings in the machine. These instructions cover the main components that must be greased at intervals listed below. Apply one stroke only with a grease gun at each grease point. All other grease points must be greased, as specified. (See ‘Additional greasing’). McHale recommend using a multipurpose, extra high performance grease such as Mobilgrease XHP 222 or equivalent NLGI number 2 grade grease. This will prolong the life of the machine components. Always wear gloves to avoid direct contact with grease, as this may cause skin irritation. NOTE: Oil in the reservoir tank should always be clean The oil in the oil reservoir tank should always be clean, strained and free of any impurities during top-up, as this will ensure proper operation and lubrication. Grease blocks DS Grease blocks NDS The baler’s drive side (DS) and non-drive side (NDS) are greased manually at three centralised grease blocks. Two serve the bearings on the chamber rollers and rotor bearing (and pick-up drive gears on the LHS). These are to be greased after every 1,200 bales approximately. One serves other bearings and bushings via flex pipes and should be greased after every 300 bales approximately. Grease every 300 bales Grease every 1,200 bales

53 6.3.3 Automatic greasing system (optional) The machine is equipped with a fully automatic greasing which is responsible for greasing the roller bearings in the machine baling chamber and oiling of all chain systems. All additional grease points must be greased, as specified. (See ‘Machine maintenance’) A grease cartridge is required after every 1,200 bales approximately. The grease cartridge may be discharged after a few hundred bales but should only be replaced after every 1,200 bales; or at every fourth oil fill. Replacing refill grease cartridge and releasing airlock: McHale recommend using a multipurpose, extra high performance grease such as Mobilgrease XHP 222 or equivalent NLGI number 2 grade grease. This will prolong the life of the machine components. Always wear gloves to avoid direct contact with grease, as this may cause skin irritation. 1. Flip back the the grease plunger stop bracket. Unscrew the cartridge holder from the pump and remove the used cartridge. 2. Pull the plunger all the way back and locate a new refill cartridge. 3. Remove the cap from the plunger end of the refill cartridge. Insert the refill cartridge, as shown, and remove the pull tab seal. 4. Screw the cartridge holder onto the pump, but do not tighten. Only screw the cartridge a few turns, once the threads are engaged. 5. Release the plunger and push the plunger rod all the way back into the cartridge holder.

54 6.3.4 Additional greasing There are several additional grease points, like door hooks, which are not served from the central greasing system and must be greased separately. These points should be greased based on the schedule listed below. 6. Slowly and gently, rotate the cartridge holder open and closed, a quarter turn, several times. Air between the grease pump and the cartridge will escape. When a bead of grease starts to leak out, the cartridge can be tightened fully. 7. Clean off this bead of grease so dust and debris does not stick to it. This dirty grease could get into the grease pump at the next cartridge change, causing a blockage of the grease system. 8. Drop the plunger lock and top up the chain oil. Then reset the lube count on the control box. Grease points DS Grease points NDS Grease every 300 bales Grease every 1,200 bales B

55 Some of the more inaccessible areas are fed from centralised blocks, on either side of the machine, via flex pipes. The rest are individual, but the two lower tension arm rollers require a special procedure to align them with access slots in the chamber walls. Operate the tension arm lock (B) using the following procedure. (See ‘Tension arm lock’) 1. Move the lock lever (B) from the normal working position to the maintenance position, this will cause the stop to move into the bale chamber. 2. Next the tailgate of the machine should be opened fully so that the tension arm passes the stop. 3. In order to release the pressure from the belts the tailgate must now be closed fully. This ensures that the tension arm rests on the stop inside the bale chamber, allowing the belts to hang loose. 4. Close the chamber door lock immediately. (See ‘Chamber door lock’) Release the hydraulic pressure from the tension arm by pressing ‘density release’ (button 9) on the control box until the pressure on the clock falls to zero. The hydraulic and spring pressure is now released allowing the operator to access the grease points through slots in the chamber walls, two on either side. To release the tension arm lock, once tension arm rollers have been greased, the lock lever (B) should be returned to the working position, before opening the tailgate fully to release the stop and then closing the chamber again. The belts are now re-tensioned and the machine can resume as normal. 6.3.5 Oil pump adjustment The oil pump is factory pre-set and under normal circumstances should not require any adjustment. If insufficient oil delivery is noticed on a particular chain, then the pump can be adjusted as follows: The delivery is regulated for pairs of pressure connections, one above the other. Firstly unscrew the black plastic cover on top of the pump, which exposes the five adjusting 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 B B

56 screws. Adjustment to the delivery must be carried out using a slot-head screwdriver (Using a smaller screwdriver may damage the adjustment screw, so use size 8 - 10 minimum).  The delivery is increased by turning the adjustment screw in a clockwise direction and decreased by turning counter clockwise.  One full turn (= 6 clicks) corresponds to 0.015 cc and each click equals 0.0025 cc.  The maximum possible adjustment equals 3 turns or 18 clicks. Oil pump adjustment Once adjustment is complete, screw the black plastic cover back on top of the pump unit. Oil delivery should continue to be monitored and readjusted, if necessary, until desired results are achieved.

57 6.4 Gearbox oil The gearbox is located to the rear of the PTO shaft. Your machine will be fitted with either a 540 rpm or a 1,000 rpm gearbox. Oil quantities and filler ports are different for the different size gearboxes. The 1,000 rpm gearbox has a sight glass for checking the oil level whereas the 540 rpm gearbox has a dipstick on the removable filler breather plug. To drain and add oil to the gearbox, carry out the following procedure: WARNING: Ensure the tractor is shut down before changing oil Ensure that the tractor engine has been shut down, the key has been removed from the ignition and the brakes have been applied before changing oil. The PTO shaft should also be removed. NOTE: Oil must be drained & filled after the first 5 hours of use After the first 5 hours of use, the gearbox oil must be completely drained and filled with SAE 80W/90 grade oil. ENVIRONMENT: Safe disposal of oil Respect the environment! Never spill oil or grease on the ground, never pour them down the drain and never discard them where they can pollute the environment. Always take waste materials to a recycling centre. Gearbox 540 rpm 1. Remove the drain plug (B), located on lower front of gearbox and drain the oil into a suitable container. This is best carried out while the oil is still warm, i.e. soon after use. Replace the drain plug (B), tighten securely and dispose of waste oil responsibly. 2. Remove the breather plug (A) located on top of gearbox towards the rear, using a 17 mm spanner. Add 2 litres of SAE 80W/90 grade oil. 3. Check the oil level using the dipstick on the breather plug (A) and then tighten securely. A B

58 After this, replace the oil once per season or once per 10,000 bales, whichever comes first. 6.5 Tyre inflation pressures Gearbox 1,000 rpm 1. Remove the filler plug (A) using a 24 mm spanner, followed by drain plug (B) using a 12 mm Allen key. Drain the oil into a suitable container. This is best carried out while the oil is still warm, i.e. soon after use. Replace the drain plug (B), tighten securely and dispose of waste oil responsibly. 2. Add 3 litres of SAE 80W/90 grade oil, or until oil becomes visible at the sight glass (C). 3. Replace the filler plug (A) and tighten securely. NOTE: Do not overfill the oil Do not overfill the oil, as this will result in overheating and oil leakage. Overheating oil can also lead to reduced lubrication properties CAUTION: Check the tyre pressure weekly Check the tyres weekly for the pressures outlined in the following table.

59 6.6 Wheel chocks Wheel chocks are provided to secure the machine wheels anytime the machine is to be detached from the tractor, or if the machine is to be stored or parked up. They are located on both the left and right of the back panels, on the rear of the machine. Wheel chocks CAUTION: Unsecure wheel chocks are a hazard for road users! Ensure that the brackets are secure to hold the wheel chocks in place! Wheel chocks coming loose (or falling onto the road), could result in a hazard for third parties. In most cases, both wheel chocks should be used on one wheel, front and back, as shown. The only exception to this is when the machine is parked on hilly ground. In that case, a chock should be used on each wheel, on the downhill side of the slope.

60 6.7 Drawbar & PTO shaft stand usage There are three types of drawbar stands available on the machine, depending on the country of use, one will come as standard: The drawbar stands are to be used every time the machine is disconnected from the tractor. The PTO shaft stand must also be used to support the PTO shaft. Type A - The following applies to the swing down fixed length stand (low hitch):  Transport working position: While using the machine, ensure that the drawbar stand (1) is raised fully with stand pin (3) in the alternate hole position.  Storage position: Ensure that the stand pin (3) is properly placed in the lower slot to prevent the stand from collapse.  Swing down the PTO shaft stand (2) in an upright position in order to support the PTO shaft (4). Type A This is a static swing-down stand (fixed) and is suitable for use on the low drawbar hitch only! Type B This is a hand operated swing-down stand (adjustable screw) and is suitable for raising or lowering the machine for tractors that have static drawbar hitches. This stand type is available on the low drawbar hitch only. This is raised and lowered by means of a crank handle. Type C This is a hand operated fixed stand (adjustable screw) that comes as standard on the high drawbar hitch option. This is raised and lowered by means of a crank handle. CAUTION: All stands must be rested on a solid footing All stands must be rested on a solid footing, on level ground and also supplied wheel chocks must be used. Type A - swing down fixed length stand (low hitch) Transport (working) position Storage position 1 3 1 3

61 Type B - The following applies to swing down screw stand (low hitch):  Similar to type A, except stand pin (3) is in the upper slot, in the transport (working) position. It should be wound up and retracted fully, as shown, before removing the handle. The main difference being, that the drawbar height is now fully adjustable. . Type C - The following applies to the fixed screw down stand (high hitch):  Stand type C is the only type supplied with the high drawbar hitch option and is available as an option on the low drawbar hitch machines.  In order to elevate the drawbar, rotate the jack handle (1) in a clockwise direction as shown below. In order to lower the drawbar, rotate the handle in a counter-clockwise direction.  When the drawbar has been safely connected to the hitch on a high hitch style tractor and the machine weight taken off the stand (by rotating jack handle (1) in a counter-clockwise direction) the lower part of the stand (2) can be retracted quickly by removing the quick-release pin (3) (having first removed the R-clip (4)) and sliding up the lower part of the stand, fully into position. Align the bottom hole and replace the pin (3) followed by R-clip (4).

62  The PTO chain support (5) holds the PTO shaft when disconnected from tractor, in the storage position.  Depending on the height of the windrow being baled, the stand may need to be elevated further, in order to avoid catching crop. This is done by rotating the jack handle (1) in a counter-clockwise direction until it is fully retracted. Type C - fixed screw down stand (high hitch) 3 4 1  2 5

63 6.8 Drawbar adjustment There are two types of drawbar hitch options (high/low drawbar) available on the machine. Depending on the country of use, one will come as standard. This adjustment should be carried out on a level concrete surface, with the tractor hitch aligned such that the exact adjustment can be monitored. Ensure that the tractor engine has been shut down, the ignition key removed and the brakes applied. The machine handbrake must be applied, the main wheels chocked, with the front end of the machine (under the chopper unit) supported on axle stands. The drawbar should be adjusted so that the machine is level and horizontal to the ground when in the working position, see below. To adjust, first remove the safety bolts, then slacken the hinge bolts (C), but do not remove. The hitch eye can be adjusted to different height positions by repositioning bolts (B) in alternating hole positions. It can then be re-adjusted locally by loosening bolts (A & D) to ensure it is level. Once the desired height is achieved, ensure that bolts (A & B) are tightened to a torque value of 750 Nm and the 30 mm top drawbar hinge bolts (C) tightened to a torque value of 1,500 Nm. Tighten bolt (D) and reposition and tighten safety bolts. . WARNING: Adjustment to be completed by qualified persons only This work should only be carried out by qualified persons or your McHale dealer! NOTE: The drawbar bolts must be inspected every two weeks The main drawbar bolts (A & B) along with hinge bolt (C) must be inspected once every two weeks.

64 Tractors typically are either low hitch or high hitch and the drawbar on the machine should be set up accordingly. When changing from a low to a high drawbar set-up, the drawbar is inverted and the hitch eye is adjusted horizontally, in the orientation shown. Once the height of tractor hitch (T) is measured in mm, then allowing for hitch-eye offset (E) the height (H) to the centre of pivot point A can be established (H ≈ T + E). Drawbar configuration Hitch eye A D Safety bolt C B A B

65 The closest value of H can be selected from table above to determine the most suitable bolt hole position for B, depending on whether low or high drawbar set-up. Once adjusted, ensure safety bolt is re-installed and all bolts tightened securely. 6.9 PTO shaft adjustment & maintenance (See ‘Adjusting the PTO shaft to the tractor’) The length of the PTO shaft is suitable for all known tractor conditions. However the PTO shaft must be checked/altered to suit the tractor combination it is being fitted to. Position Low drawbar setting H High drawbar setting H B1 440 830 B2 475 900 B3 510 1000 B4 545 1050 B5 580 1100 CAUTION: Ensure the tractor is shut down Ensure that the tractor engine has been shut down, the key removed and the brakes applied before carrying out the following procedure. WARNING: Measure distance between PTO stub shafts first Never connect a PTO shaft on a new machine/tractor combination without first measuring the shortest distance between PTO stub shafts, otherwise severe damage can occur.

66 First, fit the PTO shaft to the machine and then check if the PTO can be connected to the tractor stub. If not, then the PTO shaft is too long and must be altered. Typically the shortest distance on a trailed machine is when the tractor is turned at the maximum angle from the machine. Operating on very hilly ground can also reduce this further. After measuring carefully, the PTO shaft halves should be cut equally so that the PTO shaft assembly is kept as long as possible, whilst just allowing enough room for its removal. This will ensure that a maximum overlap (ideally 200 mm minimum) is maintained, when extended. Maximum 80° angle of movement should never be exceeded, otherwise permanent damage will result. Min ATTENTION: PTO wide angle joint must never exceed 80 deg. both during operation and when stationary, otherwise permanent damage will result.

67 The recommended quantities of grease in grams for each grease point are shown below. There is also a heavy duty PTO shaft available, as an option. The heavier duty PTO shaft has a longer greasing interval (60 hr) and heavy duty profile tubing. NOTE: Grease point intervals The lower 3 PTO shaft grease points are to be greased at 8 hour intervals. All other grease points are to be serviced at 60 hour intervals. WARNING: Ensure PTO guarding is in good condition Never use the machine if the PTO guarding is missing or damaged. Entanglement in rotating drive line can cause serious injury or death. Always stop the engine and ensure that driveline has stopped before making connections, adjustments or cleaning out PTO driven equipment. Grease at 60 hour intervals Grease at 8 hour intervals

NOTE: Ensure correct machine is selected If the incorrect machine is selected then the baler may not operate as expected. Machine type and serial no. Twine Chopping knives Moisture sensor

71 7.3 Net or twine The standard binding material for this machine is net, with the ability to handle twine as an option if the machine is fitted with a twiner. This operator manual focuses on the use of net only. For operators using twine, there is a separate supplementary twiner manual CLT01169. If the control unit detects that a twiner has been fitted to the machine, then the operator will be able to select either net or twine. To turn on the net option, press menu (button 14) and select machine setup. Then, use the toggle button to select net. NOTE: If a twiner is not fitted to the machine, then by default the twine setting will be crossed out with an X and will not be selectable. In this case, only net can be selected. 7.4 Control box features When the control box is first switched on it displays either ‘McHale V6’ or ‘McHale V8’ along with the machine model and software version number. After a short delay, the working display appears. The working display features an image of the machine, which is surrounded by general working information. Select machine setup menu Twine selected Net selected NOTE: The four softkey buttons are used for multiple functions The four softkey buttons are used for multiple machine functions and menu navigations. Their function changes depending on the current screen and relates to the corresponding symbol directly above each softkey, across the bottom of the screen.

72 The machine has three operating modes; manual (MAN), automatic (AUTO) and semi (SEMI). AUTO is selected by pressing the AUTO/MAN button. The selected mode is displayed in the top right corner of the screen. (AUTO can only be selected if the chamber door is closed.) As the bale is being formed, the diameter increases on the bar graph. At a preset size, a warning beep will sound to indicate that the bale is nearly full. Once the full bale diameter is reached, the operator is warned by a series of beeps. In MAN mode, the operator must complete the net feeding and net cutting functions manually. The net is fed in by pushing and holding button 5 until the bale catches the net. When the preset amount of net has been applied, the red light beside button 6 will flash. The operator then cuts the net by pushing and holding button 6 until the netter knife trips, otherwise net will continuously be applied to the bale. In AUTO mode, net is automatically fed into the chamber and automatically cut when the preset number of layers have been applied to the bale. If the net runs out or fails to feed, the net feed warning is displayed and the red light beside button 5 will flash. Replace the net and press the restart netting button. If the preset diameter has not been reached, pushing net feed (button 5) will start the automatic netting cycle. Pushing and holding net feed (button 5) at any time in AUTO mode will delay the automatic feeding of net, giving the operator a chance to feed in more crop into the chamber if desired. Netting will begin automatically on release of the button. In SEMI mode, when the ‘bale full’ diameter is reached, the operator is warned by a series of beeps. Net does not automatically feed. Press button 5 to start netting. Net will automatically cut when preset number of layers have been applied. SEMI mode is useful on hills where the operator does not want to net the bale until the baler is in a suitable location to eject the netted bale. Using the tractor spool lever, the chamber door can then be opened to eject the bale and at this point a bale is displayed on screen. (See ‘Bale not ejected’). Once the bale has rolled clear and the bale kicker has returned to its normal position, a short beep will sound and the bale on the screen will disappear to indicate when the bale has rolled clear of the chamber.

73 7.4.1 Main working screen The control unit has all vital information displayed on the screen. The main working screen displays the most important information. The 2nd and 3rd working screens display some extra information on the right hand side, which can be accessed by pressing the ‘i’ softkey (button 4). Automatic mode screens The information button can be pressed and held to edit settings displayed in the information bar on the right of the screen. The selected setting will flash in the information bar. The selected bale total can be changed, bale totals can be reset; adjustments to bale density, bale diameter, net layers and net tension can all be made directly on the information bar using the displayed softkeys. 7.4.2 Unblock floor operation When a blockage occurs, the PTO should be stopped immediately. The unblock floor can then be lowered by holding the floor diverter (button 7) and operating the pick-up spool lever in the down direction. The PTO can then be re-engaged and when the blockage is cleared the floor can be raised again by holding the floor button and operating the pick-up spool lever in the up direction. This works the same in MAN or AUTO mode. A sensor on the floor indicates when it has dropped from its working position. The warning below will be shown when the floor is down and the red light beside button 7 flashes. 1st Information screen Bale total Density setting Diameter setting 2nd Information screen 3rd Information screen Supply voltage Net layers setting Knife pressure Live bale diameter Net stretch setting Information bar setting 1 Example 1: Selecting and resetting bale totals Example 2: Adjusting density setting Information bar setting 2

74 7.4.3 Knife operation (V6750/ V8950 only) Standard knife operation The knives can be lowered or raised by holding the knife diverter (button 8) and operating the pick-up spool lever in the tractor. The knives will be raised until the target pressure is reached, at which point the solenoid switches off preventing any further pressure increase. This works the same in MAN or AUTO mode. The knife position is monitored by a sensor which displays an indicator on the main screen if the knives are fully engaged in the chopping position. The hydraulic pressure keeping the knives up can be monitored on the second main working screen. Normal operating pressure, when knives are raised, is limited to 50 bar to protect the knives against foreign objects. Occasionally, if the knives have not been activated for a long time, maximum tractor hydraulic pressure may be needed to raise them. To do this, raise the knives until the pressure reaches normal operating level and stops increasing, then release the knife button and press again while operating tractor hydraulics. The pressure display will be seen to go to the tractor maximum (usually about 180 bar) and the knives will raise. A warning will flash to indicate that knife pressure is too high for baling and the red light beside the knife button will flash. Lower the knives, then raise them again to reset the pressure to normal. The machine must not be used when the knives are in the up position, under full hydraulic pressure, as damage may occur if a foreign object is taken into the pick-up. Selectable knives operation Selectable knives are an optional extra where the chopper unit has two sets of knives, which can be independently controlled. The operator can easily activate either set or both sets of knives. On the machine this is selected by means of a 3-way tap mounted on the machine. Knives in up position Knife pressure Knife pressure is too high warning

75 The selected knife set(s) can be lowered or raised by holding the knife diverter (button 8) and operating the pick-up spool lever in the tractor. The knives will be raised until the target pressure is reached, at which point the solenoid switches off preventing any further pressure increase. This works the same in MAN or AUTO mode. To change the number of chopping knives, lower all knife sets fully, select the desired knives with the tap on the machine, then raise the knives from the control unit. The knife position is monitored by two sensors, one for each set. There are 2 separate indicators which will appear on the screen when either set of knives are fully engaged in the chopping position. 7.4.4 Density release Sometimes the density pressure on the belts may need to be released manually when servicing the machine. This can be done by holding button 9. 7.4.5 Bale shape indicators These are used to tell the operator which side of the bale needs to be filled with crop when baling narrow swathes. Normally, there will be no arrows displayed, just a centre dot which means the bale shape is even. When the bale shape starts to become uneven, the arrows will point in the direction that the operator needs to steer the tractor to fill the smaller side of the bale. The more arrows that appear, the more uneven the bale shape is becoming. A series of beeps accompany the direction arrows so that the operator doesn’t need to watch the screen. A low tone is emitted when the operator needs to steer left and a higher tone for the right. The frequency of the beeps will increase with the number of direction arrows displayed. The bale shape indicators and beeper can be turned on or off in the machine menu. Knife pressure Knives set 1 in up position Knives set 2 in up position Right of chamber needs more crop (drive left) Bale formation is even Left of chamber needs much more crop (drive right)

76 If any arrows are displayed when the chamber is empty and closed, then the rollers may need to be cleaned of any loose material or the sensor zero position may need to be set. (See ‘Machine setup’) The total amount of net used is displayed in metres on the main screen. The amount of net used on each bale is added to the total and displayed on the screen just below the rotating net symbol. This counter can be reset in the machine setup menu. (See ‘Machine setup’) 7.4.7 Lube counter This is a counter to remind the operator to check the chain oil and grease levels. This counts down from 300 bales and when zero is reached the alarm sounds and a lubrication symbol is displayed on the screen. When the alarm sounds, ‘RESET’ will appear above button 2 which should be pressed to reset the counter after oil and grease levels are checked. To reset the alarm early, go into the counters menu and press the reset button. 7.4.8 Voltage monitor The control unit monitors the supply voltage and displays it on the second working screen. If the voltage falls below a safe operating level, this warning screen is displayed. The usual causes are a bad battery, defective charging system on the tractor or loose/corroded connections on the power lead. 7.4.6 Net metres

78 Bale setup This menu allows the user to adjust settings in relation to bale formation. The toggle key (button 3) can be used to scroll between each setting, for the current profile. When the arrow is beside the required setting then the + and - softkeys (buttons 1 & 2) can be used to increase/ decrease the value. Press ‘ESC’ (button 4) to return to the main menu. Bale profile There are 5 bale profiles: A, B, C, D and E. When the arrow is beside the bale profile, then the + and - softkeys (buttons 1 & 2) can be used to select a different profile. The current bale profile is displayed on the main screen. Each bale profile will retain its own settings for:  Core diameter  Bale diameter  Core density  Bale density  Net layers  Net stretch The settings for each profile can vary so that the machine can easily be changed to work with different crops without needing to change a lot of settings. By default, the ‘A’ profile is for maximum density heavy bales, ranging through to ‘E’, which is for minimum density light bales. However, these profiles can be adjusted to suit individual requirements. Core diameter The core diameter can be set from 60 - 150 cm. This adjusts the maximum size of the centre bale core. Bale diameter The bale diameter can be adjusted from 60 - 168 cm on the V6740/ V6750 and from 60 - 190 cm on the V8940/ V8950. The bale diameter setting is also displayed on the information bar on the right hand side of the first main working screen. There is also a vertical bar graph which shows progress as the bale is being made. Core density The core density can be set from 0 - 10. This sets the density for the core diameter setting, then the bale density setting is used for the remainder of the bale formation.

79 Machine setup This menu allows the user to adjust settings in relation to the machine setup. The toggle key (button 3) can be used to scroll between each setting. When the arrow is beside the required setting then the + and - keys or the left and right arrows (buttons 1 & 2) can be used to increase/decrease/change the value. Press ‘ESC’ (button 4) to return to the main menu. Bale density The density can be set from 0 - 10. Normally a maximum of 8 is adequate to produce good dense bales. A higher setting may be required in wet crop conditions. The selected value is displayed as shown on the main screen. Net layers The amount of net applied to the bale can be adjusted from 1.1 - 20 layers per bale. The amount of net is automatically adjusted for different bale diameters. The selected amount of layers are displayed on the second working screen. (See ‘Main working screen’) Net stretch This setting sets the stretch on the net applied to each bale, depending on the option selected. The setting ranges from 1 (min) to 10 (max). McHale recommends a net stretch setting of 5 or less for drier materials. Net or twine Select net or twine. Diameter correction This is used to increase/decrease overall bale size to achieve a desired bale diameter. It can be set to +/- 20 cm.

80 Net delay This is used to set the time delay between the bale full alarm sounding and the net actually feeding into the chamber. Some operators prefer a longer time delay to ensure adequate warning when baling at higher speeds. Net metres This is used to reset the net metres total. Press ‘RESET’ (button 1). Press  (button 3) to confirm the reset. (See ‘Net metres’) Pre-warning beep This is a single warning beep to indicate when the bale is nearly full. The setting is a percentage of the selected bale size. Set to 99% if this function is not desired. Bale shape indicator This is used to turn on/off the bale shape indicators and beeps. (See ‘Bale shape indicators’) On () = Bale shape indicators are shown on the screen but no beeps are active. Off () = No bale shape indicators or beeps are active. Beep () = Bale shape indicators are shown on the screen and the beeps are active. Bale shape indicator zero This is used to set the centre position of the bale shape indicator sensor. Normally, this is only required with a new machine or when the sensor is replaced. To set the zero position, make sure the chamber is fully closed with no crop in the chamber, then select the bale shape indicator zero setting and press ‘RESET’ (button 1). Press  (button 3) to confirm the reset. Measurement units Depending on operator preference, either metric or imperial units can be selected. Knife pressure This sets the target knife pressure and is adjustable between 1 and 10 (32.5-55 bar). The default setting is 6 (45 bar). ‘Knife pressure too high’ warning is shown if the knife pressure exceeds 65 bar. Additive This feature is used to activate/de-activate an additive applicator. When this setting is on, the additive applicator output is automatically controlled. It automatically turns off to minimise additive wastage when no crop is feeding in during netting or while the chamber is open. Turning this setting off disables the additive output for baling crops that do not require additive.

81 7.4.10 Counters This menu allows the user to manage bale and lube counters. The toggle key (button 3) can be used to scroll between each counter. Press enter (button 2) to select a new subtotal. Press ‘ESC’ (button 4) to return to the main menu. Subtotals Press softkey 1 to enter the selected subtotal. Subtotals can be adjusted or reset. Press the + and - keys to adjust the selected subtotal. Subtotal reset To reset a subtotal press softkey 1, followed by the  key to confirm or  key to cancel Lube count The lube count is after bale sub total J and has an oil can symbol. It is an alarm that activates every 300 bales to remind the operator to check oil levels and to grease the machine. The remaining bale count before the alarm will sound is shown. It can be reset in the same way as the subtotals above or from the main screen once the alarm sounds. (See ‘Lube counter’) Grand total The bale grand total cannot be reset and has no letter or symbol displayed.

87 8 Road traffic safety & operation 8.1 Before travelling on any public roadway The following should be inspected every time, before travelling on a public road:  Ensure that the tyres are set to the correct pressure as per safety decals and according to the specifications. (See ‘Tyre specifications*’)  Ensure that all doors are securely closed and fastened, ensuring that primary and secondary catches are fully engaged, these should be kept clear of foreign objects to ensure proper and trouble free operation.  The bale forming chamber should be emptied.  The machine must be safely cleared of all loose forage. To carry this out, firstly turn off the tractor and fully isolate the machine by disconnecting all of the connections to the tractor unit.  The PTO shaft must be fixed safely to the tractor PTO stub shaft.  The lighting system of the machine must be connected to the tractor and must be in a fully functioning condition.  The electronic control box must be switched off or disconnected from the power supply. (See ‘Electronic control system’)  Attention must be paid to the maximum travel speed limit (40 km/h).  The brake system (hydraulic or pressurised air) of the machine, if fitted, must be connected to the tractor. Do not travel, with air brakes, until the required pressure is shown on the indicator of the tractor panel.  Ensure that all the national road traffic regulations relating to the country are fulfilled i.e. the use of safety chains is mandatory in EU countries when air brakes are not installed. The safety chain must be attached in such a way that if the coupling breaks, the hitch or drawbar cannot make contact with the ground.  Lift the pick-up reel completely and close the lever on the hydraulic line (if fitted). The hydraulic supply must be turned off and protected from accidental activation by disconnecting the hydraulic feed line. Support all loose lines in a safe manner. CAUTION: Complete a full inspection before travelling on the road Ensure that a full inspection is completed every time before attempting to go on to a public roadway, always think and practice safety!

88  Check that the area around the wheels and especially the brake hubs are clear of build-up of crop material.  The pick-up guide wheels must be fixed in the road transport position and the drawbar/PTO stands secured in a working position. (See ‘Drawbar & PTO shaft stand usage’) Pick-up wheels in the transport position 8.2 ‘Break-away’ brake (if fitted) The machine hand brake (if fitted) must be applied when the machine is detached from the tractor. The hand brake handle has a rope fitted to a calibrated ring which must have the other end securely fixed to the tractor, each time the machine is attached to the tractor. If the machine hitch ever becomes detached from the tractor this rope will apply the brakes on the machine. CAUTION: Ensure the hand brake is released when moving Always ensure that the hand brake has been released before moving the machine on the road or operating in a field. Break-away rope fixed to tractor Hand brake handle Break-away rope Break-away rope

89 9 Field operation & machine adjustments 9.1 Break-in period McHale recommends a break-in period of approximately the first 50 bales or until the paint within the machine has lost its shine. During this break-in period, the sides of the bales may appear untidy, but once the side-walls have been polished smooth, then bale sides should look neater. After the initial break-in period the tension of all the chains on the machine should be checked and adjusted, as required (See ‘Chain adjustments’). Ensure that all grease points are adequately greased to prevent rapid wear of components. 9.2 Swath preparation An optimum baler performance of the machine requires a good swath preparation in advance. The optimum swath width is 1.5 m. In the case where narrower swaths are unavoidable, it is recommended that the swath be periodically directed 15 - 20 m to the right-hand side and also the same distance to the left-hand side of the pick-up as the baler is driven over the swath. Collect the material into one side of the pick-up for 6 - 8 seconds. Then cross over the windrow and collect material for the same duration. Reduce the length of time for heavy windrows and increase for lighter windrows. Continuous weaving is not recommended as this will result in excessive material being placed towards the centre of the bale. In the case of wider swaths, i.e. >1.5 m; this size of windrow should be avoided, as in this case a greater amount of material will continue to be fed to the outside of the baler. As a result, a greater amount of material will be fed to the outer edges of the bale than to the centre. This will result in concave-shaped bales. NOTE: Swath width is the most important factor in proper bale formation A 1.5 m swath width provides optimum material flow into the bale chamber for even bale formation. A swath width greater or less than 1.5 m will lead to increased bale deformation.

90 Swath widths - correct & incorrect 9.3 Pick-up reel height adjustment Before working in the field secure the pick-up guide wheels, in their operating position, as shown. Use the appropriate hole in the adjusting bar so that the pick-up is balanced and at the optimum working height with the pick-up tines being 2 cm above the ground. Pick-up reel height adjustment NOTE: Ensure the spool control lever is in the float position When baling with this machine ensure that the control lever for the spool operating the pick-up reel height adjustment is in the float position. If the lever is not in the float position then the reel will be fixed in a set position and will be unable to follow the ground contour. NOTE: Wear and tear of pick-up tines Working with the pick-up tines set too low will leave them susceptible to breakage and rapid wear! 2 cm

91 9.4 Crop roller adjustment The function of the crop roller and fingers is to hold down and spread out the baling material in order to achieve a smooth crop flow into the pick-up unit. The crop roller height should be adjusted, by engaging the chain links in the keyhole slots, so that the stops do not rest on the rubber bumpers as shown. Once this initial height is set, it is then self adjusting depending on crop conditions. Ensure linch pins are used to secure chain links together. Once adjusted, the crop roller should run along the top of the swath. In lighter conditions it should be adjusted as low as possible, but still ensure that the stops do not rest on the rubber bumpers. 9.5 Unblocking system The machine is equipped with an unblock system. In the case of a blockage in the feeding channel, the PTO overload clutch will disengage and a loud clicking noise will be heard. Once this sound is heard, immediately turn off the tractor PTO. The channel floor can then be lowered by holding the floor diverter (button 7) and operating the pick-up spool lever in the down direction. Then restart the tractor PTO at a slow speed, increasing speed slowly up to normal working speed. Any lumps of material can now be easily transported into the bale chamber. When the blockage is cleared the floor can be raised again by holding the floor button and operating the pick-up spool lever in the up direction. This works the same in MAN or AUTO mode. (See ‘Unblock floor operation’). Baling can then resume as normal. Crop roller adjustment chain Crop roller stops 20 mm

92 Unblock mode, knives retracted and channel floor lowered 9.6 Chopping system (V6750/ V8950 only) The machine is equipped with a 15 (or 25) knife chopping system for fine cutting. If a coarser chop is required, some of the knives can be removed. (See ‘Chopper unit knives (V6750/ V8950 only)’). The knives can be raised or lowered by holding the knife diverter (button 8) and operating the pick-up spool lever in the tractor, in the up/down direction. It is recommended to switch the chopping device off when baling very dry material. In order to protect the chopping device against overload and damage, the knives are hydraulically protected. If they become overloaded or if a foreign object passes through the rotor and puts undue pressure on the knives, they are able to momentarily retract from the position they are in, to let the material which is causing the overload, to pass into the baler. WARNING: Never go near the pick-up reel, while the reel is still rotating and the tractor is running! Never attempt to go near the pick-up reel while the reel is still rotating and the tractor is running. In the rare case that the reel cannot be unblocked using the procedure above, then the pick-up reel will require manual unblocking, by removing the excess blocked material. To do this safely ensure the PTO is disengaged, tractor shut down, key removed and that all parts have stopped rotating. Also ensure machinery can’t roll by parking machinery on level ground with the brakes applied and wheels chocked. Remove excess material carefully. Always wear protective clothing and gloves, beware of sharp edges!

93 9.7 Selectable knives (V6750/ V8950 only) Selectable knives are available as an option on the machine. The operator can select between 0, 7, 8 or 15 knives (0, 12, 13, or 25 with 25 knife option), by turning the tap on the right-hand side of the chopper unit. The knives must be fully down, before selecting the desired set of knives. (See ‘Knife operation (V6750/ V8950 only)’) 9.8 Knife pressure monitoring (V6750/ V8950 only) The knife position and pressure display, as shown below, is used to indicate whether the knives are in the ‘up’ or ‘down’ position and the pressure applied to the knife operating rams. (See ‘Standard knife operation’) When the knives are being switched on, the pressure will increase to and stop at the normal working pressure of 35 - 60 bar, which is displayed on the screen. The knife sensor symbol should also appear on the screen to indicate that the knives are fully raised into the chopping position. (On machines with the selectable knife option, a separate indicator is displayed for each set of knives.) NOTE: Keep the knife slots clear of material To keep the knife slots clear of material, it is recommended to switch the knives on and off several times daily. (See ‘Knife operation (V6750/ V8950 only)’) Selectable knives Selectable knives tap Knife pressure

94 Knife pressure too high warning A warning will always be shown when the knife pressure is above working pressure. Lower the knives, then raise again to reset to the normal working pressure. 9.9 Netting system In an automatic cycle the control box emits a single beep when the bale reaches 90% (adjustable) of the set diameter. Further to this when the bale diameter reaches 95% of the diameter the moving roller under the netter unit is triggered and the roller moves to it’s inward or netting position. The box will then emit a series of beeps when the bale has reached it’s predetermined diameter, this alerts the operator that netting is about to start. Note: The operator must stop the forward movement of the tractor at once! Next a continuous beep informs the operator that the netting has started. After the preset number of net layers are applied to the bale, the net is cut. The tailgate can then be opened to eject the bale from the bale chamber, this will also reset the netter knife and the moving roller. Once the bale is ejected the tailgate can then be closed and once the tailgate is fully closed a single beep will inform the operator that the door locks are engaged and baling can resume. 9.10 Bale density gauge The bale density gauge is used to indicate the pressure applied to the belt tension rams (on the small side). When the tailgate is closed, and no material in the baling chamber, the pressure shown on the gauge is known as ‘starting pressure’. This pressure will then increase due to the oil in the cylinders being forced through the density valve as material begins to fill up the baling chamber. The density pressure is irrelevant for approximately the first 600 mm of bale formation, as the density is regulated by the tension springs. The density will then rise to the core density setting and after that the needle should rise to the set bale density and remain there until the bale is complete. Pressure should never go above 210 bar, if it does consult your McHale dealer. Crop type and bale density will also affect the net tension on the finished bale. WARNING: Do not bale if the knife pressure is too high! Do not bale if the knife pressure is too high as machine damage will occur!

95 9.11 Setting the bale density The bale density gauge is divided up into increments of 20 bar per increment and has a yellow zone, green zone and a red zone, as a quick reference during machine operation. When baling drier materials such as straw or hay McHale recommend setting the bale density pressure between 70 and 110 bar pressure (setting 4 - 5). When baling wetter materials, such as grass for silage, a pressure of between 110 and 160 bar pressure is recommended (setting 7 - 8). The bale density can be controlled from the control box. The density can be set from 1 - 10. Normally a maximum of 160 bar is adequate to produce good dense bales. A higher setting may be required in wet crop conditions. The selected density setting is displayed on the main screen. 9.12 Net tension gauge The net tension gauge is used to indicate the pressure being generated by the tension on the net during application, depending on the 'net stretch' setting on the control box. The pressure is determined by the control unit, depending on the net tension setting. If there is 0 bar pressure during netting, it would indicate a fault and in this case first check the oil level in the tension pump. (See ‘Net tension pump’). In general, higher tension settings will result in much superior bale shape and presentation, but this depends firstly on the quality of net being used, in that too high a setting will cause lower quality net to break during application or break when the net is on the finished bale. And further, the amount of net being applied will affect the max net tension setting that can be used, in that more layers will allow for a higher overall net tension, as there is more net available to hold the bale together. McHale recommends a net stretch setting of 5 or less for drier materials, when set to a high bale density. (See ‘Net stretch’) CAUTION: Bale density pressure should not go above 210 bar The bale density pressure should never be adjusted above 210 bar pressure. If 230 bar is exceeded, damage to the machine components may result.

96 9.13 Chamber door lock The chamber door lock should be used at all times that the operator may wish to enter the chamber in order to change the cutter knives for example. The lock (A) is located on the front right hand side of the platform, at the front of the machine. See below for the safety decal and location of the chamber door lock valve. The lock works by way of a hydraulic on/off valve, while locked the valve is in the ‘off’ (vertical) position and the hydraulic rams will remain locked open, securing the door in a fixed position. WARNING: The operator must be aware of all related warnings, safety decals and dangers The operator must be aware of all related warnings, safety decals and dangers before attempting to carry out any work or maintenance from within the baling chamber. (See ‘Chopper unit knives (V6750/ V8950 only)’) To lock, pull lever (A) forwards and rotate down 90°, to the left vertical position.

97 9.14 Tension arm lock The tension arm lock is provided so that the hydraulic and spring pressure can be released from the belts when clearing a blockage within the machine or carrying out specific maintenance operations. (See the following decal CST00689) Operate the tension arm lock, using the following procedure. In order to move lever ‘B’ from one position to another the spring-loaded plunger must be retracted. 1. Move the lock lever ‘B’ from the normal working position to the maintenance position, this will cause the stop to move into the bale chamber. 2. Next the chamber door of the machine should be opened fully so that the tension arm passes the stop. 3. In order to release the pressure from the belts the tailgate must now be closed approximately half way so that the tension arm rests on the stop inside the bale chamber, allowing the belts to hang loose. 4. Close the chamber door lock ‘A’ immediately. Working position Maintenance position B B Working position Maintenance position CAUTION: Close the chamber door lock first Ensure the chamber door lock is engaged before carrying out any work inside the chamber or under the tailgate.

98 Release the hydraulic pressure from the tension arm by pressing the density release (button 9) on the control box until the pressure on the clock falls to zero before carrying out any work inside the chamber or under the tailgate. The hydraulic and spring pressure is now released allowing the operator to clear any blockage inside the chamber or carry out specific maintenance operations. In order to grease the bottom two tension arm rollers the tailgate should be closed completely before applying the tailgate lock. The lower roller grease points are now accessible through slots in the chamber walls, two on either side. To release the tension arm lock, once work has been completed inside the chamber, the lock lever ‘B’ should be returned to the working position, before opening the tailgate fully to release the stop and then closing the chamber again. The belts are now re- tensioned and the machine can resume as normal. 9.15 Brake overview (if brakes fitted) The machine comes with either hydraulic or air brakes. The machine is fitted with a hand brake which must be applied when the machine is detached from the tractor. This also serves as a ‘break-away’ brake, when the actuation cord is connected to the tractor. Always obey local road regulations! 9.15.1 Hand brake The machine is equipped with a manual parking brake (hand brake). 9.15.2 Air brakes The machine is equipped with a dual-line air brake system. There are two hoses that must be attached to the tractor for the air brake system to function:  The yellow hose is the service line which controls the rate of braking of the machine.  The red hose is the emergency line, which if disconnected applies the brakes on the machine. Pull the lever to activate the brake. The brake performance increases as you pull the brake (using a normal pulling force), reaching a maximum when the lever stops. The brake performance is at it’s best when the cables are adjusted correctly, all moving parts are lubricated and the teeth on the ratchet and pawl are in good condition. If the teeth on the ratchet or pawl become worn or damaged, they must be replaced immediately.

99 Connection with the tractor To connect, attach the yellow hose coupling first, followed by the red hose. To disconnect, remove the red hose coupling first, followed by the yellow hose. It is important that the above sequence is followed, as the red hose (emergency line) should never be connected on its own. Once the hoses have been disconnected from the tractor, the braking system of the machine is active. The parking brake should also be used to ensure stability of the machine, once disconnected from the tractor. Performance of the brake chamber actuators The brake chamber actuator movement activates or deactivates the drum brakes. If the push rods of the brake chamber actuators bottom out, the brake performance may fail completely. Possible causes are damaged or worn brake shoes and/or defective joints or improper adjustment. Moving the machine with a tractor (without an air brake system) The machine can be moved by a tractor, without an air brake system, even though the air reservoir is full and the hoses are not connected. Locate the air reservoir tank either on the side of the machine or under the platform. Pull the ring underneath which releases the air and hold until all the air has escaped. The tractor can now move the machine once the hand brake has been released. CAUTION: The machine and tractor must be connected first This procedure is only allowed when the machine is attached to a tractor first. By draining the air, the service air brake line will no longer operate. This procedure should be used for emergency purposes only to move a machine around in a yard on a level surface. The machine should never be operated in such a condition or moved on hilly terrain.

100 Maintaining and servicing A maintenance service in a professional workshop is necessary when:  The brake performance is reducing continuously and/or  The brakes squeal or grate heavily when activating the foot brake. 9.15.3 Hydraulic brakes (optional) The machine is equipped with hydraulic drum brakes, using single-line activation. Connection with the tractor Connect the female hydraulic brake hose to the tractor after shutting down the engine. The tractor may have a ‘pressure release’ function, allowing connection to the machine brake hose while the engine is running. The brake is activated by pushing the foot brake pedals in the tractor cabin. For that reason, the brake can only work when the hydraulic hose is connected to the tractor properly and the tractor engine is running. Performance of the brake chamber cylinders The brake chamber cylinders activate or deactivate the drum brakes. If the pistons of the brake chamber cylinders bottom out, the brake performance may fail completely. Possible causes are damaged or worn brake shoes and/or defective joints or improper adjustment. Maintaining and servicing A maintenance service in a professional workshop is necessary when:  The brake performance is reducing continuously and/or  The brakes squeal or grate heavily when activating the foot brake. WARNING: Must be qualified to work on the brake drums This work should only be carried out by qualified persons or your McHale dealer, who are familiar with braking systems.
