Safe Operation Practices for

Riding Rotary Lawn Mowers Read and understand the contents of this manual before operating the machine. The safety alert symbol (Figure 2) is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. The following instructions are from the CEN standard EN 836:1997. This product is capable of amputating hands and feet and of throwing objects. Always follow all safety instructions to avoid serious injury or death. Training • Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. • Never allow children or people unfamiliar with these instructions to use the lawn mower. Local regulations can restrict the age of the operator. • Never mow while people, especially children, or pets are nearby. • Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property. • Do not carry passengers. • All drivers should seek and obtain professional and practical instruction. Such instruction should emphasize: – the need for care and concentration when working with ride-on machines; – control of a ride-on machine sliding on a slope will not be regained by the application of the brake. The main reasons for loss of control are: ◊ insufficient wheel grip; ◊ being driven too fast; ◊ inadequate braking; ◊ the type of machine is unsuitable for its task; ◊ lack of awareness of the effect of ground conditions, especially slopes; ◊ incorrect hitching and load distribution. Preparation • While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals. • Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine. • Warning—Fuel is highly flammable. – Store fuel in containers specifically designed for this purpose. – Refuel outdoors only and do not smoke while refuelling. – Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel while the engine is running or when the engine is hot. – If fuel is spilled, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated. – Replace all fuel tanks and container caps securely. • Replace faulty silencers. • Before using, always visually inspect to see that the blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance. • On multi-bladed machines, take care as rotating one blade can cause other blades to rotate. Operation • Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. • Mow only in daylight or in good artificial light. • Before attempting to start the engine, disengage all blade attachment clutches and shift into neutral. • Do not use on slopes of more than – 5° when mowing on side hills; – 10° when mowing uphill; – 15° when mowing downhill. • Remember there is no such thing as a safe slope. Travel on grass slopes requires particular care. To guard against overturning: – do not stop or start suddenly when going up or downhill; – engage clutch slowly, always keep machine in gear, especially when travelling downhill; – machine speeds should be kept low on slopes and during tight turns; 4

stay alert for humps and hollows and other

hidden hazards; – never mow across the face of the slope, unless the lawn mower is designed for this purpose. • Use care when pulling loads or using heavy equipment. – Use only approved drawbar hitch points. – Limit loads to those you can safely control. – Do not turn sharply. Use care when reversing. – Use counterweight(s) or wheel weights when suggested in the instruction handbook. • Watch out for traffic when crossing or near roadways. • Stop the blades rotating before crossing surfaces other than grass. • When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while in operation. • Never operate the machine with damaged guards or without safety protective devices in place. • Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed can increase the hazard of personal injury. • Before leaving the operator’s position: – disengage the power take-off and lower the attachments; – change into neutral and set the parking brake; – stop the engine and remove the key. • Disengage drive to attachments, stop the engine, and disconnect the spark plug wire(s) or remove the ignition key – before clearing blockages or unclogging chute; – before checking, cleaning or working on the lawn mower; – after striking a foreign object. Inspect the lawn mower for damage and make repairs before restarting and operating the equipment; – if the machine starts to vibrate abnormally (check immediately). • Disengage drive to attachments when transporting or not in use. • Stop the engine and disengage drive to attachment – before refuelling; – before removing the grass catcher; – before making height adjustment unless adjustment can be made from the operator’s position. • Reduce the throttle setting during engine run-out and, if the engine is provided with a shut-off valve, turn the fuel off at the conclusion of mowing. Maintenance and Storage • Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition. • Never store the equipment with fuel in the tank inside a building where fumes can reach an open flame or spark. • Allow the engine to cool before storing in any enclosure. • To reduce the fire hazard, keep the engine, silencer, battery compartment and fuel storage area free of grass, leaves, or excessive grease. • Check the grass catcher frequently for wear or deterioration. • Replace worn or damaged parts for safety. • If the fuel tank has to be drained, this should be done outdoors. • On multi-bladed machines, take care as rotating one blade can cause other blades to rotate. • When machine is to be parked, stored or left unattended, lower the cutting means unless a positive mechanical lock is used.

Note: Determine the left and right sides of the

machine from the normal operating position. Adding Fuel Use unleaded regular gasoline suitable for automotive use (85 pump octane minimum). You may use leaded, regular gasoline if unleaded gasoline is not available. Important: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline. In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand. • Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark. • Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge. • When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground. • If this is not possible, refuel such equipment on a truck or trailer from a portable container, not from a gasoline dispenser nozzle. • If you must use a gasoline dispenser, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Using Stabilizer/Conditioner Use a fuel stabilizer/conditioner in the traction unit to provide the following benefits: • It keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained. 11

It cleans the engine while it runs

• It eliminates gum-like varnish buildup in the fuel system, which causes hard starting Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of gas stabilizer/conditioner to the gasoline. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use a fuel stabilizer/conditioner at all times. Filling the Fuel Tank 1. Stop the engine and wait for all moving parts to stop. 2. Clean around the fuel tank cap and remove it. 3. Add unleaded regular gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. Do not fill the fuel tank completely full. Do not fill the fuel tank completely full. Note: This space in the tank allows gasoline to expand. 4. Install the fuel tank cap securely. 5. Wipe up any gasoline that may have spilled. Checking the Engine Oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine Oil Level in Servicing the Engine Oil in the Maintenance section. Using the Parking Brake Always set the parking brake whenever you stop the machine or leave it unattended. Setting the Parking Brake 1. Push the brake pedal (Figure 3) down and hold it. 2. Turn the parking brake lever (Figure 3) counterclockwise and gradually take your foot off the brake pedal. Note: The clutch/brake pedal should stay in the depressed (locked) position. Releasing the Parking Brake 1. Push down on the brake pedal (Figure 3). Note: The parking brake lever should release. 2. Gradually release the brake pedal. Positioning the Seat The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. 1. Raise the seat and loosen the adjustment knobs (Figure 4). Figure 4 1. Adjustment knobs 2. Move the seat to the desired position and tighten the knobs. Using the Blade Control (PTO) The blade control (PTO) knob engages and disengages power to the blades. Engaging the Blades 1. Depress the brake pedal to stop the machine. 2.

Important: If the engine does not start after 15 seconds of continuous cranking, turn the ignition key to Off and let the starter motor cool for 2 minutes; refer to Troubleshooting. 8. After the engine starts, slowly shift the throttle control lever to Fast (Figure 12). Stopping the Engine 1. Move the throttle control lever to Slow (Figure 12). Note: If the engine backfires, shift the throttle control lever to the Fast position before stopping the engine. 2. Turn the ignition key to Off (Figure 12). Note: If the engine has been working hard or is hot, let it idle for a minute before turning the ignition key to Off. This allows the engine to cool the engine before you stop it. You may stop the engine in an emergency by turning the ignition key to Off. Using the Safety Interlock System Service Interval: Before each use or daily If the safety interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine. • Replace switches every 2 years regardless of whether they are operating properly or not. Understanding the Safety Interlock System The safety interlock system is designed to prevent the engine from starting unless: • You are sitting on the seat. • The brake pedal is depressed. • The blade control (PTO) knob is in the Disengaged position. • The traction control pedal is in Neutral. The safety interlock system stops the engine if you rise from the seat and the traction control pedal is not in the Neutral position, the parking brake is not set, or the blade control (PTO) knob is in the Engaged position. The safety interlock system is designed to stop the mower if: • You shift into Reverse with the blades (PTO) engaged. • You remove the bag or dump the grass. Setting the KeyChoice® Switch to Operate in Reverse The interlock feature on the machine prevents the power take-off (PTO) from operating when you back up the machine. If you operate the machine in reverse with the blades (PTO) engaged (i.e., with the mower blades or other attachment running), the engine will stop. Do not mow in reverse unless it is absolutely necessary. 15

If you need to use the blades (PTO) while backing

up, turn off the interlock feature using the KeyChoice switch located near the seat bracket (Figure 13). Figure 13 1. KeyChoice switch You could back over a child or bystander while the mower blades or other attachment is engaged and cause serious injury or death. • Do not mow in reverse unless it is absolutely necessary. • Do not insert the KeyChoice key unless it is absolutely necessary. • Always look backward and down before backing up the machine. • Use the KeyChoice switch only if you are certain that no children or other bystanders will enter the mowing area. • Be very observant after deactivating the interlock because the sound of the engine may prevent you from noticing that a child or bystander has entered the work area. • Always remove both the ignition and KeyChoice keys and put them in a safe place out of the reach of children or unauthorized users when you leave the machine unattended. 1. Engage the blades (PTO). 2. Insert the KeyChoice key into the switch (Figure 13). 3. Turn the KeyChoice key. A red light on the front console (Figure 14) turns on, indicating that the interlock is disabled. Figure 14 1. Operating-in-reverse light 4. Operate the machine in reverse and complete your task. 5. Disengage the blades (PTO) to activate the interlock. 6. Remove the KeyChoice key and put it in a safe place out of the reach of children. Testing the Safety Interlock System If the safety interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine. Test the safety interlock system before you use the machine each time. If the safety interlock system does not operate as described below, have an Authorized Service Dealer repair the safety interlock system immediately. While sitting in the seat, perform the following checks: 1. Set the parking brake, shift the blade control (PTO) knob to the Engage position, and turn the ignition key to Start: The engine should not crank. 2. Shift the blade control (PTO) knob to the Disengage position, release the parking brake, and turn the ignition key to Start: The engine should not crank. 3.

Before returning the grass collector to the operating position, move the machine forward to clear the grass collector of the deposited grass. 5. Slowly lower the telescoping dump lever to return the grass collector to the operating position. Towing Attachments The machine is equipped for towing attachments with a maximum weight of 150 kg (331 lb.). 1. Remove the grass collector; refer to Removing the Grass Collector. 2. Install the attachment to the towing hitch located at the lower rear part of the machine (Figure 18). Figure 18 1. Towing hitch Operating Tips • For the best performance, operate the engine at the maximum speed. The mower requires air to thoroughly cut grass clippings, so do not set the height-of-cut too low or completely surround the mower in uncut grass. Always leave one side of the mower free from uncut grass to allow the air to be drawn into the mower. • Cut the grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. When cutting grass longer than 6 inches (15 cm) tall, cut the lawn twice to ensure an acceptable appearance. • It is best to cut only about 1/3 of the grass blade. Do not cut more than that unless the grass is sparse or it is late fall when grass grows more slowly. • Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings and enhances decomposition and fertilization. • Grass grows at different rates at different times of the season. To maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. • If the grass is longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual, cut the grass at that setting, and then cut the grass again at the lower, normal setting. • If you must stop the machine while mowing, you may leave a clump of grass clippings on your lawn. To avoid this, do the following: – Engage the blades and move to a previously cut area. – Disperse the clippings evenly by raising the mower 1 or 2 height-of-cut settings while driving forward with the blades engaged. • Use the washout port to clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, the cutting quality will eventually become unsatisfactory. • Maintain sharp blades throughout the season. Sharp blades cut grass cleanly without tearing or shredding the grass blades. Tearing and shredding the grass turns it brown at the edges, which slows its growth and increases the chance of disease. Every 30 days, check the blades for sharpness and file down any nicks. 19

Note: Determine the left and right sides of the machine from the normal operating position.
