When the machine is delivered to the customer, an immediate check must be performed to ensure all the material mentioned in the shipping documents has been received, and also to check the machine has not been damaged during transportation. If this is the case, the carrier must ascertain the extent of the damage at once, informing our customer service office. It is only by prompt action of this type that the missing material can be obtained, and compensation for damage successfully claimed. Introductory comment This is a floor scrubber-dryer which, via the abrasive mechanical action of the two rotating brushes and the chemical action of a water/detergent solution, can clean any type of flooring. As it advances, it also collects the dirt removed and the detergent solution not absorbed by the floor. The machine must be used only for this purpose. Even the best machines will only work well if used correctly and kept in good working order. We therefore suggest you read this instruction booklet carefully and read it again whenever difficulties arise while using the machine. If necessary, remember that our assistance service (organised in collaboration with our dealers) is always available for advice or direct intervention.

The machine is contained in specific packaging with a pallet for the handling with fork trucks. It is not possible to place more than two packages on top of each other. The total weight is 136kg The overall dimensions of the package are: A: 1260 mm B: 660 mm C: 1230 mm A C B HOW TO UNPACK THE MACHINE 1. Remove the outer packaging 2. The machine is fixed to the pallet by means of a strap 3. Remove the strap 4. Use a chute to get the machine down from the pallet, pushing it backwards. Avoid violent blows to the base 5. Keep the pallet for any future transport needs.

To power the machine you can use:  two lead traction batteries with tubular plates and free electrolyte;  two airtight traction batteries with gas recombination gel technology. Each battery consists of elements connected in series so as to provide the clamps with a voltage of 24V. The maximum dimensions of each battery are: - width: 195mm, length: 360 mm, height: 250 mm The maximum weight of each of the two batteries is 20 kg. To obtain a voltage of 24V, they must be connected together in series by specialised personnel trained at the ICE Technical Assistance Centre FITTING THE BATTERIES INTO THE MACHINE The batteries must be housed in the special compartment beneath the recovery tank. They should be handled using lifting equipment that is suitable in terms of both weight and hook-up system. They must also satisfy the requirements of Standard CEI 21-5. To insert the batteries you must: 1. Open the recovery tank cover, bringing it forwards. 2. detach the squeegee tube (1) from the recovery tank 3. unthread the suction cap (2) by rotating it anticlockwise 4. detach the “recovery tank” drainage tube from its hook 5. remove the recovery tank 2 1 6. Position the batteries. 7. Connect the battery connector (2) to the machine connector (1). 8. Reassemble all the elements WARNING! All installation and maintenance operations must be carried out by specialised personnel 2 1 CONNECTING THE BATTERY CHARGER Beneath the recovery tank cover there is the battery connector (2), in which the battery charger connector must be inserted. The coupling connector of the battery charger is consigned inside the bag containing this instruction booklet, and must be assembled on the cables of the battery charger as indicated in the instructions. WARNING! This process must be carried out by qualified personnel. The incorrect or imperfect connection of the cables to the connector can cause serious harm to people and damage to objects. 2

Check the battery charger is suitable for the batteries installed, in terms of both capacity and type (lead/acid or GEL and equivalents). WARNING: never charge a GEL battery with an unsuitable battery charger. Follow the instructions given by the battery/battery charger manufacturer with the utmost attention. In order not to cause permanent damage to the batteries it is essential to avoid their complete discharge: arrange the recharge within a few minutes of the switching on of the flashing "discharged batteries" signal. NOTES: never leave the batteries completely discharged, even if the machine is not being used. WARNING! For the daily recharging of the batteries, you must fully respect the indications provided by the manufacturer or retailer. All installation and maintenance operations must be carried out by specialised personnel. Danger of exhalation of gas and leakage of corrosive liquids. Danger of fire: do not go near with naked flames BATTERY INDICATOR The battery indicator is digital, with 4 fixed positions and a flashing one. The numbers which appear on the display show the approximate charge level. 4 = maximum charge, 3 = 3/4 charge, 2 = 2/4 charge, 1 = 1/4 charge, 0 = discharged batteries (flashing) WARNING! A few seconds after the appearance of the flashing “0”, the brush motor switches off automatically. With the remaining charge it is possible to complete the drying process before starting the recharge. ASSEMBLING THE SQUEEGEE For packaging reasons, the squeegee is supplied disassembled from the machine, and must be assembled as shown in the figure, inserting the clip into the small column of the squeegee. Insert the squeegee tube in the special sleeve.

The height of the squeegee must be adjusted on the basis of the state of wear and tear of the rubber. To do this, turn the wing nuts (1) anticlockwise to raise the squeegee, and clockwise to lower it. Remarks: the right and left wheels must be adjusted to the same level, so the squeegee can work parallel to the floor. 1 ADJUSTING THE SQUEEGEE INCLINATION During working operation, the rear rubber is tilted slightly backwards (by about 5mm) in a uniform way for its whole length. If it is necessary to increase the bend of the rubber in the central part, you must tilt the squeegee backwards, rotating the adjuster (1) anticlockwise. To increase the bend of the rubber at the sides of the squeegee, rotate the adjuster clockwise. When fully adjusted, fix the lock nut. 5mm RECOVERY TANK Open the cover and check the suction cap (2) is correctly blocked (insert the notches in their housings, rotating the cap clockwise) and correctly connected to the tube leading to the suction motor. In addition, check the squeegee tube (1) is correctly inserted in its housing, and that the drainage tube cap (in the rear part of the machine) is closed. 1 2 DETERGENT SOLUTION Fill the solution tank with clean water at a temperature no greater than 50°C and add liquid detergent in the proper concentration, following the instructions of the manufacturer. The formation of excess foam could damage the suction motor, so use only the minimum amount of detergent necessary. Reassemble the cap. WARNING! always use low foam detergent. To avoid the production of foam, before starting to clean, put a minimum quantity of antifoam liquid into the recovery tank. Never use pure acid.

For packaging reasons, the splash guard is supplied disassembled from the machine, and must be assembled as shown in the figure. ASSEMBLING THE BRUSH 1. Raise the base by means of the appropriate pedal. 2. With the base up, position the brush in line with the coupling on the machine. 3. Lower the base by means of the pedal. 4. Using the "man present" lever (6), the brush is automatically hooked up. 6 5. To alter the machine forwards speed, use the knob shown in the figure.

Press the brush switch (2) 4. press the suction switch (3) 3 2 5. By means of the tap lever (4), regulate the quantity of detergent solution - it must be sufficient to wet the floor evenly, but not so much that it leaks from the splash guard. Remember, however, that the correct quantity of solution always depends on the type of floor, the degree of dirtiness and the speed used. 6. Release the pedal to lower the base. 7. Lower the squeegee by means of the lever (5) 5 4 8. Via the "man present" lever (6), the brushes begin to rotate and the squeegee begins to suck in. 9. During the first metres, check there is sufficient solution and that the squeegee dries perfectly. 6

causing the suction tube to close. In this case, it is necessary to empty the recovery tank, removing the drainage tube cap. WARNING! This operation must be carried out wearing gloves to protect against contact with dangerous solutions. FORWARD MOVEMENTS The traction of these machines is obtained by means of the brush(es) which, working slightly inclined, drag the machine forwards. To move the machine, you must raise the brush base and then move it via the knobs on the handlebars. WARNING! When making even brief reverse movements, check the squeegee is raised.

At the end of the work, and before carrying out any type of maintenance: 1. Close the tap by means of the lever (1). 2. Raise the base by means of the pedal. 3. raise the squeegee by means of the lever (2) 2 1 4. Turn off the brush switch (3). 5. Turn off the suction motor switch (4). WARNING! If the battery indicator display is still switched on after you have turned off the brush switch (3), this means the tap is turned on: turn off the tap via the lever (1) to prevent detergent solution leaking out. 6. bring the machine to the place provided for draining the water 4 3 7. Grasp the tube on the rear of the machine 8. Remove the drainage cap and empty the tank. WARNING!

Loosen the filter on the lower rear side of the machine 2. Rinse with a jet of water 3. Reassemble all the elements WARNING! During this operation, check there are no people or objects near the brush

Every week, or whenever suction seems to be unsatisfactory, check the squeegee tube is not obstructed. To clean it, proceed as follows: 1. Unthread the tube from the sleeve on the squeegee 2. Remove the other end from the recovery tank 3. Wash the inside of the tube with a water jet introduced from the side where it is connected to the tank 4. To reassemble the tube, repeat the above-mentioned operations in the reverse order WARNING! Do not wash the tube running between the suction unit and the suction cap CLEANING THE SOLUTION TANK 1. Loosen the solution tank cap 2. Rinse with a jet of water 3. Remove the drainage cap (1) and empty the tank WARNING! This operation must be carried out wearing gloves to protect against contact with dangerous solutions 1 REPLACING THE SQUEEGEE RUBBERS Check the state of wear and tear of the squeegee rubbers and, if necessary, replace them. To replace them you must: 1. Unthread the squeegee tube from the sleeve 2. Remove the pin from the small column 3. Disassemble the squeegee from its support 4. Loosen, by two turns, the knobs (1) blocking the rubber-pressing blades, and Remove them 5. Replace the rubbers To reassemble the squeegee, repeat the above-mentioned operations in the reverse order 1

Check that the tap (1) is turned on. Check there is water in the solution tank 1 THE MACHINE DOES NOT CLEAN WELL Check the state of wear and tear of the brushes and, if necessary, replace them (the brushes must be replaced when the bristles are about 15mm long). To replace the brushes, see “DISASSEMBLING THE BRUSHES” and “ASSEMBLING THE BRUSHES”. Use a different kind of brush to the one fitted as standard. For cleaning floors where the dirt is particularly resistant, we recommend the use of special brushes supplied upon request and according to needs (see “CHOOSING AND USING THE BRUSHES”). THE SQUEEGEE DOES NOT DRY PERFECTLY 1. Check the squeegee rubbers are clean 2. Adjust the inclination of the squeegee (see "SQUEEGEE" under “MACHINE PREPARATION”) 3. Check the suction tube is correctly inserted in its housing on the recovery tank 4. Disassemble the entire suction unit and clean it 5. Replace the rubbers, if worn 6. Check the suction motor switch is turned on 7. Check wheel adjustment EXCESSIVE FOAM PRODUCTION Check that a low foam detergent has been used. If necessary, add a small quantity of antifoam liquid to the recovery tank. Remember that, when the floor is not very dirty, more foam is generated. In this case the detergent solution should be more diluted.

POLYPROPYLENE BRUSH (PPL) Used on all types of floors. Good resistance to wear and tear, and hot water (no greater than 60°C). The Polypropylene brush is non-hygroscopic and therefore retains its characteristics even when working in wet conditions. NYLON BRUSH Used on all types of floors. Excellent resistance to wear and tear, and hot water (even over 60°C). The nylon is hygroscopic and so tends to lose its characteristics over time when working in wet conditions. ABRASIVE BRUSH The bristles of this type of brush are charged with highly aggressive abrasives. It is used to clean very dirty floors. To avoid floor damage, work only with the pressure strictly necessary. THICKNESS OF THE BRISTLES Thicker bristles are more rigid and are therefore used on smooth floors or floors with small joints. On uneven floors or those with deep joints, it is advisable to use softer bristles which can enter the gaps more easily. Remember that when the bristles are worn and therefore too short, they will become rigid and are no longer able to penetrate and clean deep down. In this case, like with over-large bristles, the brush tends to jump. PAD HOLDER The pad holder is recommended for cleaning shiny surfaces. There are two types of pad holder: 1. the traditional pad holder is fitted with a series of anchor points that allow the abrasive floor pad to be held and dragged while working 2. the CENTER LOCK type pad holder not only has anchor points, but also a snap-type central locking system in plastic that allows the abrasive floor pad to be perfectly centred and held without any risk of it becoming detached. This type of dragging device is recommended above all for machines with more than one brush, where the centring of the abrasive discs is difficult.
