GENERAL SAFETY REGULATIONS The regulations below must be carefully followed in order to avoid harm to the operator and damage to the machine. Read the labels on the machine carefully. Do not cover them for any reason and replace them immediately if they become damaged. The machine must be used exclusively by authorised and trained personnel.
MACHINE PREPARATION 1. INTENDED USE The scrubbing machine is designed exclusively for the professional cleaning of surfaces and floors in industrial, commercial and public environments. In addition, only use the machine in closed or at least covered environments. 2. HANDLING THE PACKED MACHINE The machine is contained in specific packaging with a pallet for the handling with fork trucks.
MACHINE PREPARATION 4. 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. The dimensions of the battery compartment are: 384 x 520 x H340 mm.
MACHINE PREPARATION 6. BATTERY CHARGER CONNECTION (only versions without CB) The battery connector is found in the battery compartment by opening the recovery tank. The connector (1), connected to the batteries, must be detached from machine connector (2) and hooked up to the battery charger connector for charging. The coupling connector is delivered in a bag inside the battery compartment, and must be connected to the cables of the battery charger as indicated in the instructions (see the battery charger manual).
MACHINE PREPARATION 8. TYPE OF BATTERY To power the machine it is necessary to use: - liquidelectrolyte lead traction batteries; - sealed traction batteries with gas recombination or gel technology. OTHER TYPES MUST NOT BE USED. The batteries must meet the requisites laid out in standards CEI EN 60254-1:2005-12 (CEI 21-5) + CEI EN 60254-2:2008-06 (CEI 21-7).
MACHINE PREPARATION 10. BATTERY CHARGE LEVEL INDICATOR The battery indicator uses LEDs and has 8 positions (7 yellow - charged batteries, and 1 red - run down batteries). WARNING: A few seconds after the red indicator light comes on, the brush motor switches off automatically. With the remaining charge it is possible to complete the drying process before recharging 11.
MACHINE PREPARATION 14. DISC BRUSH ASSEMBLY 1. Lift the base by turning the right lever (1) to move the base counterclockwise. WARNING: During this operation, check there are no people or objects near the brush. 2. With the base up, insert the brushes in the plate housing beneath the base, turning them until the three pins enter the niches in the plate itself;...
MACHINE PREPARATION 16.DETERGENT SOLUTION Fill with clean water at a temperature not exceeding 50°C. The solution tank can be filled either through the opening (1) with a screw cap, or the rubber cap (2), which also supports the water hose. If the supply is made via the rubber cap, unscrew the cap to allow the air to vent correctly.
WORK PREPARING TO WORK 1. Carry out the operations to prepare the machine. 2. Connect the connector to the batteries (1). 3. Sit on the driver’s seat. 4. Check the parking brake is released (2). 5. Turn the key of the main switch a quarter of a turn clockwise. Immediately, on the instrument panel, the display will turn on indicating the charge level of the batteries.
WORK WARNING: If problems arise during operations, turn off the key, engage the parking brake by pushing the lever (9) to the left until the machine brakes and release the emergency lever placed below the operator. These commands block all moving machine parts.
WORK ACOUSTIC ALARM The machine is equipped with a buzzer controlled by button (15) on the right side of the steering column. FLASHING LIGHT (on request) The machine is equipped for a flashing light that turns on automatically when the key in the main switch is turned on.
AT THE END OF THE WORK At the end of the work, and before carrying out any type of maintenance, perform the following operations: 1. Close the tap (1). 2. Lift the base by turning the right lever (2) counterclockwise, then lift the squeegee turning the left lever (3) clockwise.
DAILY MAINTENANCE CLEANING THE RECOVERY TANK 1. Disconnect the tube (1) from its seat, unscrew the drainage cap and empty the recovery tank. WARNING: This operation must be carried out using gloves to protect against contact with dangerous solutions. WARNING: Before performing any maintenance, remove the keys from the panel and disconnect the battery connector of the machine.
DAILY MAINTENANCE CLEANING THE SOLUTION TANK AND FILTER: 1. Disconnect the clean water drainage pipe (1) from its housing on the left side of the machine, unscrew the cap and empty the tank. 2. Remove the plug from the solution tank refill opening. 3.
WEEKLY MAINTENANCE CLEANING THE SUCTION TUBE Whenever suction seems to be unsatisfactory, check that the suction tube (1) is not obstructed. If necessary clean with a jet of water as follows: 1. Detach the aspiration tube from the seat on the recovery tank. 2.
EXTRAORDINARY MAINTENANCE REPLACING THE FRONT SQUEEGEE RUBBER Suction will be poor and the machine will not dry perfectly if the front squeegee rubber is worn. Proceed as follows to replace: 1. Remove the squeegee from the support arm by unscrewing the handwheel. 2.
TROUBLESHOOTING INSUFFICIENT WATER ON THE BRUSHES 1. Check there is water in the solution tank (1). 2. Check that the tap (2) is open. 3. Clean the solution filter located at the front of the machine. THE SQUEEGEE DOES NOT DRY PERFECTLY 1.
TROUBLESHOOTING THE SUCTION MOTOR DOES NOT FUNCTION 1. Check whether the recovery tank is full and, if necessary, empty it. 2. Check the float switch on the suction cap (see also “CLEANING THE RECOVERY TANK” in the chapter “DAILY MAINTENANCE”). THE BRUSH MOTOR DOES NOT WORK ATTENTION To avoid damaging the floor, the motor only starts up when the machine is moved forwards.
TROUBLESHOOTING ELECTRIC FUSES AND THERMAL CUT-OUTS In addition to general 80 A fuses, the machine is also fitted with self-restoring safety fuses located on the boards in the electric system that interrupt the power supply to the brush and suction motors when the machine exceeds the predetermined load. To restore the power supply to the motor, switch off the machine and wait for the fuses to cool down (about 40 seconds).
CHOOSING AND USING THE BRUSHES 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.
