On the bottom line you can see what battery technology has been set for machine operation; in this case it is gel batteries (to set another type of battery - for instance acid - contact the qualified assistance centre personnel). 9. The third and last screen (known as “work”) displays the battery charge status and the total functioning time. When the batteries supplied are fully charged, the bottom line contains ten light indicators that represent a battery. As the batteries gradually run down, the indicators go out and, with the batteries completely run down, only the battery outline flashes. The top line indicates the hours and minutes of functioning. The flashing “:” symbol Indicates that the hour meter is counting the machine functioning time. 10. Move the tap lever (5) downwards and adjust to the desired solution quantity 11. Lower the brush head by turning the right lever (6) clockwise, then lower the squeegee turning the left lever (7) anticlockwise. WARNING: As soon as the forward movement pedal is activated with the brush head in its work position, the solenoid valve will start working and will begin dispensing detergent solution. As soon as the squeegee is in its work position, the vacuum motor will switch on and being working. 12. Press the accelerator pedal (8) to start moving the machine WARNING: To stop the machine, remove your foot from the accelerator (8). The machine will begin to stop. 20 WORK 3 4 5 7 6 8
13. To make a reverse movement, press the button (9) on the steering wheel simultaneously with the pedal (8). WARNING: During reverse movements, the squeegee must be lifted off the floor. To do this, turn the lever (7) clockwise. During the first metres, check there is sufficient solution and that the squeegee dries perfectly. The machine will now begin to work with full efficiency until the battery is flat or until the detergent solution has finished. 29. "ECO" DEVICE The machine is equipped with an "ECO" function which increases the working capacity of the machine. Press the button (1) on the steering wheel to activate the "ECO" function; the battery display will show the word "ECO". When this function is activated, the power of the vacuum and brush motors is reduced and therefore also the noise level of the machine. Just press the button (1) on the steering wheel to deactivate the "ECO" function. 30. OVERFLOW DEVICE The machine is NOT equipped with an overflow device, because the capacity of the recovery tank is greater than the capacity of the solution tank. In extraordinary cases, there is a mechanical device (float) on the lid that, when the recovery tank is full, shuts off the air to the suction motor intake TO protect it; the sound of the vacuum motor will then be deeper. In this case, raise the brush head and squeegee off the floor by means of the respective knobs on the steering column. After about 15-25 seconds, the vacuum motor will switch off. Then empty the recovery tank via the drainage hose (1). It is good practice when restoring the level of the solution tank, to empty the recovery tank through the special drainage pipe (1). 31. EMERGENCY BUTTON If there are any problems while you are working, press the emergency button (1) beneath the seat. This command interrupts the electric circuit between the batteries and the machine system, so the machine stops and the electric brake is triggered. To resume work (after resolving the problem), switch off the key (2), move the button (1) to its standard position, then switch the key (2) back on again. 21 WORK 8 9 9 1 1 2 1

Clean the entire vacuum unit (see “WEEKLY MAINTENANCE”) 4. Replace the rubbers, if worn 45. THE MACHINE DOES NOT CLEAN WELL 1. Check the state of wear and tear of the brushes and, if necessary, replace them. The brushes should be changed when the bristles are about 15mm long. To replace them, see “REPLACING THE BRUSHES”, or “DISASSEMBLING THE BRUSHES” and “ASSEMBLING THE BRUSHES”. Working with over-worn brushes may cause damage to the floor. 2. 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”). 46. 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. 47. 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 paragraph “DAILY MAINTENANCE”) 48. THE BRUSH MOTOR DOES NOT WORK WARNING To avoid damaging the floor, the motor only starts up when the machine is moved forwards 1. Check that the base is lowered during start-up 2. The operator must be properly seated in the driving position 3. Check no thermal protection device has intervened. 4. Check the correct connection of the motor to the terminal under the footboards. 29 TROUBLESHOOTING 1 2
To dispose of the machine, take it to a demolition centre or an authorised collection centre. Before scrapping the machine it is necessary to remove and separate the following materials and send them to the appropriate collection centres in accordance with the environmental hygiene regulations currently in force: brushes felt electric and electronic parts* batteries plastic parts (tanks and handlebars) metal parts (levers and frame) (*) In particular, to scrap the electric and electronic parts, contact your area distributor. 30 DISPOSAL
POLYPROPYLENE BRUSH (PPL) Used on all types of floor, it has good resistance to wear and tear and hot water (no greater than 60°C). PPL 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, also because, 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 holder is especially suitable for machines with several brushes, where the centring of the abrasive floor pads is difficult.
