MACHINE PREPARATION 1. HANDLING THE PACKED MACHINE The machine is contained in specific packaging. It is not possible to place more than two packages on top of each other. The total weight is 220 lb (100kg). The overall dimensions of the package are: A: B: C: 45.1 in (1145mm) 26.2 in (665mm) 48.4 in (1230mm) 2. UNPACKING THE MACHINE 1. Remove the outer packaging 2. The machine is fixed to the pallet with wedges which block the wheels 3. Remove these wedges 4.
MACHINE PREPARATION 3. BATTERY INSTALLATION The machine will be supplied with a battery charger and either two 12V Wet or AGM batteries. The batteries must be housed in the battery tray in the battery compartment beneath the recovery tank. To insert the batteries you must: 1. Lower the squeegee and base 2. Open the rear hinge that secures the tank 3. Rotate the recovery tank as far as it will go, using the side handle 3 WARNING: To avoid acid spillage you can use sealed batteries.
MACHINE PREPARATION 5. BATTERY MAINTENANCE For maintenance and recharging, follow the instructions provided by the battery manufacturer. 6. BATTERY DISPOSAL When the battery reaches the end of its working life, it must be disconnected by certified professional, then lifted (using the handles and suitable lifting device) to remove it from the battery compartment. DEAD BATTERIES ARE CLASSIFIED AS HAZARDOUS WASTE AND MUST BE DISPOSED OF AT AUTHORIZED BATTERY DISPOSAL COMPANY. 7.
MACHINE PREPARATION 9. CONNECTING THE BATTERY CONNECTOR Connect the battery connector (2) to the machine connector (1) 1 2 11. BATTERY 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.
MACHINE PREPARATION 12. INSTRUMENT PANEL COMPONENTS The instrument panel components are identified as follows: 1- Paddles to activate brushes / traction (located beneath the grip) 2- ON/OFF key switch 3- battery level / hour-counter display 1 2 13.
MACHINE PREPARATION 16. ADJUSTING THE SQUEEGEE HEIGHT The height of the squeegee must be adjusted based on wear and tear of the squeegee blade. To do this, turn the knobs (2) counter clockwise to raise the squeegee, and clockwise to lower it. Note: the right and left wheels must be adjusted to the same level, so the squeegee can work parallel to the floor. 2 17. ADJUSTING THE SQUEEGEE INCLINATION During working operation, the rear squeegee blade is slightly tilted backwards (by about 0.
MACHINE PREPARATION 19. SOLUTION TANK Remove the front inlet cap and check the solution filter is correctly fitted. Check the filter cap (beneath the solution tank, at the back) is correctly closed. 20. SOLUTION TANK Fill the tank with clean water in the front fill location (1) at a temperature not exceeding 120°F (50°C). You can check the level of solution in the tank by means of the rear hose (2). Add the liquid detergent into the tank, in the concentration and manner specified by the manufacturer.
MACHINE PREPARATION 22. ASSEMBLING THE BRUSH 1. With the base up, insert the brush and position it in line with the plate beneath the base. 2. Lower the base, turn the key (1) to position “1”, push the paddles (2) on the handlebars. At this point, the brush is fixed.
OPERATION 1. MACHINE OPERATION 1. Connect the battery plug (1) to the machine plug 2. Turn the key (1) of the main switch to the "ON" position (clockwise). The battery charge level indicator lights will immediately come on. 3. Turn on the water valve (2) (the water falls automatically while the brushes are turning). 1 2 4. Release the lever (3) and lower the scrubbing head.
OPERATION 3. FORWARD MOVEMENTS The traction of these machines is obtained by means of the pad which, working slightly inclined, is able to drag the machine forwards. To move the machine, you must use the key then activate the paddles levers (1) on the handlebars. WARNING: when making even brief reverse movements, check the squeegee and base are raised. 4. OVERFLOW DEVICE The machine has a float in the filter basket that trips when the recovery tank is full to stop airflow into the vacuum hose.
SHUTTING DOWN THE MACHINE 1. AT THE END Proceed as follows when shutting down the machine and before you perform any type of maintenance: 1. 2. 3. 4. 5. Turn off the valve using its handle (1) Raise the brush deck using the pedal (2) Raise the squeegee using the lever (3) Turn off the key switch (4) Move the machine where the tanks can be drained 4 3 2 1 6. Remove the drainage hose from its compartment, unscrew the drainage cap and empty the recovery tank. 7.
DAILY MAINTENANCE 1. CLEANING THE RECOVERY TANK 1. Raise the vacuum cover (1) and prop it open using the lifting rod on the right-hand side of the lid. 2. Remove the drainage hose (2) from its fitting and empty the tank. 3. Rinse the inside of the tank well with water. 4. Reposition the cover on the machine and replace the drainage hose cap and drainage hose. 1 WARNING: Always wear gloves when doing this operation to protect yourself from contact with hazardous chemicals 2 2.
DAILY MAINTENANCE 4. CLEANING THE SQUEEGEE Ensure the squeegee is always clean, for better drying results. To clean it you must: 1. 2. 3. 4. 5. 6. Remove the hose from the squeegee Loosen the knobs (1) at the hose nozzle Remove and clean the nozzle Carefully clean inside the squeegee Carefully clean the squeegee blades Reassemble all the squeegee assembly 1 5. DISASSEMBLING THE PAD To disassemble the pad, proceed as follows: 2 1. Turn on the machine with the key switch 2.
WEEKLY MAINTENANCE 1. CLEANING THE SQUEEGEE HOSE Every week, or whenever vacuum seems to be unsatisfactory, check the squeegee hose for obstructions. To clean it, proceed as follows: 1. Remove the hose from the sleeve on the squeegee 2. Remove the other end from the recovery tank 3. Wash the inside of the hose with water introduced from the side where it is connected to the tank 4.
TROUBLESHOOTING GUIDE INSUFFICIENT WATER ON THE PAD 1. Check the valve – located beneath the symbol – (1) is turned on. 2. Check there is water in the solution tank. 1 THE MACHINE DOES NOT CLEAN WELL 1. Check the state of wear and tear of the pad and, if necessary, replace it. 2. Use a different kind of pad to the one fitted as standard.
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 140°F (60°C)). The Polypropylene brush is non-hydroscopic 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 140°F (60°C)).
