GENERAL SAFETY REGULATIONS The regulations below must be carefully followed in order to avoid harm to the operator and damage to the machine. • Read all 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 authorized and trained personnel. • When operating the machine be careful of other people. • The machine is not designed for cleaning carpets.
MACHINE PREPARATION 1. HANDLING THE PACKED MACHINE Do not place more than two packages on top of each other. The total weight is 220 lb. (100 kg). The overall dimensions of the package are: A : 45.1 in (1145 mm) B : 26.2 in (665 mm) C : 48.4 in (1230 mm) 2. HOW TO UNPACK THE MACHINE A. Remove the outer packaging. B. The machine is placed on the pallet with wedges which block the wheels. C. Remove these wedges. D. Use a ramp to get the machine down from the pallet, pulling it backwards. E.
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: A. Lower the squeegee and brush deck. B. Open the rear latch (2) that secures the tank. C. 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 a certified professional, then lifted (using the handles and suitable lifting device) to remove it from the battery compartment. USED BATTERIES ARE CLASSIFIED AS HAZARDOUS WASTE AND MUST BE DISPOSED OF AT AUTHORIZED BATTERY DISPOSAL SITE. 7.
MACHINE PREPARATION 9. CONNECTING THE BATTERY CONNECTOR Connect the battery connector (2) to the machine connector (1) 10. BATTERY INDICATOR The battery indicator uses LEDs and has 8 positions (7 yellow - charged batteries, and 1 red - discharged 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 11. INSTRUMENT PANEL COMPONENTS The instrument panel components are identified as follows: A. Levers to activate brushes / traction (located beneath the grip) B. ON/OFF key switch C. Battery level / hour meter 12. REAR COMPONENTS The rear components are identified as follows: A. Foot pedal to raise the brush deck B. Water / solution level hose C. Drain hose with recovery tank cap D. Latch to close the tanks E. Storage compartment F. Lever to raise the squeegee G. Solution filter 13.
MACHINE PREPARATION 15. ADJUSTING THE SQUEEGEE HEIGHT The height of the squeegee must be adjusted based on wear 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 works parallel to the floor. 16. ADJUSTING THE SQUEEGEE INCLINATION During working operation, the rear squeegee blade is slightly bent backwards (by about 0.
MACHINE PREPARATION 18. SOLUTION TANK Remove the front inlet cap and confirm the solution filter is correctly installed. Confirm the filter cap (beneath the solution tank, at the back) is correctly closed. 19. SOLUTION TANK Fill the tank with clean, room temperature water through the front fill location (1). Water temperature not to exceed 120°F (50°C). You can check the level of solution in the tank by reviewing fluid level in the sight tube (2).
OPERATION 1. MACHINE OPERATION A. Connect the battery plug to the machine plug. B. Turn the key (1) of the main switch to the "ON" position (clockwise). The battery charge level indicator lights will immediately turn on. C. Turn on the water valve (2) (the water dispenses automatically when the brush is turning). D. Release the lever (3) and lower the brush deck. E. Lower the squeegee, by rotating the squeegee lift lever (4) counter clockwise. The vacuum motor will turn on. F.
OPERATION 2. FORWARD MOVEMENTS The traction of these machines is obtained by means of the pad which, working slightly inclined, is able to pull the machine forward. To move the machine, activate the switch levers (1) on the handlebars. WARNING: When moving in reverse lift the squeegee. 3. OVERFLOW DEVICE The machine has a shut off float in a filter basket that activates when the recovery tank is full and stops airflow into the vacuum hose.
SHUTTING DOWN THE MACHINE 1. AFTER FINISHED CLEANING Do the following when shutting down the machine and before you perform any type of maintenance: A. Turn off the solution valve using the knob (1) B. Raise the brush deck using the foot pedal (2) C. Raise the squeegee using the squeegee lift lever (3) D. Turn off the key switch (4) E. Move the machine where the tanks can be drained. F. Remove the drain hose from its holder, unscrew the drain cap and empty the recovery tank. G.
DAILY MAINTENANCE 1. CLEANING THE RECOVERY TANK A. B. C. D. Raise the vacuum cover (1). Remove the drain hose (2) from its holder and empty the tank. Rinse the inside of the tank with water. Close the recover tank cover on the machine and replace the drain hose cap and drain hose. WARNING: Always wear gloves when doing this operation to protect yourself from contact with hazardous chemicals. 2. CLEANING THE VACUUM FILTER A. B. C. D. E. F. Raise the recover tank cover.
DAILY MAINTENANCE 4. CLEANING THE SQUEEGEE For the best floor drying performance keep the squeegee clean. To clean it: A. Remove the vacuum hose from the squeegee. B. Loosen the knobs (1) that hold the squeegee shoe adapter. C. Remove and clean the squeegee shoe adapter. D. Carefully clean inside the squeegee. E. Carefully clean the squeegee blades. F. Reassemble all the squeegee components. 5. REMOVING THE PAD To remove the pad driver: A. Turn on the machine with the key switch. B.
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: A. Remove the hose from the sleeve on the squeegee. B. Remove the other end from the recovery tank. C. Wash the inside of the hose with water introduced from the side where it is connected to the tank. D. Reassemble the hose.
TROUBLESHOOTING GUIDE INSUFFICIENT WATER ON THE PAD 1. Check the valve – located beneath the symbol – (1) is turned on. 2. Confirm that there is water in the solution tank. THE MACHINE DOES NOT CLEAN WELL 1. Check the condition of the pad and, if necessary, replace it. 2. For cleaning floors where the dirt is particularly resistant, we recommend the use of special brushes supplied upon request and according to needs. THE SQUEEGEE DOES NOT DRY EFFECTIVELY 1. Confirm that the squeegee blades are clean. 2.
