move and get sensitive parts of the machine wet.
Close the tank with its plug...
To drain:
• Unscrew the cock.
• Close the drainage plug firmly.

7.5 DRAINING THE RECOVERY TANK

The dirty water must be drained in accordance with
national regulations.
The user is completely responsible for ensuring
compliance with such rules.
After the detergent solution is finished, always
empty the recovery tank before filling it again.
In general, the recovery tank can be emptied whe-
never required, and even during intermediate pha-
ses of the work cycle.
The recovery tank volume is higher than the deter-
gent solution volume, therefore a potentially dan-
gerous situation for the suction motor should never
occur. In any case, a safety float turns off the suc-
tion motor if the dirty liquid level is too high.
( ) If water or foam starts leaking from under the
tanks for any reason, immediately turn off the suc-
tion motor and empty the recovery tank.
To drain the tank:
Drive the machine to a suitable location to drain the
dirty water and preferably near a toilet or a sewer
drain (comply with the national regulations for
waste water disposal).
Turn off the machine and remove the key from the
panel.
Detach the drain hose from the hook and, keeping
it high, unscrew the plug.
Lower the drain hose toward the selected drainage
point.
The emptying operation can be interrupted quickly
and
whenever required just by raising the drain hose.
Check how much dirt is still in the tank and, if ne-
cessary, wash it inside through the inspection hole
by unscrewing the rear window .
Fully tighten the drain hose with the screw plug and
hang it on the support behind the machine. The
drain hose plug must be airtight, otherwise the sub-
sequent pressure loss will reduce drying efficiency.

7.6 DRIVING THE MACHINE

Check connection between the power and battery
connectors, located under the control panel.
Put the ignition key in and turn it.
Check battery charge status via the control unit and,
if sufficient, select the running speed wanted, ope-
rate the brush control key and the suction control
key. Now open the solution cock by lowering the de-
tergent dosage lever which is at the back of the ma-
chine, lower the suction unit by lowering the
squeegee control level, lower the washing unit, le-
vering with your foot on the brush plate control lever.
Move forwards, pulling the forward lever up . Re-
member to lift the floor cleaner before reversing to
avoid damaging it.

7.7 WORK METHOD

7.7.1 PREPARATION AND WARNINGS

Remove any loose solid residue from the surface to
be treated (using suitable tools, such as vacuum
cleaners, sweepers, etc.). It this is not done, the
solid dirt might prevent the squeegee from opera-
ting correctly, reducing drying efficiency.
This machine can driven only by trained personnel.

7.7.2 OPERATING CONTROLS

• Ignition key, to turn the machine on and off.
• Brush switch, to turn on the brush rotation motor
Pedal to raise/lower the brush unit off/on to the
ground.
• Suction switch, to turn on the suction motor
• Solution flow adjustment lever, to regulate the
quantity (maximum toward the bottom, minimum
toward the top) of detergent solution to be applied
on the floor .
• Battery charge control, the sequence of lights pro-
gressively turns off until the battery is discharged .
When the red light turns on, turn off the brush
motor, close the solution supply, finish drying the
small residual moisture and go to the battery char-
ging area to charge the battery.
!
( ) The batteries may be irreparably damaged if
the residual charge level drops too low (see the
battery operating manual). Do not force the battery
discharge beyond the safety limits, turning the key
off and on or in any other manner.
!
( ) When an abnormal situation occurs, such as
when the machine doesn't have enough power and
the safety devices don't trip, stop immediately: fol-
low the instructions in the troubleshooting section
and contact a specialised worker to check the di-
scharge control devices.
7.7.3 DIRECT SCRUBBING OR FOR SLIGHTLY
DIRTY SURFACES
Scrubbing and drying in a single pass.
Prepare the machine as previously described.
Check connection between the power and battery
connectors, located under the control panel.
Put the ignition key in and turn it.
Check battery charge status via the control unit
and, if sufficient, select the running speed wanted,
operate the brush control key and the suction con-
trol key. Now open the solution cock by lowering
the detergent dosage lever which is at the back of
the machine, lower the suction unit by lowering the
squeegee control level, lower the washing unit, le-
vering with your foot on the brush plate control
lever .
Move forwards, pulling the forward lever up or push
it down to reverse . Remember to lift the floor clea-
