After the detergent solution is finished, always empty
the recovery tank before filling it again.
In general, the recovery tank can be emptied whene-
ver required, and even during intermediate phases 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 suction
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 suction
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 neces-
sary, 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 subsequent
pressure loss will reduce drying efficiency.

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 with the battery charge
power test placed on the control panel and, if suffi-
cient, select with the speed adjusting knob the run-
ning speed wanted; put the brush motor switch and
the suction motor switch to the ON position in order
to set the motors in the operating mode.
Adjust the solution water outlet with the control lever
placed in the back of the machine; lower the squee-
gee unit by lowering the control level and the brush
plate with the foot pedal at the back of the machine.
To start working, pull the control lever upwards; the
brush rotation will start and the machine will start
moving forward. Releasing the control lever the ma-
chine will stop and the brush rotation will stop after
few seconds.
Push the control lever down to move reverse.
• Remember to lift the squeegee before driving re-
verse to avoid damaging it.

WORK METHOD
6.6.1. 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 operating cor-
rectly, reducing drying efficiency.
This machine can driven only by trained personnel.
6.6.2. 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 resi-
dual moisture and go to the battery charging 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: follow
the instructions in the troubleshooting section and
contact a specialised worker to check the discharge
control devices.
6.6.3. 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 control key.
Now open the solution cock by lowering the deter-
gent dosage lever which is at the back of the machine,
lower the suction unit by lowering the squeegee con-
trol level, lower the washing unit, levering 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 squeegee before driving re-
verse to avoid damaging it.
