the tank has been completely emptied.
• Close the drain valve.
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
whenever required, and even during intermediate
phases of the work cycle.
Always empty the recovery tank before lifting it
to avoid health problems for operators and to avoid
damaging the machine.
The recovery tank volume is higher than the de-
tergent solution volume, therefore a potentially
dangerous 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 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 drain-
age point.
The emptying operation can be interrupted quickly
and whenever required just by raising the drain
hose.
Check the quantity of residual dirt in the tank and,
if necessary, clean the interior through the inspec-
tion hole, lifting the cover and the funnel at the
top.
Carefully position the funnel inside the inspection
hole and close the top cover, tightening the lock
handles after each inspection/cleaning operation.
Fully tighten the drain hose with the screw plug
and hang it on the support behind the machine.
☞ The top cover of the tank and the drain hose
plug must be airtight, otherwise the subsequent
pressure loss will reduce drying efficiency.

DRIVING THE MACHINE
Select the running direction using the Forward/
Reverse lever.
Insert and turn the ignition key.
Using the right foot lightly press the accelerator
pedal and drive the machine to its destination.
Turn off the machine and remove the keys from
the control panel.
The running direction can be changed using the
forward/reverse lever, even while pressing on the
accelerator pedal.

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 operat-
ing 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.
• Direction lever, to select forward or reverse move-
ments.
• Speed regulator, to select the maximum advance-
ment speed when the pedal is fully depressed.
• Brush switch, to turn on the brush rotation motor.
• Brush position switch, to lower (work position) or
raise (rest/movement position) the brush unit on/
from the floor.
• Suction switch, to turn on the suction motor.
• Squeegee position switch, to lower (work posi-
tion) or raise (rest/movement position) the squee-
gee.
• Emergency switch, to cut off/restart all pro-
grammed work operations.
• Right advancement pedal, to start moving the
machine.
• Solution flow adjustment lever, to regulate the
quantity (maximum toward the top, minimum to-
ward the bottom) of detergent solution to be ap-
plied on the floor.
• Battery charge control, the sequence of lights
progressively turns off until the battery is dis-
charged. 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
charging area to charge the battery. If these opera-
tions are not carried out, the machine will auto-
matically deactivate the brush motor and it will only
be possible to move the machine. In this situation if
the machine is not stopped right away, all functions
will be cut off automatically, and the machine will
have to be moved by hand.
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 dis-
charge control devices.
