• Do not leave the water hose unattended and in-
sert it completely into the tank: the hose might
move and get sensitive parts of the machine
wet.
• Close the tank cover.
To drain the solution water tank:
• Open the valve located at the bottom of the ma-
chine in the back ( Photo H - 2 ) and wait until
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 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 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.

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 oper-
ating correctly, reducing drying efficiency.
This machine can driven only by trained person-
nel.

DETERGENT IN THE CLEANING SOLUTION
•
Ignition key, to turn the machine on and
off.
•
Direction lever, to select forward or re-
verse move- ments.
•
Speed regulator, to select the maximum
advance- ment speed when the pedal is fully de-
pressed.
•
Brush switch, to turn on the brush rota-
tion 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)

•
Battery charge control, the sequence
of lights progressively turns off until the battery
is dis- charged. When the red light turns on, turn
