the recovery tank before filling it again.
In general, the recovery tank can be emptied when-
ever 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 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 the quantity of residual dirt in the tank and, if
necessary, clean the interior through the inspection
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 han-
dles 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/Re-
verse 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 for-
ward/reverse lever, even while pressing on the accel-
erator pedal.

WORK METHOD
6.7.1. PREPARATION AND WARNINGS
Remove any loose solid residue from the surface to be
treated (using suitable tools, such as vacuum clean-
ers, sweepers, etc.). It this is not done, the solid dirt
might prevent the squeegee from operating correctly,
reducing drying efficiency.
This machine can driven only by trained personnel.
6.7.2. ADJUSTING THE AMOUNT OF THE
DETERGENT IN THE CLEANING SOLUTION
The adjustment of the amount of detergent to be
used in the cleaning solution is carried out through
the push selector on the control panel (Photo N - 3).
Pressing the selector multiple times will increase the
amount of detergent dispensed; the dilution of the
detergent dispensed is displayed on the control panel
(Photo N - 7) through progressive levels highlighted in
the graphic symbol (Photo O).
The percentage of dilution of the detergent varies
depending on the amount of clean water delivered,
adjustable through the control lever (Photo H - 1);
when the clean water outflow is half of the total pos-
sible amount, the percentage of dilution is shown in
Photo O - 1; when the clean water outflow is set on
the full amount the dilution percentage is shown in
Photo O - 2.
6.7.3. DIRECT SCRUBBING OR FOR SLIGHTLY
DIRTY SURFACES
Scrubbing and drying in a single pass.
Prepare the machine as previously described.
Select the forward direction using the direction lever.
Insert and turn the key.
Activate the suction motor, the brush motor and the
detergent solution supply.
Lower the brushes and the squeegee.
Use the detergent adjustment lever to regulate the
solution outlet flow (depending on advancement
speed).
Lightly press the advancement pedal and check that
all systems are working.
Fully depress the accelerator to increase the work
speed. Adjust the maximum advancement speed and
the detergent solution flow as required.
The steering wheel is similar to a car steering wheel:
it can be used to turn the machine around itself by
steering all the way to one side.
To avoid damage to the surfaces being treated, the
brush motor will stop automatically about 2 seconds
after the advancement pedal has been completely
released.
• Remember to lift the squeegee before driving
reverse to avoid damaging it.
☞ Never use the machine without the detergent solu-
tion: the floor might be damaged.
6.7.4. INDIRECT SCRUBBING OR FOR VERY
DIRTY SURFACES
Scrubbing and drying in various passes.
Prepare the machine as previously described.
