relative section and indicated on the detergent
container.
• Contact the machine manufacturer to obtain a
complete list of available and suitable detergents.
• •Always add the detergent after filling the tank
with water to prevent foam from being created in-
side.
• Do not leave the water hose unattended and
insert 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
machine in the back ( Photo D - 1 ) 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 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
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 hi-
ghlighted in the graphic symbol (Photo O).
The percentage of dilution of the detergent varies
depending on the amount of clean water delive-
red, adjustable through the control lever (Photo H
- 1); when the clean water outflow is half of the
total possible amount, the percentage of dilution
is shown in Photo O - 1; when the clean water
outflow is set on the full amount the dilution per-
centage is shown in Photo O - 2.
7.7.3
DIRECT
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.
