to work.
Disassembly or replacement:
Make sure that the brush plate is raised; otherwise lift
it by following the instructions provided in the specific
section.
Make sure that the ignition key on the control panel is
in position "0".
While holding the brushes (or the guide disks) with the
hands under the plate, turn them in the rotation direc-
tion while lowering to release them from the guide plate.

FILLING AND DRAINING THE DETERGENT
SOLUTION TANK
☞ The temperature of the water or the detergent
should never exceed 50°C.
☞ Always empty the detergent solution tank before fill-
ing it up.
To fill the solution tank:
- Remove the plug in the back of the machine.
- Leave some space between the mouth of the plug and
the liquid level.
- Add the required quantity of the chemical product, con-
sidering the percentage indicated by the supplier, with
reference to the full tank capacity listed on the product
sheet.
- Use only those products suitable for the floor and the
dirt to be removed.
• The machine was designed to be used with non-
foaming and biodegradable detergents made specifi-
cally for scrubber-driers. The use of other chemical
products (such as sodium hypochlorite, oxidisers,
solvents or hydrocarbons) may damage or destroy
the machine.
- Follow the safety regulations specified in the relative
section and indicated on the detergent container.
- Contact the machine manufacturer to obtain a com-
plete list of available and suitable detergents.
• Always add the detergent after filling the tank with
water to prevent foam from being created inside.
- 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 na-
tional regulations.
The user is completely responsible for ensuring compli-
ance 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 dam-
aging the machine.
The recovery tank volume is higher than the detergent
solution volume, therefore a potentially dangerous situa-
tion 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 nec-
essary, clean the interior through the inspection hole, lift-
ing 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 con-
trol 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 operating correctly, reduc-
ing drying efficiency.
This machine can driven only by trained personnel.
7.7.2
ADJUSTING THE AMOUNT OF THE DETER-
GENT 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
