SEMBLY
- Unscrew the 2 screws of the splash guard (Foto

ACCESSORY ASSEMBLY/DISASSEM-
BLY (BRUSHES, PAD DRIVERS AND ABRASI-
VE DISKS)
• Never use the machine if brushes or pad drivers
and abrasive disks are not perfectly installed.
Assembly:
Make sure that the brush plate is raised; otherwise lift
it by following the instructions provided in the specific
section.
Make sure that the main switch on the control panel
is set to OFF "0" .
Bring the brushes (or the guide disks equipped with
abrasive disks) near the connections, under the brush
plate; lift them, bring them through the centering
flange, and turn them opposite the rotation direction
until you hear the stable "click" connection.
• Do not allow the length of the rows of brushes to
become lower than 1 cm.
• Do not allow the thickness of the abrasive disks to
become less than 1 cm.
Working with excessively worn brushes or excessively
thin abrasive disks may damage the machine and the
floor.
Regularly check the wear on these parts before start-
ing 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 main switch on the control panel
is set to OFF "0" .
While holding the brushes (or the guide disks) with
the hands under the plate, turn them in the rotation
direction while lowering to release them from the
guide plate.

FILLING AND DRAINING THE DETER-
GENT SOLUTION TANK
☞ The temperature of the water or the deter-
gent should never exceed 50°C.
☞ Always empty the detergent solution tank before
filling it up.
To fill the solution tank:
- Remove the plug on the machine (Foto A-9*) .
- Leave some space between the mouth of the plug
and the liquid level.
- Add the required quantity of the chemical product,
considering 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 specifically for scrubber-driers. The use
of other chemical products (such as sodium
hypochlorite, oxidisers, solvents or hydrocar-
bons) may damage or destroy the machine.
- Follow the safety regulations specified in the rela-
tive 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:
- Unscrew the plug placed in the machine lower area
(Foto C-23*) and wait for the complete tank empty-
ing.
- After the emptying operation, screw and fully tighten
the drain plug.
7.10
DRAINING THE RECOVERY TANK
The dirty water must be drained in accordance with
national regulations.
The user is completely responsible for ensuring com-
pliance 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 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 danger-
ous situation for the suction motor should never occur.
In any case, a safety float (Foto F-43*) 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.
