lift it by following the instructions provided in the
specific section.
Make sure that the ignition key on the control panel
is in OFF position.
Place the brush under the plate, taking care that
the coupling flange on the brush is under the metal
coupling of the machine.
Lower the brush plate and start the brush rotation
operating the brush motor switch and the brush
operation lever; the brush will couple automatically.
To assemble the pad holder follow the same pro-
cedure.
• 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 excessi-
vely thin abrasive disks may damage the machine
and the floor.
Regularly check the wear on these parts before
starting 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 OFF position.
While holding the brush with the hands under the
plate, turn it in the rotation direction while lowe-
ring to release it from the metal coupling on the
machine.
To disassemble the pad holder follow the same pro-
cedure.

FILLING AND DRAINING THE SO-
LUTION TANK
• The temperature of the water or the de-
tergent should never exceed 50°C.
☞ Always empty the recovery tank ( Photo N - 4)
before filling the solution tank ( Photo N - 3).
To fill the tank:
- Pour into the tank the required quantity of the
chemical product, considering the percentage indi-
cated 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.
- Pour water in the filling opening placed in the
front of the machine ( Photo H - 2, Photo N - 2 ).
Leave 2 cm between the filling opening and the
liquid level. Do not fill beyond this point!
• 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,
oxidizers, solvents or hydrocarbons) may damage
or destroy the machine.
- Follow the safety regulations specified in the re-
lative section and indicated on the detergent con-
tainer.
- Contact the machine manufacturer to obtain a
complete list of available and suitable detergents.
- 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 with its foam plug.
To drain the tank:
- Unscrew and remove the transparent cap of filter
/regulator of the cleaning solution placed in the
bottom of the tank (Photo Q - 1) and wait for the
complete emptying.
- After draining, replace and tighten the cap.
6.11
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 ( Photo N - 3) before fil-
ling it again.
In general, the recovery tank can be emptied whe-
never required, and even during intermediate pha-
ses of the work cycle.
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 ( Photo O - 1) will
stop the suction 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 holder ( Photo B
- 6, D - 6, F - 7 ) 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 how much dirt is still in the tank and, if ne-
cessary, wash it inside through the inspection hole
( Photo O - 3).
Fully tighten the drain hose with the screw plug
and hang it on the support behind the machine.
The drain hose plug must be airtight, otherwise
the subsequent pressure loss will reduce drying
efficiency.
