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 exces-
sively 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 "0".
While holding the brushes (or the guide disks) with
the hands under the plate, turn them in the rota-
tion direction while lowering to release them from
the guide plate.

FILLING AND DRAINING THE DE-
TERGENT 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 in the back of the machine.
• Leave 7 cm between the mouth of the plug and
the liquid level. Do not fill beyond this point!
• Add the required quantity of the chemical prod-
uct, 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 deter-
gents made specifically 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
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.

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.
7.6
DRIVING THE MACHINE
Select the running direction using the Forward/Re-
verse selector.
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 selector, even while pressing on
the accelerator pedal.
