When the squeegee is perfectly adjusted, the rear
squeegee blade, sliding as it moves, bends in all
points forming an angle of 45° with the floor.
As the machine operates (advances), it is possible
to operate on the inclination knob and pressure
screws ( Photo D - 1 ; Photo D - 3 ) to adjust the
inclination and pressure of the squeegee blades on
the floor.
Squeegee drying must be uniform along the entire
drying line: damp patches mean that drying is in-
sufficient; turn the adjustment knobs to optimise
drying.

SPLASH GUARD ASSEMBLY/DISAS-
SEMBLY
The splash guard is assembled to the brush plate
with a spring holder linked to the brush plate itself
(Photo I - 1 ).
To disassemble the splash guard simply detach the
spring holder and pull the splash guard.
To reassemble, fix the splash guard in the brush
plate, and then hook the steel cable to one side of
the plate and the spring holder to the other side of
the brush plate.
7.3 BRUSH ASSEMBLY / DISASSEMBLY
!
(
) Never use the machine if brushes or scrapers
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 ignition key on the control panel
is in position "0".
Bring the brushes (or the pad drivers equipped with
abrasive pads) near the connections, under the
brush plate; lower the washing plate and start the
brushes turning: the brushes/discs couple automa-
tically;
!
(
) 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 "0".
While holding the brushes (or the pad drivers) with
the hands under the plate, turn them in the rotation
direction while lowering to release them from the
guide plate.
7.4 FILLING AND DRAINING THE DETER-
GENT SOLUTION TANK
☞
(
) The temperature of the water or the de-
tergent should never exceed 50°C.
• Always empty the detergent solution tank before
filling it up.
To fill:
• Remove the plug in the front of the machine .
• Leave 2 cm between the mouth of the plug and
the liquid level. Do not fill beyond this point!
• Add the required quantity of the chemical pro-
duct, considering the percentage indicated by the
supplier, with reference to the full tank capacity li-
sted 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 so-
dium hypochlorite, oxidisers, solvents or hydrocar-
bons) 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.
☞
(
) 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 in-
sert it completely into the tank: the hose might
move and get sensitive parts of the machine wet.
Close the tank with its plug...
To drain:
• Unscrew the cock.
• Close the drainage plug firmly.
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 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 turns off the suc-
tion 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:
