( Photo E - 6 ).
It's normal that the rear strap has to be extended
to centre the connection screws. This will bring it
under the correct tension to avoid folds on the floor
and dry correctly.

7.2.4 SQUEEGEE ADJUSTMENT

The knob screw on the squeegee support (Photo
G - 4 ) adjust the squeegee's inclination with re-
spect to the floor. The two screws on the sides, con-
nected to the rear wheels of the squeegee (Photo
G - 2 ), are to adjust the pressure of the squeegee
to the floor.
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 E - 4 ; Photo E - 2 ) to adjust the in-
clination 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.
7.2.5 SPLASH GUARD ASSEMBLY/DISAS-
SEMBLY
The splash guard is assembled to the brush plate
with a spring holder linked to the brush plate itself.
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 ACCESSORY ASSEMBLY/DISASSEMBLY

(BRUSHES, PAD DRIVERS AND ABRASIVE
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 ignition key on the control panel
is in position "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 cen-
tering flange, and turn them opposite the rotation
direction until you hear the stable "click" connec-
tion.
• 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 guide disks) 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 be-
fore 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 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
sodium hypochlorite, oxidisers, 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.
• •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 cover.
To drain the solution water tank:
• Open the valve located at the bottom of the ma-
chine in the back ( Photo D - 1 ) and wait until the
tank has been completely emptied.
• Close the drain valve.
