to the floor. The two screws on the sides, con-

nected to the rear wheels of the squeegee (Photo 

E - 6), 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 - 6 ) 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 attached to the brush plate 

(Photo A - 6) by interlocking on the plastic cover.

To remove the splash guard is sufficient to pull it 

down until it detaches from the plastic cover.

To replace the splash guard,push it into the bot-

tom edge of the plastic cover from one end and 

continue pushing up to the other end.

7.3 ACCESSORY 

ASSEMBLY/DISAS-

SEMBLY (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 

centering flange, and turn them opposite the rota-

tion direction until you hear the stable “click” con-

nection.



 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 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 some space between the mouth of the 

plug and the liquid level. 

•  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.

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 

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
