battery charger ( Photo L - 2 ) and to the mains 

power.

On switching on the battery charger will check the 

battery voltage and decide whether to start the 

charging process. If the battery is not connected 

to the battery charger, the red LED will flash. If the 

result of the test is positive after 1 second the char-

ging of the battery can start, with the red LED on.

The progress of the charging process is shown by 

three LED’s: red, yellow and green, as in the whole 

range of the battery chargers.

The green LED shows the end of the charging or 

the last phase in case of deep charging process; in 

the former case, the relay is opened to disconnect 

galvanically the battery from the battery charger.

•

For further information refer to the use and sa-

fety manual of the battery charger provided by the

manufacturer.

If the machine is equipped with Pb-Acid batteries, 

charge only in a well-ventilated area, lift the supe-

rior cover and open the battery plugs.

•

Follow the steps indicated in the battery ma-

nufacturer’s operating and safety manual (see the

battery maintenance section).

If the machine is equipped with GEL batteries

(maintenance free), follow the instructions indica-

ted here below.

If the machine is used regularly:

Always keep the batteries connected to the battery

charger when the machine is not being used.

If the machine is not used for extended time pe-

riods:

Charge the battery during the night after the last

work period, and then disconnect the battery from

the battery charger.

Charge the battery during the night before using

the machine again.

Intermediate or incomplete charging while working

should be avoided.

If the machine is equipped with Pb-Acid batteries, 

use a hydrometer to check the element liquid in-

tensity on a regular basis: if one or more elements 

are discharged and the others fully charged, the 

battery has been damaged and should be replaced 

or repaired (refer to the battery service manual).

Close the element plugs and lower the superior 

cover.

SQUEEGEE ASSEMBLY

Slightly screw the two knobs ( Photo M - 6 ) into 

the squeegee body and insert the squeegee into 

the slots situated on the squeegee support.

Screw the two knobs ( Photo M - 6 ) in order to 

secure the squeegee to the support.

Firmly insert the suction hose ( Photo M - 3 ) into 

the pipe in the squeegee body. 

6.5 

SQUEEGEE DISASSEMBLY

Disconnect the suction hose from the squeegee 

body.

Unscrew the two knobs ( Photo M - 6 ) that secure 

the squeegee to its support and pull the squeegee 

to free it.

6.6 

SQUEEGEE BLADES DISASSEMBLY 

/ ASSEMBLY

Disassemble the squeegee from its support (see 

6.5)

Unscrew the knobs ( Photo M - 4, Photo M  - 6 

) placed on the squeegee body and apply some 

pressure on their bolts in order to push out the 

plastic support of the squeegee blades from the 

squeegee body.

Tear off the rubber blades from the plastic support.

Assemble the new blades on the plastic support by 

the means of the plastic pins that have to be fixed 

in the holes placed the blades.

Push the plastic support of the squeegee blades 

into the squeegee body and screw the knobs 

( Photo M - 4, Photo M - 6 ) to secure it to the 

squeegee body.

Reassemble the squeegee to its support (see 6.4).

6.7 

SQUEEGEE ADJUSTMENT

The knob screw on the squeegee support ( Photo 

M - 7) adjusts the squeegee’s inclination with re-

spect to the floor. The two red knobs on the sides, 

connected to the rear wheels of the squeegee ( 

Photo M - 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), the knobs ( 

Photo M - 2, Photo M - 7 ) can be used 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 optimize 

drying.

6.8 

SPLASH GUARD ASSEMBLY/ DI-

SASSEMBLY

The splash guard is attached to the brush plate 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 bottom 

edge of the plastic cover from one end and con-

tinue pushing up to the other end.

6.9 

BRUSH ASSEMBLY / DISASSEMBLY

•

Never use the machine if the brush or the pad

holder with abrasive pad is not perfectly installed.

Assembly:

Make sure that the brush plate is raised; otherwise
