SCRUBBING WITH DRYING

To perform a scrubbing and drying program, proceed as follows:

1.  Make all the checks listed in “

PREPARING TO WORK

”.

2.  Go to the driving position, behind the machine.

3. 

Turn the main switch (1) to "I", making a quarter turn of the key in the direction of the arrow 

(

Fig.1

). 

4.  Lower the brush head body and press the “BRUSH HEAD CONTROL” button (2) on the control 

panel (

Fig.2

).

NB

:

 

as soon as the button (2) on the control panel is pressed, the green LED (3) (“BRUSH 

HEAD BODY WORK POSITION”) will switch on (

Fig.2

).

5.  Lower the squeegee body and turn the squeegee control lever (4) in the direction of the arrow 

(

Fig.3

). The lever is located on the back of the machine.

6.  When the dead man's lever (5) is pressed, the machine will begin to move. The lever is located 

underneath the control handlebars (

Fig.4

).

NB

:

 the brush head body will only begin to descend to its working position when the dead 

man's lever has been pressed.

NB

:

 the gearmotor will only begin functioning, and the solenoid valve will only begin dispensing 

detergent solution, when the brush head body is in its working position.

DRYING

To perform a drying program, proceed as follows:

1.  Make all the checks listed in “

PREPARING TO WORK

”.

2.  Go to the driving position, behind the machine.

3. 

Turn the main switch (1) to "I", making a quarter turn of the key in the direction of the arrow 

(

Fig.1

). 

4.  Lower the squeegee body and turn the squeegee control lever (2) in the direction of the arrow 

(

Fig.2

). The lever is located on the back of the machine.

5.  When the dead man's lever (3) is pressed, the machine will begin to move. The lever is located 

underneath the control handlebars (

Fig.3

).

NB

:

 the vacuum motor will only begin to work when the squeegee body is in contact with the 

floor.

SCRUBBING WITHOUT DRYING

To perform a scrubbing only program, proceed as follows:

1.  Make all the checks listed in “

PREPARING TO WORK

”.

2.  Go to the driving position, behind the machine.

3. 

Turn the main switch (1) to "I", making a quarter turn of the key in the direction of the arrow 

(

Fig.1

). 

4.  Lower the brush head body and press the “BRUSH HEAD CONTROL” button (2) on the control 

panel (

Fig.2

).

NB

:

 

as soon as the button (2) on the control panel is pressed, the green LED (3) (“BRUSH 

HEAD BODY WORK POSITION”) will switch on (

Fig.2

).

5.  When the dead man's lever (4) is pressed, the machine will begin to move. The lever is located 

underneath the control handlebars (

Fig.3

).

NB

:

 the brush head body will only begin to descend to its working position when the dead 

man's lever has been pressed.

NB

:

 the gearmotor will only begin functioning, and the solenoid valve will only begin dispensing 

detergent solution, when the brush head body is in its working position.

The drying without scrubbing operation should only be 

carried out if the machine was previously used to 

carry out a scrubbing without drying operation.

REGULATING THE DETERGENT SOLUTION

To adjust the amount of detergent solution on the brush, proceed as follows:

1.  Make sure the detergent solution tap is fully open, rotating the knob (1) in the direction of 

the arrow (

Fig.1

). As the knob is rotated, the flow of detergent in the machine water circuit is 

increased.

2.  By pushing the dead man's lever (2) the brush motor will start operating and the solenoid valve 

will distribute detergent solution to the brush (

Fig.2

).

3. 

During the first few meters check that the amount of solution is sufficient to wet the floor, but not 

excessive to exit the splash guard.

4.  If the amount of solution that comes out is not right, use the “+” and “-” buttons (3) on the control 

panel to adjust it (

Fig.3

).

NB

:

 

the flow of detergent solution on the brush can be adjusted at 4 levels from 0 to 3. The 

level can be seen with the symbol (4) on the control display (

Fig.4

).

REGULATING THE FORWARD SPEED

This machine is equipped with electronic traction control. To adjust the forward speed, proceed as 

follows:

1. 

Turn the main switch (1) to "I", making a quarter turn of the key in the direction of the arrow 

(

Fig.1

).

2.  Press the dead man's levers (2) underneath the control handlebars (

Fig.2

).

3.  Adjust the forward speed using the “+” and “-” buttons (3) on the control panel (

Fig.3

).

NB

: the forward brush speed can be adjusted at 4 levels from 0 to 3. The level can be seen 

with the symbol (4) on the control display.

NB

: the machine will not start moving (either forwards or backwards) if the level of (4) is zero.

NB

: the machine forward speed can also be adjusted by regulating the potentiometer in the 

control panel. To do this, press the dead man's lever (2) to the required degree. The more you 

press, the higher the speed (within the limits of the level selected beforehand).

REVERSE GEAR

This machine is equipped with electronic traction control. To reverse, proceed as follows:

1.  Lift the brush head body and press the “BRUSH HEAD CONTROL” button (1) on the control 

panel (

Fig.1

).

NB

:

 

as soon as the button (1) on the control panel is pressed, the green LED (2) (“BRUSH 

HEAD BODY WORK POSITION”) will switch off (

Fig.1

).

NB

:

 

if the brush head body is left in contact with the floor, the gearmotor will continue 

functioning but the solenoid valve will stop dispensing detergent solution on the brush.

2.  Raise the squeegee body and turn the squeegee control lever (3) in the direction of the arrow 

(

Fig.2

). The lever is located on the back of the machine.

3.  Press the “REVERSE ACTIVATION - DEACTIVATION” button (4) on the control handlebars 

(

Fig.3

).

NB

:

 

as soon as the button (4) on the control panel is pressed, the green LED (“REVERSE 

ACTIVE”) will switch on.
