10. During the first stretches check that the 

squeegee adjustment guarantees a perfect drying 

action and that the detergent solution flow is 

appropriate. It has to be sufficient to wet the floor 

uniformly. Always consider that the correct quantity 

of solution detergent depends on type of floor, 

dirtiness and machine speed.

FORWARD MOVEMENT

The traction of the machine is given through an 

electronically controlled motor.

To move the machine, switch on the key (1) and 

then rotate the levers drive control (2) placed on the 

handle bar, in forward you obtain the forward drive, 

in reverse the backwards movement is obtained. 

The control acts in a progressive way, therefore it 

is possible to graduate the speed depending on 

each requirement rotating the lever whatever it 

is necessary. During reverse motion the speed is 

reduced.

Moving the machine backwards, make sure that the 

squeegee is lifted.

SPEED ADJUSTMENT

Two values of the maximum drive working speed in 

forward movement can be chosen.

Set the wanted speed through the speed selection 

switch (1).

WORKING BRAKE

To stop the machine during normal working 

situation, it is sufficient to release the levers drive 

control (1), as the machine is equipped with an 

electronic braking system. The base and the 

detergent solution flow stop automatically.

EMERGENCY BRAKE

In case of an emergency, an immediate stop can be 

obtained acting upon the lever of the emergency 

and parking brake (1) by pushing it downwards.

This control blocks the machine immediately. 

The emergency brake functions also as a parking 

brake. To start again to work, release the lever by 

unblocking the parking button on the lever itself 

and act again upon the levers drive control.

ADJUSTMENT OF THE BASE PRESSURE

Through the register (1) it is possible to adjust the 

pad pressure on the cleaned surface.

By turning the knob clockwise, the pressure 

increases, rotating it counterclockwise, the pressure 

decreases.

This device allows a more efficient cleaning action 

also on very difficult and dirty surfaces.
