For models equipped with parking brake: press 
pedal 

A

 to engage the brake.

Press pedal 

B

 to disingage it.

Drop the brushes roughly side by side in front of 
the machine; the actual position does not matter.

Switch the machine on by turning the key switch a 
quarter of turn clockwise. Wait momentarily until 
the multifunction display lights showing the 
battery voltage.

PREPARATION FOR USE

Drive the machine forward by holding the hand-
grips, then rolling the thumb wheels forward until 
the machine moves.
In the event of a temporary stop (releasing thumb 
wheels) the automatic switch-off of the all functions 
will occur (AUTOPOWER-OFF).

Turn the thumb wheels in order to restart the 
normal operation; all the functions will restart 
automatically
(AUTOPOWER-ON).

NOTE

: for all versions of model 

AW445 

and 

(brush driven model) the rotation of the brush will 
make the forward displacement of the machine 
easyer. On the same model the “AUTOPOWER-
OFF”/“AUTOPOWER-ON” function is not 
available.

The following adjustments can be done on the 
machine: increase or reduction of the pressure of 
the brushes on the floor by means of the 
dedicated rotating knob: the required pressure 
will depend on the kind of floor and dirt to be 
scrubbed.

NOTE

: Set the pressure to the minimum possible 

value, consistantly with the kind of dirt to be 
cleaned: this will increase the battery working 
time.

Increase or reduce of the pressure of the 
squeegee on the floor by means of the dedicated 
knob: again the required pressure will be different 
depending on the kind of floor to be dryed.
