WORK METHOD

6.14.1

PREPARATION AND WARNINGS

Remove any loose solid residue from the surface
to be treated (using suitable tools, such as vacuum
cleaners, sweepers, etc.). It this is not done, the
solid dirt might prevent the squeegee from opera-
ting correctly, reducing drying efficiency.
Only trained personnel can drive this machine.
6.14.2 BATTERY
TROLS
The sequence of lights of the battery charge con-
trol ( Photo C - 1 ) progressively turns off until the
battery is discharged . When the red light turns
on, switch off the brush motor, close the detergent
solution outlet, finish drying the small residual moi-
sture and go to the battery charging area to charge
the battery.
• The batteries may be irreparably damaged if
the residual charge level drops too low (see the
battery operating manual). Do not force the battery
discharge beyond the safety limits, turning the key
off and on or in any other manner.
6.14.3 DIRECT
SLIGHTLY DIRTY SURFACES
Scrubbing and drying in a single pass.
Prepare the machine as previously described and
