Charging the batteries
Take the machine to a plain surface.
Plug in batteries connector (1) placed in the rear part of
the machine, to connector (2) of the battery charger.
Never charge a GEL battery with a non-suitable recharger.
Strictly follow the instructions supplied by the batteries and
recharger manufacturer.
In order not to cause permanent damages to the batteries, it
is necessary to avoid their complete discharge, providing for
the recharging within a few minutes after batteries discharge
signal starts blinking.
Never leave batteries completely discharged even if the
machine is not used. In case of traditional batteries, please
check the electrolyte level every 20 recharging cycles and
eventually fill them up with distilled water after having carried
out a complete recharge.
Danger of gas exhalations and emission of corrosive liquids. Fire
danger: do not approach with free flames.
Squeegee assembly
With the squeegee support lowered, slide the two stud bolts
(1) placed on the upper part of the squeegee inside the
slots on the support. Block the squeegee by rotating the
lever (2) clockwise.
Insert the squeegee hose (3) into its coupling, respecting its
position as indicated in the figure.
Adjustment of the squeegee height
The squeegee must be adjusted in height depending on the
rubber wear. In order to guarantee a perfect drying during the
operation, the lower blade of the rear squeegee rubber (4)
must work slightly bent backwards (operator side) in
uniformed way in all its length.
Acting clockwise upon the two registers (5) it is possible to
increase the bending of the rubber. Acting counterclockwise it
is possible to decrease the rubber bending.
A label placed near the two registers (5) indicates rotation
sense to increase or reduce the height.
Note: The wheels of the squeegee support must be adjusted
through the registers (5) at the same height so that the
squeegee works parallel to the floor.
Adjustment of the squeegee inclination
In case of need, to increase the rubber bending in the
central part, it is necessary to tilt the squeegee rotating
counterclockwise the register (6). To increase the rubber
bending on the squeegee extremities, rotate the register
clockwise.
