indications for the maintenance and daily
recharge of the batteries. All installation and
maintenance operations must be executed
by specialized staff, using suitable protection
accessories.
BATTERY RECHARGER
Be sure that the battery recharger is suitable
for the installed batteries both for their
capacities and type (lead/acid or GEL and
equivalent).
ON-BOARD BATTERY RECHARGER
The machine is equipped with the on-
board battery recharger. Please refer to the
manufactures instructions on the use of the
charger. The battery recharger is connected
directly to the battery poles. During the
recharging operations a device is activated

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.
BATTERIES DISPOSAL
It is compulsory to hand over exhaust batteries,
classified as dangerous waste, to an authorized
institution according to the current laws.

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 a uniformed way in all its
length.
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.
Acting clockwise upon the two registers (5) it is
possible to increase the bending of the rubber.
BATTERIES CHARGE LEVEL INDICATOR
When switching on, the signal lamp of the
battery charge level (2) will come on. When
the signal lamp is in green color it means that
the battery charge level is sufficient for the
functioning of the machine. If the signal lamp
is in red color it means that the battery charge
level is insufficient for the functioning of the
machine and it is necessary to recharge
the batteries (see under "BATTERIES
CHARGING”).

BRISTLES
THICKNESS
Thicker bristles are more rigid and must be used on smooth floor or
floor with small joints. On irregular floors with deep joints or relieves,
it is recommended to use softer bristles which penetrate more easily
and deeper. Please be aware that when brush bristles are worn out and
therefore too small, they become rigid and unable to penetrate and clean
deeper. This may also happen with thicker bristles creating brush vibration.
PAD HOLDER It is equipped with anchor points which permit the blocking of the abrasive
pad during work. The pad is recommended to clean smooth floors.
