BATTERIES
PB-Acid batteries
Carry out maintenance operations in accordance
with the manufacturer's instructions and with all
the other instructions provided in this manual.
Exposing the element plates (not completely im-
mersed in the acid solution) will lead to rapid oxida-
tion and irreparably reduce the element's operating
capacities.
An overflowing acid solution may corrode the ma-
chine.
Use battery chargers recommended by the manu-
facturer and, in any case, those that are suitable
for the type of battery to be charged.
Always charge batteries in well-ventilated rooms:
there is an explosion risk!
The use of gel or maintenance-free batteries is hi-
ghly recommended.
GEL batteries
Carry out maintenance operations in accordance
with the manufacturer's instructions and with all
the other instructions provided in this manual.
Use only those battery chargers recommended by
the manufacturer.
7.7
THERMAL BREAKERS
The machine is equipped with electric protection
devices on the main operating components to
avoid costly malfunctions.
Thermal breakers are installed to protect the drive
motor wherever foreseen and the brush motor.
When one of these breakers trips automatically,
the disabled function can be reactivated by fully
depressing the button of the breaker.
When the thermal breakers trip, especially when
the machine is used during the first few weeks, it
might not be caused by actual machine malfun-
ctions. However, a specialized technician should
check the device if the relative breaker continues
to trip.

PERIODIC MAINTENANCE
For all the operations described herein, refer to the
instructions and detailed warnings in the relative
sections.
