8.6 BATTERIES
8.6.1 PB-ACID
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 immer-
sed in the acid solution) will lead to rapid oxidation and
irreparably reduce the element's operating capacities.
An overflowing acid solution may corrode the machine.
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.

8.7 FUSES AND THERMAL BREAKERS
The machine is equipped with electric protection
devices on the main operating components to avoid
costly malfunctions.
Thermal cutouts 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 de-
pressing the breaker that tripped.
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 specialised technician should
check the device if the relative breaker continues
to trip.
