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 machine.
Use battery chargers recommended by the manufac-
turer 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!
Always charge batteries in well-ventilated rooms,
there is a risk of explosion!
The use of gel or maintenance-free batteries is highly
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.
If the batteries are not used, in either case, for an ex-
tended period of time, disconnect them and restore
the charge within the time limits specified for the
type of battery used (generally and as a precaution,
no more than 3 months for Pb-acid/GEL/AGM batter-
ies, 6 months for Li-ion batteries).
The manufacturer accepts no liability for damage to
batteries caused by failure to follow this procedure.

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 depress-
ing 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 malfunctions. How-
ever, 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 in-
structions and detailed warnings in the relative sections.

RECOMMENDED SPARE PARTS
You'll always be able to use your machine as effi-
ciently as possible by maintaining a stock of the most
common consumable materials and by scheduling
routine and extraordinary maintenance. Contact your
dealer for a list of these spare parts.
