8.7 BATTERIES
8.7.1 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
immersed in the acid solution) will lead to rapid
oxidation and irreparably reduce the element’s
operating capacities. An overflowing acid solu-
tion may corrode the machine. Use battery charg-
ers recommended by the manufacturer 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
highly recommended.
8.7.2 GEL
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.

For all the operations described in the following
scheduled maintenance table, refer to the instruc-
tions and detailed warnings in the relative sec-
tions.
8.9 RECOMMENDED SPARE PARTS
You’ll always be able to use your machine as ef-
ficiently as possible by maintaining a stock of
the most common consumable materials and by
scheduling routine and extraordinary mainte-
nance. Contact your dealer for a list of these spare
parts.
