4.8.8.c CHECKING THE BATTERY ELECTROLYTE
LEVEL
WARNING
q
Carry out this check with the machine parked on level
ground.
q
Check the level only after stopping the engine and if
necessary add distilled water only before starting work.
q
Always wear safety goggles and waterproof gloves.
q
To prevent gas explosions, do not use naked flames, do
not smoke and avoid producing sparks due to short
circuits.
q
The battery electrolyte is dangerous; in case of contact
with the eyes or skin, rinse with plenty of water and consult
a doctor without delay.
To reach the battery (1), release the lock (2), loosen the screws
(3) and remove the upper cover (4).
Use a 17 mm hex wrench.
The electrolyte level in each cell must be about 6 mm above the
plate edge; if necessary, remove the cell caps and top up using
exclusively distilled water.
If, on the contrary, the level is low because some fluid has been
spilled, add electrolyte with concentration suitable for the ambient
temperature (see "3.10.3 BATTERY").
NOTE
q
When adding distilled water or electrolyte, do not exceed the
level indicated. This would shorten the service life of the battery
and may cause the electrolyte to overflow.
Put back the upper cover (4) and lock the door (5).
IMPORTANT
q
It is advisable to add distilled water before starting work, in
order to prevent if from freezing.
q
Before putting back the cell caps, make sure that the
breather holes are not clogged.
q
Make sure that the terminals and connection cables are not
oxidized; if necessary, clean them and cover them with
anti-oxidation grease.
