4.9.1.b BATTERY ELECTROLYTE LEVEL CHECK
WARNING
q
Carry out this check with the machine parked on level ground.
q
Check the level only when the engine is stopped and, if necessary, add distilled water only before start-
ing the operations.
q
Always wear protective 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.
IMPORTANT
q
It is advisable to add distilled water just 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.

Check that the terminals and connection cables are not rusted; if necessary, clean and protect them with
antioxidant grease.
