D-4 ELECTRICAL SYSTEM
DANGER
All maintenance interventions must be carried out
with engine stopped, parking brake engaged,
working attachments on the ground and gearbox
lever in neutral.
DANGER
When raising a component for maintenance
purposes, secure it in a safe way before carrying
out any maintenance.
DANGER
Any intervention on the electrical system unless
performed by authorized personnel, is expressly
forbidden.
D-4.1 BATTERY
•
Check the electrolyte level every 250 working
hours; if necessary, add distilled water.
•
Ensure the fluid is 5÷6 mm above the plates and the
cell levels are correct.
•
Check the cable clips are well secured to the
battery terminals. To tighten the clips, always use
a box wrench, never pliers.
•
Protect the terminals smearing them with pure
vaseline.
•
Remove the battery and store it in a dry place,
when the machine is not used for a long time.
DANGER
•
Battery electrolyte contains sulphuric acid. It
can burn you if it touches your skin and eyes.
Always wear goggles and protective gloves,
and handle the battery with caution to prevent
spillage. Keep metal objects (watch straps,
rings, necklaces) clear of the battery leads,
since they can short the terminals and burn
you.

Before disconnecting the battery, set all
switches within the cab to OFF.
To disconnect the battery, disconnect the ne-
gative (-) lead from the frame earth first.
To connect the battery, connect the positive (+)
lead first.
Recharge the battery far from the machine, in a
well-ventilated place.
Keep out of items which can produce sparks, of
naked flames or lit cigarettes.
Do not rest metal objects onto the battery. This
can result in a dangerous short especially during
a recharge.
Because the electrolyte is highly corrosive, it
must never come in contact with the frame of
the handler or electric/electronic parts. If the
electrolyte comes in contact with these parts,
contact the nearest authorised assistance
centre.
