GENERAL FEATURES
Your telescopic handler is equipped with a 12 volt electrical equipment with the negative pole grounded.
BATTERY
The battery of your machine is placed inside engine compartment and it is
equipped with a manual cut-off switch that keeps it charged when the machine is
not set in motion for a prolonged period of time.
NOMENCLATURE OF THE BATTERY COMPARTMENT:
A) Battery
B) Positive pole
C) Negative pole
D) Manual cut-off switch
E) Main fuse of the electrical equipment (80A)
F) Engine pre-heater fuse (80A)
G) Glow plugs relay
The main features of the battery are listed below:
•
Capacity in 20 hours = 100 Ah
• Cold start current = 850 A
• Specific weight: a fully charged battery shall have an electrolyte with a
specific weight of 1.260. If this value is lower than 1.215, the battery needs to
be charged.
The specific weight of the electrolyte may only be different if you work in
countries having either a tropical climate or a cold climate.
In a tropical climate the readout for a fully charged battery shall be equal to
1.225.
In a cold climate the readout for a fully charged battery shall be equal to
1.280.
•
Inspection of the electrical equipment: regularly check the condition of cable
harnesses and electrical connections.
WARNING! All inductive loads (electric motors, solenoid valves, etc.) are protected by internal diodes in order
to avoid current peaks when switched off, for this reason never swap the input polarities.
• sulphuric acid:
WARNING! Sulfuric acid in batteries is a poson and could cause severe burns. Avoid contact with skin, eyes,
and clothes. When you work around batteries, protect eyes and face from battery fluid and explosion.
If you accidentally come into contact with the sulphuric acid contained in the battery, proceed as follows:
External measures:
- wash your skin with water
- rinse your eyes for 15 minutes
- seek immediate medical advice
Internal measures:
- drink plenty of water or milk
- soon afterwards drink milk of magnesia, beaten eggs, or vegetable oil
- seek immediate medical advice
IMPORTANT! Before carrying out any work on the electrical equipment disconnect the negative cable from the
battery. The gases contained in the battery may explode. Keep cigarettes, sparks and flames away from the battery.
Never use connection cables and never work on the connections if you are not familiar with the correct procedure to
be followed.
When you either charge a battery or use a battery in an enclosed room, make sure that the room is well ventilated.
Keep batteries away from children.
Make sure that the vent plugs are tightened correctly, and check the electrolyte level at regular intervals.
