3.7.4 PRECAUTIONS TO BE TAKEN WHEN

CONDITIONS
q
When carrying out digging operations in water, if water gets on
the pins of the work equipment, always add grease to the
bucket articulations (1), (2), (3), (4) and (5) before work.
q
When carrying out heavy duty digging and deep digging
operations, always add grease to the bucket articulations (1),
(2), (3), (4) and (5) (total: 5 points) before work.
After greasing, operate the bucket more than once, then add
grease again.
3.7.5 IF THE BATTERY IS DOWN
WARNING
q
It is dangerous to charge the battery when it is installed in
the machine. Always remove it before recharge.
q
Before carrying out any work on the battery, stop the
engine and turn the ignition key to position OFF.
q
The battery produces hydrogen, which may explode. Do
not smoke and avoid producing sparks near the battery.
q
The battery electrolyte is made of diluted sulphuric acid
that may corrode clothes and even the skin; in case of
contact with this fluid, immediately rinse the involved part
with plenty of water. If the acid gets into the eyes,
immediately rinse with plenty of water and consult a doctor
without delay.
q
When working on the battery, always wear goggles and
rubber gloves.
q
When removing the battery, disconnect the earth cable (-)
first. When installing the battery, connect the positive
terminal (+) first.
If a tool touches the positive terminal and the frame of the
machine at the same time, sparks may be generated, thus
causing an explosion hazard.
q
Carefully tighten the connection terminals, since false
contacts may generate sparks with consequent risk of
explosion.
q
The accumulation of oxide around the terminals causes the
battery to discharge. Clean the terminals carefully and
cover them with a thin film of grease before installation.
