3.15.3 IF THE BATTERY IS DEPLETED
WARNING
q
When checking or carrying out any operation on the bat-
tery, stop the engine and make sure that the ignition key
is in position « ».
q
The battery produces hydrogen, which may explode. Do
not use naked flames and do not smoke near the batte-
ry, and avoid producing sparks.
q
The battery electrolyte is made of diluted sulphuric acid
that may corrode the 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
gloves.
q
When removing the battery, disconnect first the earth
cable (-); when installing the battery, connect first the
positive cable (+).
q
If a tool comes into contact with the positive terminal
and with the machine structure at the same time, this
may generate sparks with consequent risk of explosion.
q
Tighten the connection terminals carefully, since false
contacts may generate sparks with consequent risk of
explosion.
