2.6.1 PREVENTING RISKS THAT MAY BE
DUE TO THE BATTERY
q
Electrolytic batteries contain lead and sulphuric acid, which can
cause burns. It can also corrode clothing and make holes in it.
In case of contact with battery acid, immediately wash the af-
fected part with plenty of water.
q
Battery acid may cause blindness if sprayed into the eyes.
If acid gets accidentally into your eyes, flush them immediately
with plenty of water and consult a doctor without delay.
q
If you accidentally swallow battery acid, drink a large quantity of
water or milk, beaten egg white or vegetable oil and in any case
antiacid substances like magnesia, bicarbonate, etc., and call a
doctor or a poison treatment center immediately.
q
When handling batteries, always wear safety goggles.
q
Batteries produce hydrogen, which is highly explosive and can
easily ignite with small sparks or naked flames.
q
Before any operation on the battery or before disconnecting the
cables, stop the engine, wait at least one minute, and after-
wards turn the battery main switch to OFF and extract the spe-
cific key.
q
When disconnecting the battery leads, first disconnect the neg-
ative (–) ground cable and afterwards the positive (+) one. Upon
connecting them again, connect the positive (+) cable first and
the negative (–) ground cable last.
q
Avoid short-circuiting the battery terminals through any contact,
even if accidental, with metal objects or tools or by inverting
them.
q
Tighten the battery terminals securely. Loose terminals may
generate sparks and may cause the battery to explode.
q
Install the battery securely to the determined place.
q
When removing the battery cables, first turn the starting switch
to the OFF position, wait over one minute, then turn the battery
disconnect switch to the OFF position and take out the battery
disconnect switch key. Then begin the cable removal at the
ground (negative "-") cable side. When installing the battery ca-
bles, be sure to begin with the positive (+) cable side and finish
at the ground cable side.
