2.6 BATTERY
2.6.1 PREVENTING RISKS THAT MAY BE
DUE TO THE BATTERY
q
Electrolytic batteries contain 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 affected 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 working on the battery, stop the engine and remove the
ignition key.
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.
2.6.2 STARTING WITH BOOSTER CABLES
q
When starting the machine with booster cables, always wear
safety goggles.
q
When starting the engine by means of another machine, avoid
any contact between the two machines.
q
When connecting the booster cables, make sure to connect the
positive cable (+) first and then the negative or earth cable (–).
After the start, disconnect first the negative or earth cable (–)
and then the positive cable (+).
q
Connect the batteries in parallel: positive to positive and nega-
tive to negative.
q
When connecting the earth cable to the body of the machine to
be started, operate as far as possible from the battery. (See
"3.7.5 IF THE BATTERY IS DOWN").
q
Do not attempt to start the engine by short-circuiting the starter
terminals (see "2.8.14 PRECAUTIONS CONCERNING THE
STARTER").
