•
Electrolytic batteries contain sulphuric acid which can cause
burns. It can also corrode clothing and make holes in it. If you
get splashed with battery acid, immediately wash the affected
part with plenty of water.
•
Battery acid may cause blindness if it comes into contact with
the eyes.
If acid accidentally gets into your eyes, wash them immediately
with plenty of water and consult a doctor right away.
•
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.;. call a
doctor or a poison treatment center immediately.
•
Always wear safety goggles when working on batteries.
•
Batteries produce hydrogen, which is highly explosive and can
be easily ignited with small sparks or naked flames.
•
Before working with batteries, stop the engine and remove the
ignition key.
•
Avoid short-circuiting the battery terminals through accidental
contact with metal objects or tools or through the inversion of
the terminals.
•
Tighten the battery terminals securely. Loose terminals may
generate sparks and even cause the explosion of the battery.

When starting the machine with booster cables, always wear
safety goggles.
•
When starting the engine by means of another machine, avoid
any contact between the two machines.
•
Be sure to connect the positive cable (+) first and then the neg-
ative or earth cable (-) when connecting the booster cables. Dis-
connect first the negative or earth (–) cable and then the
positive cable (+) after the start.
•
Connect the batteries in parallel: positive to positive and nega-
tive to negative.
•
When connecting the earth cable to the frame of the machine to
be started, operate as far as possible from the battery.
