2.6 BATTERY

2.6.1 PREVENTING RISKS THAT MAY BE
DUE TO THE BATTERY
Electrolytic batteries contain sulphuric acid that can quickly
burn the skin and corrode clothes making holes in the fabric. If
you spill acid on yourself, immediately rinse the involved area
with plenty of water.
Battery acid may cause blindness if splashed into the eyes.
If acid gets accidentally into your eyes, flush them immediately
with plenty of water and consult a doctor without delay.
If you accidentally swallow some 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 poisoning prevention center immediately.
When handling batteries, always wear safety goggles.
Batteries generate hydrogen. Hydrogen 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.
2.6.2 STARTING WITH BOOSTER CA-
BLES
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.
Disconnect 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.
