2.6 BATTERY
2.6.1 SAFETY PRECAUTIONS FOR
WORK ON BATTERIES
Electrolytic batteries contain sulphuric acid which can cause
q
burns. It can also corrode clothing and make holes in it. If
you inadvertently splash battery acid on yourself or on so-
meone else, immediately wash the affected part with plenty
of water.
Battery acid may cause blindness if it comes into contact
q
with the eyes.
If acid accidentally gets into your eyes, wash them immedia-
tely with plenty of water and consult a doctor right away.
If you accidentally swallow battery acid, drink a large quanti-
q
ty 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.
q
Batteries produce hydrogen, which is highly explosive and
q
can be easily ignited with small sparks or naked flames.
Before working with batteries, stop the engine and remove
q
the ignition key.
Avoid short-circuiting the battery terminals through acciden-
q
tal contact with metal objects or tools or through the inver-
sion of the terminals.
Tighten the battery terminals securely. Loose terminals may
q
generate sparks and even cause the explosion of the batte-
ry.
2.6.2 STARTING WITH BOOSTER
CABLES
When starting the machine with booster cables, always wear
q
safety goggles.
When starting the engine by means of another machine,
q
avoid any contact between the two machines.
Be sure to connect the positive cable (+) first and then the
q
negative or earth cable (-) when connecting the booster ca-
bles. After the start, disconnect first the negative or earth (ñ)
cable and then the positive cable (+).
Connect the batteries in parallel: positive to positive and ne-
q
gative to negative.
When connecting the earth cable to the frame of the machi-
q
ne to be started, operate as far as possible from the battery.
