PRECAUTIONS FOR DISCHARGED BATTERY
WARNING
• It is dangerous to charge a battery when installed on a
machine. Make
sure that it is removed before charg-
ing.
• When checking or handling the battery, stop the en-
gine and turn the starting switch and battery discon-
nect switch keys to OFF positions.
• The battery generates hydrogen gas, and it is danger-
ous that it may explode. Do not bring open flame such
as lighted cigarettes near the battery, or do nothing
that will cause sparks.
• Battery electrolyte is dilute sulfuric acid, and it will at-
tack your clothes and skin. If it gets on your clothes or
on your skin, immediately wash it off with a large
amount of clean water.
If it gets in your eyes, wash the eyes immediately with
clean water, then consult a doctor for medical treat-
ment.
• When handling batteries, always wear protective eye-
glasses and rubber gloves.
• When removing the battery, first disconnect the cable
from the ground (normally the negative (-) terminal).
When installing, first connect the cable to the positive
(+) terminal.
If a tool touches the positive terminal and the chassis,
it is dangerous that it may cause a spark. Be extremely
careful.
• If the terminals are loose, it is dangerous that the de-
fective contact may generate sparks, and it may cause
an explosion.
Install the cable terminals securely.
• When removing or installing the cable terminals,
check which is the positive (+) terminal and which is
the negative (-) terminal.
