WARNING
q
It is dangerous to charge a battery when installed on a
machine. Make sure that it is removed before charging.
q
When checking or handling the battery, stop the engine
and turn the starting switch and battery disconnect
switch keys to the OFF positions.
q
The battery generates hydrogen gas, so there is a haz-
ard of explosion. Do not bring lighted cigarettes near
the battery, or do anything that will cause sparks.
q
Battery electrolyte is dilute sulphuric acid, and it will
attack your clothes and skin. If it gets on your clothes
or on your skin, immediately wash it off with a large
amount of water.
If it gets into your eyes, wash them immediately with
fresh water, then consult a doctor for treatment.
q
When handling batteries, always wear protective eye
glasses and rubber gloves.
q
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,
there is a danger that it will cause a spark, so be
extremely careful.
q
If the terminals are loose, there is a danger that the
defective contact may generate sparks that will cause
an explosion.
Install the cable terminals securely.
q
When removing or installing the cable terminals, check
which is the positive (+) terminal and which is the nega-
tive (-) terminal.
