TROUBLESHOOTING

IF BATTERY IS DISCHARGED

When checking or handling the battery, stop the
engine and turn the starting switch key to the OFF
position.
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.
Battery electrolyte is dilute sulphuric acid, and it will
attack your clothes and skin. If it gets on your clothes
or on your skin, wash it immediately off with large
amounts of water. If it gets in your eyes, wash it out
with fresh water, and consult a doctor.
When handling batteries, always wear protective gog-
gles and rubber gloves.
When removing the battery, first disconnect the cable
from the ground (normally the negative (-) terminal).
When installing, install the positive (+) terminal first.
If a tool touches the positive terminal and the chassis,
there is danger that it will cause a spark, so be
extremely careful.
If the terminals are loose, there is danger that the
defective contact may generate sparks that will cause
an explosion.
When removing or installing the terminals, check
which is the positive (+) terminal and which is the neg-
ative (-) terminal.
Green rust around the terminals is a cause of self-dis-
charge of the battery. Polish the terminals with sand-
paper. After removing the rust, coat the terminals
thinly with grease before installing.
