BATTERY CHARGES
When charging the battery, there is danger that the battery may
explode if it is mishandled. Follow the instructions in ""WARMING
UP OPERATION (161)" and the instruction manual supplied with
the charger, and be sure to observe the following precautions.
●
Set the voltage of the charger to match the voltage of the bat-
tery to be charged. If the voltage is not selected correctly, the
charger may overheat and cause an explosion.
●
Connect the positive (+) charger clip of the charger to the
positive (+) terminal of the battery, then connect the negative
(-) charger clip of the charger to the negative (-) terminal of
the battery. Be sure to connect the clips securely.
●
Set the charging current to 1/10 of the value of the rated bat-
tery capacity; when doing rapid charging, set it to less than
the rated battery capacity.
If the charger current is too high, the electrolyte will leak or
dry up, and this may cause the battery to catch fire and
explode.
●
If the battery electrolyte is frozen, do not charge the battery or
start the engine with a different power source.
There is a danger that this will ignite the battery electrolyte
and cause the battery to explode.
●
Do not use or charge the battery if the battery electrolyte level
is below the LOWER LEVEL line. This may cause an explo-
sion. Always check the battery electrolyte level periodically
and add distilled water to bring the electrolyte level to the
UPPER LEVEL
