PRECAUTIONS FOR CHARGING BATTERY 3
When charging the battery, if the battery is not handled cor-
rectly, there is danger that the battery may explode. Always
follow the instructions in “BATTERY (3-141)“ and the instruc-
tion manual accompanying the charger, and do as follows.
q
Do not use or charge the battery if the level of the battery
electrolyte is below the lower level. This may cause an
explosion. Always inspect the battery electrolyte level peri-
odically and add distilled water to the upper level.
q
Set the voltage of the charger to match the voltage of the
battery to be charged. If the correct voltage is not selected,
the charger may overheat and cause an explosion.
q
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 attach the clips
securely.
q
Set the charging current to 1/10 of the value of the rated battery capacity; when carrying out 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.
q
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.
