WARNING
When charging the battery, if the battery is not handled
correctly, there is a hazard that the battery may explode.
Always follow the instructions of "DISCHARGED BAT-
TERY (3-232)" and the instruction manual accompanying
the charger, and do as follows.
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 large, 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.
q
Do not use or charge the battery if the battery electro-
lyte level is below the LOWER LEVEL line. This may
cause an explosion. Check the battery electrolyte level
periodically and add purified water to bring the electro-
lyte level to the UPPER LEVEL line.
