PRECAUTIONS FOR CHARGING BATTERY
k k
WARNING
When charging the battery, if the battery is not handled
correctly, there is a danger that the battery may explode.
Always follow the instructions in the precautions for dis-
charged battery and the instruction manual accompanying
the charger, and observe the following.
• Set the voltage of the charger to match the voltage of
the battery to be charged. If the correct voltage is not
selected, the battery charger may overheat and cause
an explosion.
• Connect the positive (+) charger clip of the battery
charger to the positive (+) terminal of the battery, then
connect the negative (-) charger clip of the battery
charger to the negative (-) terminal of the battery. Be
sure to attach the clips securely.
• Set the charging current to 1/10 or less of the value of
the rated battery capacity. When performing rapid
charging, set it to less than the rated battery capacity.
If the charger current is too high, the electrolyte will
leak or the battery cells will dry up, and this may cause
the battery to catch fire and explode.
• Do not charge the battery or start the engine with a dif-
ferent power source if the battery electrolyte is frozen.
This may ignite the battery electrolyte, and battery
may explode.
• Do not use or charge the battery if the battery electro-
lyte level is below LOWER LEVEL line. This may cause
an explosion. Check the battery electrolyte level peri-
odically and add the purified water (such as a commer-
cial battery fluid) to bring the electrolyte level to UP-
PER LEVEL line.
