Precautions for Protective
Devices
Precautions for Battery
Do not remove any circuits of the
protection device.
* Otherwise, the protective device may not work
in the event of an abnormality, which may cause
personal injury or damage to the devices.
If a protection device activates,
inspect the cause of the abnormality.
* If the cause cannot be determined, contact your
MHIET dealer.
Do not use the battery when the
battery fluid level is below the
"LOWER LEVEL" mark.
* Otherwise, degradation of the inner metal parts
or lowering of the battery fluid level will be
accelerated, which may cause an explosion or
a fire.
* Replace the battery with a new one.
Do not short the battery terminals
with a tool or other metal objects.
* A short circuit may cause explosion, fire,
electric shock or fusing of the terminals.
When working with the battery, obey
the manufacturer's operation manual
or SDS.
* If you accidentally swallow battery fluid, rinse
your mouth with plenty of water and then drink
lots of water, and seek immediate medical
attention.
Remove water or debris on the top of
the battery.
* Otherwise, a short circuit may occur and result
in a fire.
When disconnecting battery
terminals, always remove the
negative (-) terminal first. When
connecting the battery, always
connect the positive (+) terminal first.
* Otherwise, a short circuit may cause an electric
shock or fusing of the terminals.
Charge the battery in a well-
ventilated area.
* Charging the battery in a poor ventilated area
could let hydrogen gas accumulate, which could
cause a fire.
