WARNING
Do not use the battery if the battery electrolyte level is below LOWER LEVEL line. If you do so, it will
deteriorate the battery inside and reduce the service life of the battery. In addition, it may cause an ex-
plosion.
Do not bring any open flame near the battery. Otherwise, it may explode since the battery generates the
flammable gas.
Battery electrolyte is dangerous object. If it gets in your eyes or on your skin, wash it off with a large
amount of water and consult a doctor.
Do not use a dry wipe to clean the battery. A wet wipe will prevent fire or explosion from static electrici-
ty.
NOTICE
Do not add the electrolyte to the battery exceeding UPPER LEVEL line. If the electrolyte level is too
high, it may leak and cause damage to the paint surface or corrode other parts.
If the battery water may freeze after refilling with the purified water (such as a commercial battery fluid),
do the replenishment before the day's work on the next day.
