ate deterioration of the inside of the battery and reduce the service life of the battery. In addition, it
may cause an explosion.

of water and consult a doctor.
NOTICE
q
When adding distilled water to the battery, do not allow the battery electrolyte to go above the UPPER
LEVEL line. If the electrolyte
level is too high, it may leak and cause damage to the paint surface or corrode other parts.

When adding distilled water in cold weather, add it before starting operations in the morning to pre-
vent the electrolyte from freezing.
Inspect the battery electrolyte level at least once a month and follow the basic safety procedures given below.

1. Use a wet cloth to clean the area around the electrolyte
level lines and check that the electrolyte level is between
the UPPER LEVEL (U.L.) and LOWER LEVEL (L.L.) lines.
If the battery is wiped with a dry cloth, static electricity may
cause a fire or explosion.
