MAINTENANCE
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.
q 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.
Open cover (1) at the rear left side of the machine. The batter-
ies are installed at (A) part.
When Checking Electrolyte Level from Side of Battery
If it is possible to check the electrolyte level from the side of the battery, check as follows.
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.
2. If the electrolyte level is below the midway point between
the UPPER LEVEL (U.L.) and LOWER LEVEL (L.L.) lines,
remove cap (2) and add distilled water to the U.L. line.
3. After adding distilled water, tighten cap (2) securely.
REMARK
If distilled water is added to above the UPPER LEVEL (U.L.)
line, use a syringe to lower the level to the UPPER LEVEL
(U.L.) line. Neutralize the removed fluid with baking soda
(sodium bicarbonate), then flush it away with a large amount of
water or consult your Komatsu distributor or battery maker.
When it is Impossible to Check Electrolyte Level from Side of Battery
If it is impossible to check the electrolyte level from the side of the battery, or there is no display of the UPPER
LEVEL line on the side of the battery, check as follows.
