MAINTENANCE
SERVICE PROCEDURE
CHECK LEVEL OF BATTERY ELECTROLYTE
Carry out this procedure before operating the machine.
WARNING
Do not use the battery if the battery electrolyte level is below the LOWER LEVEL line. This will accelerate deterioration of the
inside of the battery and reduce the service life of the battery. In addition, it may cause an explosion.
The battery generates flammable gas and there is danger of explosion, do not bring fire or sparks near the battery.
Battery electrolyte is dangerous. If it gets in your eyes or on your skin, wash it off with a large amount of water and consult a
doctor.
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.
NOTICE
If there is a fear that the battery water may freeze after refilling with purified water (e.g. commercially available replenishment water
for a battery), do the replenishment before the day's work on the next day.
Inspect the battery electrolyte level at least once a month and follow the basic safety procedures given below.
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.
Remove hook (1), then open inspection cover (2).
2.
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.
3.
If the battery electrolyte level is below the mid point between
the UPPER LEVEL and LOWER LEVEL, immediately remove
cap (3) and add distilled water (or commercially available
battery filler solution) to the UPPER LEVEL.
4. After adding distilled water, tighten cap (3) securely.
REMARK
If distilled water is added to above the U.L. line, use a syringe to
lower the level to the 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.
