MAINTENANCE
SERVICE PROCEDURE
EVERY 250 HOURS SERVICE
Maintenance for every 50 and 100 hours service should be carried out at the same time.
CHECK BATTERY ELECTROLYTE LEVEL
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. Open the cover of the battery box.
There are two battery boxes: One on each side at the rear of the machine.
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 electrolyte level is below the midway point between the
U.L and L.L lines, remove cap (1) and add distilled water to the
U.L line.
4. If distilled water has been added to any cell of cap (1), add
distilled water also to the other cells.
5.
Clean the vents of the battery caps, then close the caps
securely.
Keep the top of the battery clean and wipe it with a wet cloth.
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.
