METHOD FOR CHECKING ELECTROLYTE LEVEL FROM SIDE OF BATTERY
If the battery is wiped with a dry cloth, static electricity may cause a fire or explosion.
If it is possible to check the electrolyte level from the side of the battery, check as follows.
1.
Open the hydraulic tank inspection cover on the left side of the machine.
2.
Clean around the electrolyte level line with a cloth wet with water.
3.
Check the electrolyte level.
• When the electrolyte level is between UPPER LEVEL
(U.L.) line and LOWER LEVEL (L.L.) line.
The battery electrolyte level is proper.
• When the electrolyte level is below the center line be-
tween UPPER LEVEL (U.L.) line and LOWER LEVEL
(L.L.) line.
The battery electrolyte level is low. Add purified water
according to the following procedure.
1)
Remove the plastic sheet (1) installed above the bat-
tery.
2)
Remove cap (2) immediately and add purified water
(example: commercially available battery liquid) up to
UPPER LEVEL (U.L.) line.
3)
After adding the purified water, tighten cap (2) secure-
ly.
REMARK
If purified water is added to above U.L. line, use a syringe to lower the level to U.L. line. Neutralize the removed
fluid with baking soda (sodium bicarbonate), then flush it away with a large amount of water. If necessary, con-
sult your Komatsu distributor or a battery manufacturer.
