MAINTENANCE
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.
METHOD FOR CHECKING ELECTROLYTE LEVEL WHEN IT IS IMPOSSIBLE TO
CHECK FROM SIDE OF BATTERY
If it is impossible to check the electrolyte level from the side of the battery, or there is no UPPER LEVEL line on
the side of the battery, check as follows.
1.
Open the hydraulic tank inspection cover on the left side of the machine.
2.
Remove the plastic sheet (1) installed above the battery.
