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.
1. Remove hook (1), then open inspection cover (2).
2.
Remove cap (3) at the top of the battery and look through the
filler port to check the electrolyte level. If the electrolyte is not
up to the sleeve, immediately add distilled water (or
commercially available battery filler solution) to the bottom of
the sleeve (UPPER LEVEL).
Use the diagram below for reference, and check if the electrolyte reaches the bottom of the sleeve.
3.
After adding distilled water, tighten cap (3) securely.
REMARK
If water is added to above the bottom tip of the sleeve, use a pipette to remove electrolyte. Neutralize the removed
electrolyte with sodium bicarbonate, then flush it away with a large amount of water. If necessary, contact your
Komatsu distributor or your battery maker.
WHEN IT IS POSSIBLE TO USE INDICATOR TO CHECK ELECTROLYTE LEVEL
If it is possible to use an indicator to check the electrolyte level, follow the instructions given.
