SERVICE PROCEDURE
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. Use a wet cloth to clean the area around the electrolyte level
lines and check that the electrolyte level is between UPPER
LEVEL (U.L.) and LOWER LEVEL (L.L.) lines.
2. If the electrolyte level is below the midway point between
UPPER LEVEL (U.L.) and LOWER LEVEL (L.L.) lines, remove
cap (2) and add purified water (e.g. commercially available
replenishment water for a battery) to U.L. line.
3. After adding distilled water, tighten cap (2) securely.
REMARK
If distilled 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 or consult your Komatsu distributor or battery maker.
