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 cap (2) at the top of the battery, look through the water
filler port (3), and check the electrolyte surface. If the
electrolyte does not reach the sleeve (4), add purified water
(e.g. commercially available replenishment water for a battery)
so that the level reaches the bottom of the sleeve (UPPER
LEVEL line) without fail.
(A) Suitable level: Electrolyte level is up to bottom of sleeve,
(B) Low: Electrolyte level is not up to bottom of sleeve, so
poles appear straight and not bent.
2. After adding distilled water, tighten cap (2) 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.
so surface tension causes electrolyte
surface to bulge and poles appear bent.
