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 (1) from the top surface of the battery, look
into the filler port (3), and check the electrolyte level. If the
electrolyte level does not reach the sleeve (2), add distilled
water immediately to the bottom of the sleeve (max. elec-
trolyte level: UPPER LEVEL).
q
(A) Suitable level: Electrolyte level is up to bottom of sleeve
(2), so surface tension causes electrolyte surface to bulge
and poles appear bent.
q
(B) Low: Electrolyte level is not up to bottom of sleeve (2),
so poles appear straight and not bent.
2.
After adding distilled water, tighten cap (1) 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.
