REMARK
If the purified water is added to above UPPER LEVEL line, remove the fluid by using a syringe to lower the level
to UPPER LEVEL line.
Neutralize the removed fluid with baking soda (sodium bicarbonate), then flush it away with a large amount of
water.
If necessary, consult 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 battery box cover (1).
2.
Remove cap (2) at the top of the battery and check the
electrolyte level through electrolyte filler port (3).
3.
If the electrolyte does not reach the sleeve (4), always add
the purified water (e.g. commercially available replenish-
ment water for a battery) so that the level reaches the bot-
tom of the sleeve (UPPER LEVEL line).
(A) Correct level: Electrolyte level is up to bottom of
sleeve, so surface tension causes electrolyte surface to
bulge and pole plate appears to be warped.
(B) Low level: Electrolyte level does not reach the bottom
of sleeve, so pole plate appears straight and not to be
warped.
4.
After adding the purified water, tighten cap (2) securely.
5.
Close the battery box cover (1).
REMARK
If purified water is added to above the bottom tip of the sleeve, use a syringe to remove electrolyte.
Neutralize the removed fluid with baking soda (sodium bicarbonate), then flush it away with a large amount of
water.
If necessary, consult your Komatsu distributor or your battery manufacturer.
METHOD FOR CHECKING ELECTROLYTE LEVEL ON INDICATOR ETC
If it is possible to use an indicator to check the electrolyte level, follow the instructions given.
