1.
Remove the cap (2) at the top of the battery and check the
electrolyte level through electrolyte filler port (3).
2.
If the electrolyte does not reach the sleeve (4), always add
the purified water (such as a commercial battery fluid) so
that the level reaches the bottom 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.
3.
After adding the purified water, tighten the cap (2) securely.
REMARK
If the purified water is added to above the bottom tip of the sleeve, use a syringe to remove the electrolyte. Neu-
tralize the removed electrolyte 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.
