2.
If the electrolyte does not reach the sleeve (6), 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 (4) securely.
REMARK
If purified water is added to above the bottom tip of the sleeve, use a syringe to remove the electrolyte.
Neutralize 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 your battery manufacturer.

frame and axle, the bolts will break. Tighten any loose bolts im-
mediately.
