2.
Remove cap (1) at the top of the battery and check the
electrolyte level through electrolyte filler port (2).
3.
If the electrolyte does not reach the sleeve (3), 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 bot-
tom of sleeve, so pole plate appears straight and not
to be warped.
4.
When you add the purified water to the cell of cap (1), add
it to other cells as well.
5.
After adding the purified water, tighten cap (1) securely.
REMARK
If the purified water is added to above the bottom 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 a battery manufacturer.
