1.
Remove the cap (2) at the top of the battery and check the
electrolyte level through electrolyte filler port (3).
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 bot-
tom of sleeve, so pole plate appears straight and not
to be warped.
2.
After adding it, tighten the cap (2) securely.
REMARK
If it is added to above the bottom tip of the sleeve, use a syringe to remove it. Neutralize the removed fluid
with baking soda (sodium bicarbonate), then flush it away with a large amount of water. If necessary, con-
sult your Komatsu distributor or a battery manufacturer.
