MAINTENANCE
3.
Remove caps (2) from the top of the battery.
4.
Look into fluid filler port (3) and check the electrolyte level.
5.
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) Suitable level
Electrolyte level is up to bottom of sleeve, so surface ten-
sion causes electrolyte surface to bulge and poles appear
bent.
(B) Low level
Electrolyte level is not up to bottom of sleeve, so poles appear straight and not bent.
6.
After adding the purified water, tighten cap (2) securely.
7.
Return rubber cover (1) to its original position.
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 nec-
essary, consult your Komatsu distributor or your battery manufacturer.
