Method For Checking Brake Performance - Komatsu D85EX-18 Operation & Maintenance Manual

MAINTENANCE PROCEDURE
3.
Remove caps (2) from the top of the battery.
4.
Look into fluid filler port (3) and check the electrolyte level.
(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: Electrolyte level is not up to bottom of sleeve, so
poles appear straight and not bent.
If the electrolyte does not reach sleeve (4), always add the
purified water (such as a commercial battery fluid) so that
the level reaches the bottom of sleeve (4) (UPPER LEV-
EL).
5.
After checking adding the purified water, tighten caps (2)
securely.
REMARK
If the purified water is added to above the bottom of sleeve (4), use a syringe to remove electrolyte to the bot-
tom of sleeve (4). 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.
METHOD FOR CHECKING ELECTROLYTE LEVEL ON INDICATOR ETC
If it is possible to use an indicator to check the electrolyte level, follow the instructions given.
