Method For Checking And Adjusting Air Conditioner Compressor Belt Tension; Outriggers And Blade Pins Lubrication Method - Komatsu PW118MR-11 Operation & Maintenance Manual

MAINTENANCE PROCEDURE
REMARK
If the purified water is added to above UPPER LEVEL (U.L.) line, remove the fluid by using a syringe to lower
the level to UPPER LEVEL (U.L.) line. Neutralize the removed electrolyte with baking soda (sodium bicarbon-
ate), then flush it away with a large amount of water. If necessary, consult your Komatsu distributor or a battery
manufacturer.
If it is impossible to check electrolyte level from side of battery
If it is impossible to check the electrolyte level from the side of the battery, or there is no UPPER LEVEL line on
the side of the battery, check according to the following procedures.
1.
Remove the cap (1) from the top of the battery.
2.
Look into fluid filler port (2) and check the electrolyte level.
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) 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.
4.
After adding the purified water, tighten the cap (1) securely.
REMARK
If purified water is added to above the bottom tip of the sleeve, use a syringe to remove 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.

OUTRIGGERS AND BLADE PINS LUBRICATION METHOD

NOTICE
If any unusual noise is generated from any greasing point, perform the greasing regardless of the
greasing interval.
Perform the greasing every 10 hours for the first 50 hours of operation on a new machine.
After the machine is subjected to digging work in the water, be sure to grease the wet pins.
Prepare a grease pump.
