If the work equipment goes down under its own weight and
contacts the ground, the accumulator is normal.
If the work equipment does not go down or stops in midway,
the charged pressure of the gas in the accumulator for the hy-
draulic circuit has probably dropped. Ask your Komatsu distrib-
utor for inspection.
This completes the inspection. After completion of the inspection, set the lock lever to LOCK position and turn
the starting switch to OFF position.
METHOD FOR RELEASING PRESSURE IN HYDRAULIC CIRCUIT
1.
Lower the work equipment to the ground.
Keep the crusher attachment jaws, etc. closed.
2.
Operate the operating portion (g) of the lock lever to set it
securely to LOCK position (L).
If an attachment is installed, set the lock pin of the attach-
ment control pedal to position (c) where you can operate
the pedal.
3.
Perform the following procedure within 15 seconds.
After the engine stops, the accumulator pressure decreas-
es gradually. You can check only just after the engine
stops.
1) Turn the starting switch to OFF position (A), and then
stop the engine.
