E. Discharge the air in the walking motor (when the oil in the casing of the walking
motor is discharged)
1) Run the engine at idle speed and loosen
the exhaust plug. If oil comes out, tighten
the screw plug.
2) Run the engine at idling speed and
rotate the working device 90 degrees so
that it is located on the side of the crawler.
(As shown on the right)
3) Jack up the machine with the working
device, keep the crawler on one side
slightly away from the ground, and rotate
the crawler for 2 minutes under no load.
Repeat this action on the left and right
tracks and rotate the tracks forward and
backward equally.
F. Exhaust the air in the accessories
If the accessory is installed, run the engine at idle speed and operate the accessory pedal
several times (about 10 times) until the air is discharged from the accessory oil circuit.
Note:
1. If the manufacturer specifies a specific exhaust method, which shall be followed
strictly.
2. After the exhaust operation is completed, turn off the engine and let the machine
stand for at least 5 minutes before starting operation to eliminate air bubbles in the
oil in the hydraulic cylinder.
3. There shall be no leakage during the inspection. Wipe the spilled oil if any.
4. After the exhaust operation is completed, check the oil level, and fill if the oil level
is low.
