C)
Vent air from the cylinder
1)
At low engine speed, extend and retract the cylinder to the position that is
about 100mm from the end for 4~5 times. (Be sure not to extend or retract
to the end of the line)
2)
Then, operate each cylinder to the end of its stroke 3~4 times.
3)
Finally, operate each cylinder to the end of its stroke 4~5 times to
completely vent air.
ATTENTION: If you run the engine at high speed or operate the cylinder
to the end of its stroke immediately after starting, the air inside the
cylinder will damage the piston seal and thus damage the cylinder.
D)
Vent air inside the rotary motor (when the oil inside the rotary motor
housing is drained)
ATTENTION: Do not rotate the machine under any circumstances during
the air venting period.
1)
Idle the engine, loosen the air vent screw and check if oil flows out of the
air vent screw.
2)
If no oil comes out, remove the exhaust screw and fill the motor case with
hydraulic oil.
3)
After finishing the exhaust, tighten the exhaust screw.
4)
Finally, run the engine at low idling speed and slowly turn the upper part of
the car body to the left and right respectively at least twice. Until the
exhaust is fully exhausted.
ATTENTION: If the air inside the motor is not exhausted, the bearings of
the slewing motor may be damaged.
E)
Vent air inside the travel motor (when the oil inside the travel motor
housing is exhausted)
1)
Run the engine at idle speed and loosen the air vent screw. If oil flows out,
