(1) Oil pump exhaust
① Release the exhaust plug and confirm if there is any oil leakage
② If there is oil leakage, tighten the exhaust plug. The tightening torque is 19.5=2.45N-
③ If the exhaust blockage does not leak oil, then: ① In the case of loose exhaust blockage F, remove the hose and elbow ② Install the elbow
Add oil to the hole until oil seeps out from the exhaust blockage; ③ Install the elbow and hose, tighten the exhaust plug ④, and after completing the above tasks,
When starting the engine, make it idle at low speed; m,
(2) Oil cylinder exhaust
① Start the engine and idle at low speed for 5 minutes,
② The engine runs at low speed, and the boom moves down and down repeatedly 4 to 5 times (about loo - before the piston rod reaches its maximum stroke, be careful not to
Don't let it flow excessively
③ The engine idles at high speed, the boom moves up and down repeatedly 4-5 times, and then the engine runs at low speed until the piston rod reaches its maximum movement
Cheng Make the overflow valve overflow.
④ The boom and bucket are also carried out in the order of steps (2) and (3)
(3) Rotary motor exhaust
① Engine running at low speed: loosen exhaust blockage, confirm if there is oil leakage
② If there is no oil leakage due to exhaust blockage, turn off the engine and inject oil into the motor housing through the blockage port; Tighten the exhaust blockage,
The tightening torque is 166.9+19.6N m
