(1) All moving parts must be subjected to no-load motion (forward rotation and reverse rotation) before the test run, and the operation of each part must be checked.
(2) Start the main motor for leveling the main engine with no-load test run. Run continuously for 1~2 hours in both positive and negative directions. Check the connection and operation of various components and check the leveling brake effect of the main engine brake.
(3) It is considered that the load test run can be carried out after the air run is good, and also check the various parts of the machine. If any abnormality is found, it should be immediately stopped, checked or adjusted to eliminate the abnormal phenomena, and then retry the operation. The machine operation should be smooth and smooth. Significant vibration and noise.
(4) After passing the trial operation, it can be put into production. After the production has been completed, the load of the machine must not exceed 80% of the rated load before the various parts of the machine have been fully run-in.
