IF THERE ARE ANY DISCREPANCIES, NECESSARY MEASURES SHOULD BE TAKEN.AFTER STARTING THE DIESEL ENGINE, THE SPEED SHOULD BE GRADUALLY INCREASED. AFTER CHECKING AND CONFIRMING THAT EVERYTHING IS IN GOOD CONDITION, IT CAN BE OPERATED AT LOW SPEED TO RATED SPEED WITHOUT LOAD. WHEN RUNNING WITHOUT LOAD, PAY ATTENTION TO CHECKING THE OIL PRESSURE FOR ANY ABNORMAL NOISE, EXCITATION CURRENT, THREE-PHASE VOLTAGE CHANGES, ETC. IF THERE ARE ANY ABNORMAL SITUATIONS, STOP THE MACHINE IMMEDIATELY FOR INSPECTION. AFTER INVESTIGATING THE SITUATION, RESTART. IF EVERYTHING IS NORMAL, IT CAN BE PUT INTO NORMAL OPERATION.
