12. OPERATION 12.3 OPERATIONS AND CHECKS AFTER STARTING ENGINE After starting the engine, do not immediately start operations. First, carry out the following operations and checks. NOTICE Avoid abrupt acceleration until the warming-up run is com- pleted. Do not run the engine at low idling or high idling for more than 20 minutes. If it is necessary to run the engine at low idling or high idling, apply a load or run at a medium speed from time to time. 1. After the warming-up operation, check that the machine monitor is normal. If there is any abnormality, carry out maintenance or repair.
Run the engine under a light load until the engine water temperature gauge and air pressure gauge enter the green range. When the AISS switch is at the AUTO position and the engine water temperature is still low, high idling revolution is automatically maintained (for electronic governor specification). 2. Check that there is no abnormal exhaust gas color, noise, or vibration. If any abnormality is found, repair it. 2-67
