If the oil pressure does not rise within ten seconds after starting, stop the engine and make necessary repairs.
Warm-up
1. Run the engine at low idle for three to five minutes, or until the jacket water temperature starts to rise.2. Check all gauges during the warm up period. The warm up requires approximately:* five minutes when the temperature is over 0°C (32°F).* fifteen minutes when the temperature is below 0°C (32°F).More time may be necessary when the temperature is below -18°C (0°F).3. Make another walk-around inspection. Check the engine for fluid and air leaks. Measure the crankcase oil level on the LOW IDLE side of the dipstick. Maintain the oil level between the ADD and FULL marks.4. Increase the rpm to 1/2 rated speed. Check for fluid and air leaks. The engine may be operated at full rated speed and full load when the jacket water temperature reaches 66°C (150°F).Applying the Load
To apply the load:1. Make sure the engine gauges register in normal ranges with the engine operating at rated speed. If the driven equipment is already engaged without load, make sure any equipment gauges register in normal ranges.2. Always increase engine speed to rated speed before applying the load. Close the generator or main circuit breaker without a load on the equipment (if possible).3. Apply the load. Begin operating the engine at low load. Check the gauges and equipment for proper operation. After normal oil pressure is reached and the temperature gauge begins to move, the engine may be operated at full load.If the load varies, or is cyclic, the governor will adjust the engine speed as required.Extended operation at low idle or reduced load may cause increased oil consumption and carbon build-up in the cylinders. This carbon build-up results in loss of power and/or poor performance. When operating at reduced load, the engine should be fully loaded to burn excess carbon from the cylinders at least every four hours. Check the gauges and equipment frequently while operating under load.Engine Operation
Proper operation and maintenance are key factors in obtaining the maximum life and economy of the engine. Following the directions in this manual will lower operating costs.The time needed for the engine to reach the normal mode of operation is usually less than the time taken for a walk-around-inspection of the engine.After the engine is started and the warm up is completed, the engine can be operated at rated speed and low power. The engine will reach normal operating temperature faster when operated at rated speed and low power demand than when idled at no load. Typically the engine should be up to operating temperature in a few minutes.Gauges readings should be observed and the data recorded frequently while the engine is operating. Comparing the data over time will help determine normal readings for each gauge, and help detect abnormal operating developments. Significant changes in the readings should be investigated.Fuel Conservation Practices
