Proper operation and maintenance are key factors in attaining the maximum service life and economy for the engine. Follow the instructions in this Operation and Maintenance Manual in order to minimize operating costs and maximize the service life of the engine.Observe the gauges frequently while the engine is operating. Record the data from the gauges in a log regularly. Compare the data to the specifications for normal engine operation. Comparing the data over time will help to detect changes in engine performance.Investigate any significant change in the gauge readings. Monitor the engine operation and perform adjustments when discrepancies are found.Operating the Engine and the Driven Equipment
Check the gauges and the driven equipment frequently while the engine is operating under a load. The engine can be operated for extended periods of time at full load.Partial Load Operation
Extended operation at reduced load (less than 30%) may cause increased oil consumption and carbon buildup in the cylinders. Extended operation at reduced load may also cause oil to slobber through the exhaust system. This may result in a loss of power and/or poor performance.To maintain engine efficiency and performance, apply a full load to the engine on an hourly basis, or operate the engine at a load level that is greater than 30 percent. A full load or a load greater than 30 percent while operating the engine will burn excess carbon from the cylinders.When possible, before shutting down the engine after running the engine for extended periods at low load, apply a full load for approximately 30 minutes. Running the engine at full load allows excess carbon to burn from the following components: cylinders, pistons and valves. Partial Load Operation In Cold Weather
The use of a jacket water heater is recommended if the engine is operating at a low load in extreme cold.
