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 fuel to slobber through the exhaust system. Loss of power and/or poor performance may result.To maintain engine efficiency and performance, apply a full load to the engine on an hourly basis. The engine can also be operated at a load level that is greater than 30 percent. These conditions will burn excess carbon from the cylinders.Operating in transmission warm-up mode will raise exhaust temperatures and help reduce slobber.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
Operation of the jacket water heater is recommended if the engine is operating at a low load in extreme cold.
