Engine Operating GuidelinesChanging Engine Speed-Standard(Mechanical) GovernorNOTE: Throttle levers are usually supplied by OEMmanufacturer. Consult supplier literature tofamiliarize yourself with throttle lever used on yourengine.To increase engine speed, turn throttle handle (A) to thehorizontal position and pull out until desired engine speedis obtained. Turn the handle in either direction to lockthrottle position. The handle is pushed inward to decreaseengine speed.A—Throttle HandleThrottle Handle on North American Instrument PanelRG11534 –UN–01DEC00RG,RG34710,5052–19–30JAN98–1/1Idling EngineAvoid excessive engine idling. Prolonged idling maycause the engine coolant temperature to fall below itsnormal range. This, in turn, causes crankcase oildilution, due to incomplete fuel combustion, andpermits formation of gummy deposits on valves,pistons, and piston rings. It also promotes rapidaccumulation of engine sludge and unburned fuel inthe exhaust system.Once an engine is warmed to normal operatingtemperatures, engine should be idled at slow idlespeed. Slow idle speed for this engine is 850 rpm atfactory. If an engine will be idling for more than 5minutes, stop and restart later, or set engine speed at1200 rpm.NOTE: Generator set applications where the governoris locked at a specified speed may not have aslow idle function. These engines will idle at noload governed speed (high idle).RG,RG34710,5053–19–11FEB03–1/115-18 060106PN=58
