A—Throttle Handle

To increase engine speed, turn throttle handle (A), if
equipped, to the horizontal position and pull out until
desired engine speed is obtained. Turn the handle in
either direction to lock throttle position. The handle is
pushed inward to decrease engine speed.

NOTE: On engines without handle, use throttle lever to

control engine speed.

Avoid Excessive Engine Idling

Prolonged idling may cause the engine coolant
temperature to fall below its normal range. This, in
turn, causes crankcase oil dilution, due to incomplete
fuel combustion, and permits formation of gummy
deposits on valves, pistons, and piston rings. It also
promotes rapid accumulation of engine sludge and
unburned fuel in the exhaust system.

Once an engine is warmed to normal operating
temperatures, engine should be idled at slow idle

speed. Slow idle speed for this engine is 850 rpm at
factory. If an engine will be idling for more than 5
minutes, stop and restart later.

NOTE: Generator set applications where the governor

is locked at a specified speed may not have a
slow idle function. These engines will idle at no
load governed speed (high idle).
