Engine Speed Adjustments
Adjustments to the engine speed settings are not nor-
mally necessary unless the throttle linkage, injection
pump, or governor mechanism have been repaired,
rebuilt, replaced or are not operating correctly.
If your machine is not equipped with the optional ta-
cho
meter, use a vibration-type tachometer to set engine
speed.
Engine must be running to do these adjust-
ments. To guard against possible personal
injury, engage parking brake and keep hands,
feet, face and other parts of body away from
fan or other moving parts.
