START ThE ENgINE
The speed control unit governed speed setting is factory set at approximately engine idle speed. (1000 Hz., speed sensor signal or 600 RPM)
If the engine does not start, adjustment of the speed potentiometer may be required.
Crank the engine with DC power applied to the governor system. The actuator will energize to the maximum fuel position until the engine
starts. The governor system should control the engine at a low idle speed. If the engine is unstable after starting, refer to Section 8 ADJUST-
ING FOR STABILITY.
