e. Electric Governor System Adjustment
The magnetic pickup and control box have critical adjustments which can affect engine
performance and generator output. Actuator-to-fuel control lever adjustment can also affect engine
performance.
WARNING
When the complete system is to be checked, and /or adjusted, a definite sequence of procedures
should be followed:
First - Check or adjust actuator linkage.
Second - Check or adjust magnetic pickup.
Third - Check or adjust electric control box

(1) Actuator linkage adjustment

The proper adjustment of the mechanical linkage between the electric actuator and engine
speed control lever is important to the satisfactory operation of the complete system.
Exact adjustment instructions such as effective length of rod assembly (6, Fig. 7) , or which hole
in actuator lever to attach ball joint (4) cannot be determined because of slight variations in
brackets, mountings, and engine performance characteristics. However, definite rules must be
followed in making the adjustment:
1. First, adjust linkage to use the FULL TRAVEL of actuator output shaft (2) .
2. Second, make certain that linkage is adjusted such that it can move speed control lever
(8) from FULL IDLE to FULL SPEED position, or VERY CLOSE to FULL SPEED position
to allow engine to pull 125% load.

Engine Specifications
The engine should be equipped with a separate overspeed (overtemperature, or
overpressure) shutdown device, to protect against runaway or damage to the
engine, with possible personal injury or loss of life should the mechanical
governor, or electric control, actuator, fuel controls, driving mechanism, linkage,
or the controller device fails.
