Engine speed

See blueprints: wc_gr001300

Generators require a non-adjustable engine speed in order to maintain the 
correct voltage. The engine speed is controlled by a governor that automatically 
adjusts to the changing loads of the engine in order to maintain a constant RPM. 
There is no gas regulator.

To set the correct engine speed:

Unscrew the RPM adjusting screw 

(a)

 in and out until a zero load RPM of 3100 

RPM is reached.

NOTE:

 Tools and other electrical equipment can be damaged if the engine 

speed is set too high or too low.

Use the technical data to set engine speed without load or idle.

1. Start the engine and allow it to warm up to the normal operating temperature.

2. Screw in the choke coil stop screw 

(a)

 to increase the speed. Unscrew the 

choke coil stop screw to reduce the speed. Ensure that the throttle lever is 
touching the choke coil stop screw before measuring the RPM.
