Automatic Engine Adjustment
To give accurate control, store the required RPM setting on the controller by carrying out the automatic engine adjustment
procedure.
This will be necessary after fitting a new controller or throttle motor or after adjusting/replacing the control link between the
engine and throttle motor.
Note: If a new throttle motor is fitted or cable/linkage adjusted, the controller must have the memory wiped before
programming can commence.
