Place-the run-off toggle switch in the "RUN" position and the idle normal toggle switch in the "IDLE"

position.

Press in on the permissive start button to activate the solenoid to the "HIGH IDLE" position.

Hold in requires .5 amperes.

Loosen the locknut and adjust the linkage to obtain full stop-to-stop travel (para. 3-12).
