Using the actuator knob, turn the shaft counterclockwise to the extreme left. If the shaft is not turned to this extreme position where the white line on the knob points to the number 1 position shown on the side of the switch, proper setting cannot be achieved. 2. Remove the knob from the shaft and loosen the nut far enough to allow raising the stopper plate for resetting to the desired position. 3. Note the position numbers on the side of the switch; these correspond to the terminal numbers and stopper holes. Insert the stopper in the hole numbered for the maximum desired number of stop settings. Satisfactory switch functioning cannot be assured if the stopper plate is not properly positioned. 4. Tighten the nub (beveled side up) firmly against the stopper plate.
