Turn the key switch and the vacuum switch ON (I). When the actuator stops, the plastic nut should be
located at the 9-1/4 inch (23.8 cm) position.
If the position of the plastic nut is between 9-1/8 and 9-3/8 inches (23.4 and 24 cm), no adjustment is
required.
•
If the position of the plastic nut is less than 9-1/8 inches (23.4 cm), remove the adjuster cover and slowly
turn the adjuster clockwise. The actuator should run briefly each time that the adjuster is turned. When
the plastic nut is at the 9-1/4 inch (23.8 cm) position, the adjustment is complete.
•
If the position of the plastic nut is more than 9-3/8 inches (24 cm), remove the adjuster cover and slowly
turn the adjuster counter-clockwise. Then turn the vacuum switch off, wait for the actuator to stop, turn
the vacuum switch back on, wait for the actuator to stop and check the position of the plastic nut again.
Repeat this procedure until the plastic nut stops at the 9-1/4 inch (23.8 cm) position.
Note: Each click of the adjuster will change the travel of the plastic nut by about 1/16 inch (1.5 mm).
