7. Place and lock the lockout cover assembly (B60) on the head of the left side lock screw.
Locked Open Condition
Follow the steps below to change the unit from the unlocked condition to the locked open position.
Refer to Figure 10 for component identification. Before proceeding, ensure the open and closed
position stops are properly adjusted as described in the "Position Stops" section.
1. Operate the actuator to the fully open (counterclockwise) position.
Adjusting the wrong screw does not lock the actuator, and can result in personal injury
or equipment damage. Adjust only the RIGHT-SIDE lock screw to lock the actuator in
the closed position.
2. Loosen the jam nut (B65) on the right side lock screw (B64), as viewed when facing the top of
the heads of the lock screws.
3. Hold the lock screw and turn the jam nut several turns counterclockwise, to the head of the lock
screw.
4. Turn the right side lock screw clockwise several turns until resistance is felt from the lock screw
contacting the notch in the gear (B8).
