Wayne-Dalton 3790 Lock Arm Installation, Turn increments, Confirm adjustment, 15308mm 8000 Series

Adjusting Detent

(Continued)

a. If the motor does not pivot down, or only pivots down partially, the detent pin is set too hard.

Using a flat tip screwdriver, turn the detent pin counterclockwise in 1/8

turn increments.

Operate the door to confirm adjustment.

Repeat procedure until motor pivots to full down position when the door is completely closed.

b. If the motor pivots down prematurely (before the door is completely closed) or if the motor is “slapping” too aggressively against the top of the door, the detent pin is set too soft.

Using a flat tip screwdriver, turn the detent pin clockwise in 1/8 turn increments. Operate the door to

confirm adjustment.

Repeat procedure until motor pivots to full down position when the door is completely closed.
