with Step 28.
Place the emergency disconnect in the manual
operated position, Motor will pivot to the up
position (see Step 9).
Insert the lock arm into the motor groove and
align with the proper hole depending on your
track radius. To determine the Wayne-Dalton
track radius being used, measure the length of
the flagangle and Torquemaster
®

and compare to the diagram on the right (all
Portland tracks are stamped with radius on the
side of the track).

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.
