Follow instructions which apply to your door type
as illustrated below and on page 27.
Make sure garage door is fully closed. Pull the manual release handle to disconnect the outer trolley from the inner
trolley. Slide the outer trolley back (away from the door) about 2" as shown in Figures 1, 2 and 3.

that line up and join sections. Select holes as far apart
as possible to increase door arm rigidity.
