INSTALLATION STEP 9

CONNECT DOOR ARM TO TROLLEY

Follow instructions which apply to your door type as illustrated below and on the
following page.
IMPORTANT: The groove on the straight door arm MUST face away from the curved
door arm (Figure 4).
SECTIONAL DOORS ONLY
1. Make sure garage door is fully closed. Pull the emergency release handle
to disconnect the outer trolley from the inner trolley. Slide the outer trolley
back (away from the pulley) about 8" (20 cm) as shown in Figures 1, 2 and
3.
2. Fasten straight door arm section to outer trolley with the 5/16"x1" clevis
pin. Secure the connection with a ring fastener (Figure 1).
3. Fasten curved section to the door bracket in the same way, using the
5/16"x1-1/4" clevis pin.
4. Bring arm sections together. Find two pairs of holes that line up and join
sections. Select holes as far apart as possible to increase door arm
rigidity (Figure 2).
Hole alignment alternative (Figure 3):
If holes in curved arm are above holes in straight arm, disconnect straight
l
arm. Cut about 6" (15 cm) from the solid end. Reconnect to trolley with cut
end down as shown.
Bring arm sections together.

Pull the emergency release handle toward the opener at a 45° angle so that the
trolley release arm is horizontal. Trolley will re-engage automatically when opener
is operated during the adjustments.
