Connect Door Arm to Trolley
Follow instructions which apply to your door
type as illustrated.
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 door) about 2" as shown in
Figures 1, 2 and 3.
Figure 2:
• 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 3:
• If holes in curved arm are above holes in straight
arm, disconnect straight arm. Cut about 6" from
the solid end. Reconnect to trolley with
cut end
down as shown.
• Bring arm sections together.
• Find two pairs of holes that line up and join with
screws, lock washers and nuts.
Proceed to Adjustment Step 1, page 28. Trolley will re-engage automatically when the opener is operated.
