Follow instructions which apply to your door type as
illustrated below and on the following page.
SECTIONAL
DOORS ONLY
• 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.
• Figure 1:
- Fasten straight door arm section to outer trolley with
the 5/16"x1" clevis pin. Secure the connection with a
ring fastener.
- Fasten curved section to the door bracket in the
same way, using the 5/16"xl-1/4"
clevis pin.
IMPORTANT:
The groove on the straight door arm
MUST face away from the curved door arm (Figure 4),
• 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, Hole alignment
alternative:
- if holes in curved arm are above holes in straight
arm, disconnect straight arm. Cut about 6" (15 cm)
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
bolts, lock washers and nuts.
• Pull the emergency release handle toward the opener
at a 45 ° angle so that the trolley release arm is
horizontal. Proceed to Adjustment Step 1, page 27.
Trolley will re-engage automatically when opener is
operated.
