iNSTALLATiON STEP 12
Connect Door Arm to Trolley
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"xl" 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.
