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"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"x1-1/4" clevis pin.
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.
