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.

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.
