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 23. Trolley will

 

re-engage automatically when opener is operated.
