Follow instructions which apply to your door type as illustrated below and on the following page.

•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 door) about 200mm as shown in Figures 1, 2 and 3.

Figure 1:

•Fasten straight door arm section to outer trolley with the 8mm x 25mm clevis pin. Secure the connection with a ring fastener.

•Fasten curved section to the door bracket in the same way, using the 8mmx 32mm clevis pin.

Figure 2:

•Bring arm sections together. Find two pairs of holes that line up and join sections. If possible, use the top and bottom holes on the curved door arm, as shown.

Figure 3, Hole Alignment Alternative:

•If holes in curved arm are above holes in straight arm, disconnect straight arm. Cut about 150mm 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 screws, 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 25. Trolley will re-engage automatically when opener is operated.
