Assembly

STEP 1 Assemble the rail and trolley

To avoid installation difﬁ culties, do not run the garage door opener until instructed to do so.

The front rail has a cut out “window” at the door end. The front and back rail both have rail tabs.

These rail tabs MUST be on top of the rail when assembled.

1. Remove the straight door arm and hanging bracket packaged inside the front rail and set

aside for Installation Step 5 and 9. NOTE: To prevent INJURY while unpacking the rail

carefully remove the straight door arm stored within the rail section.

2. Align the rail sections on a ﬂ at surface as shown and slide the tapered ends into the larger

ones. Tabs along the side will lock into place.

3. Place the motor unit on packing material to protect the cover, and rest the back end of the rail

on top. For convenience, put a support under the front end of the rail.

4. As a temporary stop, insert a screwdriver into the hole 10” (25 cm) from the front end of the

rail, as shown.

5. Check to be sure there are 4 plastic wear pads inside the inner trolley. If they became loose

during shipping, check all packing material. Snap them back into position as shown.

6. Slide the trolley assembly toward the screwdriver as shown.

7. Slide the rail onto the “U” bracket, until it reaches all the stops on the top and sides of the

“U” bracket.
