Assembly
STEP 1 Assemble the rail and install the trolley
To prevent INJURY from pinching, keep hands and fingers away from the joints while assembling the
rail.
To avoid installation difficulties, 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 rail tab 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 flat 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 restthe backend 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 in the second rail section from the motor
unit,as shown.
5. Checkto be sure there are 4 plastic wear pads inside the inner trolley. If they became loose
during shipping, checkall packing material. Snap them backinto 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”
