ASSEMBLY STEP 1
Assemble the Rail and Install the Trolley
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 front
rail has a rail tab. This tab MUST be on the 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 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 along the rail from the back end
to the screwdriver.
7. Slide the rail onto the “U” bracket, until it reaches all the
stops on the top and sides of the “U” bracket.
To prevent INJURY from pinching, keep hands and fingers away
from the joints while assembling the rail.
