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
(see illustration).
The hole above this window is larger
on the top of the rail
than on the bottom. A smaller hole
3-1/2" (8.9 cm) away is close to the rail edge. Rotate the
back rail so it has a similar hole close to the
opposite
edge, about 4-3/4" (12 cm) from the far end.
1. Remove the straight door arm and hanging bracket
packaged inside the front rail and set aside for
Installation Step 5 and 12.
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.
To prevent INJURY from pinching, keep hands and fingers
away from the joints while assembling the rail.
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.
