Assemble the Rail and Install the Trolley
To avoid installation difficulties, do not run the garage door
opener until instructedto do so.
The front rail has a cut out "window" at the door end
(see illustration). The hole above this windowis larger on the
top of the raft 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 oppositeedge, about 4-3/4" (12 cm)
from the far end.
1. Assemble the trolley by sliding the inner trolley into the outer
trolley.
2. Removethe straight door arm and hanging bracket packaged
inside the front rail and set aside for Installation Steps 5 and 9.
NOTE: To prevent INJURY while unpacking the rail carefully
remove the straight door arm stored within the rail section.
3. 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.
4. Placethe 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.
5. As a temporary stop, insert a screwdriver into the hole
10" (25 cm) from the front end of the rail, as shown.
6. Checkto 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.
7. Slide the trolley assembly along the rail from the back end to
the screwdriver.
To prevent INJURY from pinching, keep hands and fingers
away from the joints while assembling the rail.
