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
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
Steps 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.
ASSEMBLY STEP 2
Fasten the Rail to the Motor Unit
1. Insert a 1/4"-20x1-3/4" bolt, washer and spacer into the cover
protection bolt hole on the back end of the rail as shown.
Install lower spacer and washer then tighten securely with a
1/4"-20 lock nut.
Do NOT overtighten.
2. Remove the two bolts from the top of the motor unit.
3. Use the carton to support the front end of the rail.
4. Place the “U” bracket, fl at side down onto the motor unit and
align the bracket holes with the bolt holes. Fasten the “U”
bracket with the previously removed bolt and lock nut; DO NOT
use any power tools. The use of power tools may permanently
damage the garage door opener.
To prevent INJURY from pinching, keep hands and fingers
away from the joints while assembling the rail.
