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.
ASSEMBLY STEP 2
FASTEN THE RAIL TO THE MOTOR UNIT
1. Insert a 1/4"-20 x 1-3/4" bolt into the cover protection bolt hole on the
back end of the rail as shown. Tighten securely with a 1/4"-20 lock nut.
DO NOT overtighten.
2. Remove the 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, flat side down onto the motor unit and align the
bracket holes with the bolt holes.
5. Fasten the "U" bracket with the previously removed bolts; DO NOT use
any power tools. The use of power tools may permanently damage the
garage door opener.
