To avoid installation difficulties, do not run the garage door opener until instructed to do so.

Assembly Step 1

Assemble the Rail & Install the Trolley

The front rail has a cut out "window” at the door end (see illustration). The hole above this window 1$ larger on the top of the rail than on the bottom. A smaller hole 3-1/2" away is close to the rail edge.

The back rail has a similar hole close to the edge, about 4-3/4" from the far end. A 3-plece rail uses

two back rails.

Preferred assembly Is to position the rails right side up, with the small holes along the same

edge.

1. Remove the straight door arm and clevis pin packaged inside the front rail and set aside for Installation Step 12.

2. Align the rail sections on a flat surface exactly as shown and slide the tapered ends into the larger ones. Tabs along the side will lock into place.

3. Place the powerhead 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 trolley stop, clamp a locking pliers onto the rail, 8" from the center of the idler pulley

hole, as shown.

5. Check to be sure there are 4 black 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. Connect the inner and outer trolleys as shown.

7. Slide the trolley assembly along the rail from the back end to the locked pliers.

• Remove the two screws from the top of the opener.

• Attach spreaders to the U bracket by snapping them into place. ^

• Place the U bracket, flaTsfiJe down, on the opener

and align the bracket holes with the screw holes. Fasten with the previously removed screws.

• Align the rail assembly with the top of the opener, and slide the rail end onto the U-bracket as far as it wiii go.

To fasten raff, use only those screws mounted

in the top of the opener. Any other screws wifi cause serious damage to the opener.

Assembly Step 3

install the Idler Pulley

Lay the chain/cable beside the rail, as shown. Grasp the end with the cable loop and pass approximately 12“ of cable through the window. Allow it to hang until Assembly Step 5.

Remove the tape from the idler pulley. The inside center should be pre-greased. If dry, regrease to ensure proper operation.

Place the idler pulley into the window as shown. Insert the idler bolt from the top through the rail

and pulley. Tighten with a 3/8" lock washer and

nut underneath the rail until the lock washer is

compressed.

Rotate the pulley to be sure it spins freely. Insert a 1/4"-20x1-3/4 bolt into the trolley stop

hole in the front of the rail as shown. Tighten securely with a 1/4"-20 lock nut.
