ASSEMBLY STEP 1

Assemble the Rail & 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 INJURYfrom 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.
