Assembly; Assemble The Rail And Install The Trolley; Fasten The Rail To The Motor Unit - Craftsman SMART CONTROL Manual Del Propietário

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.
