Assemble The Rail And Install The Trolley; Fasten The Rail To The Motor Unit - Craftsman CMXEOCG231 Owner's Manual

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 2-1/2" 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.
6. Attach chain spreader to the motor unit with two screws.
