Check the Door
To prevent possible SERIOUSINJURYor DEATH:
lALWAYS call a trained door systems technician if garage door binds, sticks, or is out of balance. An
unbalanced garage door may NOT reverse when required.
lNEVER try to loosen, move or adjust garage door, door springs, cables, pulleys, brackets or their
hardware, ALLof which are under EXTREME tension.
lDisable ALLlocks and remove ALLropes connected to garage door BEFORE installation and operating
garage door opener to avoid entanglement.
lDO NOT install on a one-piece door if using devices or features providing unattended close.
Unattended devices and features are to be used ONLY with sectional doors.
To prevent damage to garage door and opener:
lALWAYS disable locks BEFORE installing and operating the opener.
lONLY operate garage door opener at 120V, 60Hz to avoid malfunction and damage.
Before you begin:
1. Disable locks and remove any ropes connected to the garage door.
2. Lift the door halfway up. Release the door. If balanced, it should stay in place, supported entirely by
its springs.
3. Raise and lower the door to check for binding or sticking. If your door binds, sticks, or is out of
balance, call a trained door systems technician.
4. Check the seal on the bottom of the door. Any gap between the floor and the bottom of the door
must not exceed 1/4" (6 mm). Otherwise, the safety reversal system may not work properly.
5. The opener should be installed above the center of the door. If there is a torsion spring or center
bearing plate in the way of the header bracket, it may be installed within 4feet (1.2 m) to the left or
right of the door center. See page 15.

Assembly
STEP 1 Assemble the Rail and Install the Trolley
To prevent INJURY from pinching, keep hands and fingers away from the joints while assembling the rail.
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 rail tab MUST be on 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 in the second rail section from the motor
unit, 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 toward the screwdriver as shown.
7. Slide the rail onto the “U” bracket, until it reaches all the stops on the top and sides of the “U”
bracket.

STEP 2 Fasten the Rail to the Motor Unit
To avoid SERIOUS damage to garage door opener, use ONLY those bolts/fasteners mounted in the top of
the opener.
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.
