To avoid installation difficulties, do not run the garage door opener until instructed to do so.
Assembly Step I I
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 Is
larger on the top of the rail than on the bottom. A
smaller hole 3- I/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-piece 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.

IMPORTANT INSTALLATION INSTRUCTIONS
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2. Install only on a properly balanced and lubricated garage door. An improperly balanced door
may not reverse and could result in severe injury or death. Repairs to cables, spring assemblies
and other hardware must be made by a professional service person before installing opener.
3. Disable all locks and remove all ropes connected to the garage door before installing the opener.
Ropes connected to a garage door can cause entanglement and death.
4. If possible, install door opener 7 feet or more above floor with the emergency release handle
mounted 6 feet above the floor.
5. Do not connect the opener to power source until instructed to do so.
6. Locate the Door Control within sight of the door at a minimum height of 5 feet where small
children cannot reach, and away from all moving parts of the door.
7. Install the User Safety Instruction Label on the wall adjacent to the door control and the
Maintenance Instruction Label in a prominent location on the inside of the garage door.
8. Upon completion of the installation, the door must reverse when it comes in contact with a
one-inch high object or a 2x4 laid flat on the floor.
9. Do not wear watches, rings or loose clothing while installing or servicing an opener. Jewelry or
loose clothing can be caught in the mechanism of the garage door or the opener.

or death could resulL Call for professional
garage door service.
• Extend the line onto the header wall
above the door.
Remember, you can fasten the header
bracket within 4 feet of the left or right
of the door center only if a torsion
spring or center bearing plate is in the
(refer to page 14) when clearance Is
minimal. (It may be mounted on the
wall upside down if necessary, to gain
approximately 1/2".)
If you need to install the header bracket
on a 2x4 (on wall or ceiling), use lag
screws (not provided) to securely fasten
the 2x4 to structural supports as shown
here and on page 13.
• Open your door to the highest
point of travel as shown. Draw
an intersecting horizontal line
on the header wall 2" above
the high point. This height will
provide travel clearance for the
top edge of the door.
Door clearance brackets are
available for sectional doors
when headroom clearance is
less than 2". See accessory
page 38.
