An unbalanced garage door might not reverse
when required and someone under the door
could be seriously injured or killed.
If your garage door binds, sticks or is out of
balance, call for professional garage door
service. Garage doors, door springs, cables,
pulleys, brackets and their hardware are under
extreme tension and can cause serious injury
or death. Do not try to loosen, move or adjust
them yourself!
Ropes left on a garage door could cause
someone to become entangled and killed.
Remove all ropes connected to the door before
installing and operating the opener.
Identify the type and height of your door and any
special conditions that exist and any additional
materials that may be required by referring to the lists
on page 4 or page 5.
To avoid damage to the garage door and
opener, disable locks before installing and
operating the opener. Use a wood screw or nail
to hold locks in the "open" (unlocked)
position.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
Before you begin, complete the following test to
make sure your door is balanced, and is not
sticking or binding:
• Lift the door about halfway as shown. Release the
door. It should stay in place, supported entirely by
its springs.
• Raise and lower the door to see if there is any
binding or sticking.
ONE-PIECE DOOR
Before you begin, survey your garage area to
see whether any of the conditions below apply
to your installation.
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, steel, aluminum, door
with glass panels, etc).

Assembly Step 1
Assemble the T-rail &
Attach the Cable Pulley Bracket
• Place the 3 T-rail sections on a flat surface for
assembly. The end sections are identical. Make
sure the "arrow label" on the center section is
pointing toward the door.
• Insert the carriage bolts so the square bolt necks
seat in the square holes in the T-rail end sections
and pass through the round holes in T-rail center
section. Assemble lock nuts, ensure alignment and
tighten.
Make sure bolt necks are
seated in the square
holes and rails are
aligned before you
tighten lock nuts. (See
right and wrong views).
Improper assembly can
cause jerky trolley
operation, noise and/or
nuisance door reversals.

You have now finished assembling your garage door opener. Please read the following
warnings before proceeding to the installation section:
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 fiat 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.

Installation Section: Pages 12 - 27
Installation Step 1
Determine Header Bracket Location
Installation procedures vary according to
garage door types. Follow the instructions
which apply to your door.
Header
Wall
Vertical
Guideline
Finished
Ceiting
2x4
If the header bracket is not rigidly fastened to
a structural support on the header wall or
ceiling, the safety reverse system may not
work properly (see page 30). The door might
not reverse when required, and could cause
serious injury or death.
The garage door springs, cables, pulleys,
brackets and their hardware are under extreme
tension. Do not attempt to loosen, move or
adjust them yourself. Serious personal injury
or death could result. Call for professional
garage door service.
Structural
Supports
• Close the door and mark the inside
vertical centerline of the garage door.
• Extend the line onto the header wall
above the door.
Remember, you can fasten the
header bracket within 2 feet of the
left or right of the door center only if
a torsion spring or center bearing
plate is in the way; or you can attach
it to the ceiling (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 supplied) 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.
