WARNING
WARNING
CAUTION

3
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.
This product is for use on sectional garage
doors only. Serious personal injury could
result from the use of this product on one-
piece garage doors.
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.
Identify the type and height of your door, any special
conditions that exist, and any additional materials
that may be required by referring to the lists on
page 4.

Safety Reversing Sensor
Horizontal and vertical reinforcement
is needed for lightweight garage doors
(fiberglass, steel, aluminum, door with glass panels, etc.).
See page 19 for details.
Support bracket &
fastening hardware
is required.

Based on your particular requirements, there are
several installation steps which might call for
materials and/or hardware not included in the carton.
• Step 1, page 8 - Look at the wall or ceiling above
the garage door. The header bracket must be
securely fastened to structural supports.
• Step 5, page 12 - Do you have a finished ceiling in
your garage? If so, a support bracket and
additional fastening hardware may be required.
• Safety reversing sensor, page 16 - Depending
upon garage construction, wood blocks may need
to be fastened to mounting locations before
sensors are installed.
• Step 10, page 17 - Alternate floor mounting of the
safety reversing sensor will require hardware not
provided.
• Step 11, page 19 - Do you have a steel, aluminum,
fiberglass or glass panel door? If so, horizontal
and vertical reinforcement is required.
• Look at the garage door where it meets the floor.
It must close on the floor all the way across. Other-
wise, the safety reverse system may not work
properly. Floor or door should be repaired. See
page 23.
• If your door is more than 7 feet high, see longer
rails available on page 34.

• The opener can be installed within 2 feet to the left or
right of the door center if there is a torsion spring or
center bearing plate in the way of the header bracket
or door bracket area. If your door has extension
springs, the opener must be installed in the center of
the door. See pages 8 and 19.
Do you have an access door in addition to the garage
door? If not, Model 1702 Outside Quick Release is
required. See page 34.
You may find it helpful to refer back to this page as
you proceed with the installation of your opener.
Before you begin, survey your garage area. Do any of the following conditions apply to you?

CAUTION
• Position the rail support bracket on the opener.
• Attach the bracket to the rail with 1/4"-20x5/8" hex
screws and lock washers.
• Attach the bracket to the opener by inserting a
5/16"-18x1/2" washered screw through a hole in
each side flange and a matching hole in the bracket.
Complete the connection by inserting the
#8-32x3/8" screw through the back flange and the
hole in rail support.
Serious injury can result if fingers become
entangled in moving opener sprocket. Attach
rail support bracket securely. Never operate
opener while you hand is near the opener
sprocket.
WARNING

• Spin the inner nut and lock washer down the
threaded shaft, away from the trolley.
• To tighten the chain, turn outer nut in the direction
shown. As you turn the nut, keep the chain
from twisting.
• When the chain is approximately 1/2" above the
base of the rail at its midpoint, re-tighten the inner
nut to secure the adjustment.
Sprocket noise can result if chain is either too
loose or too tight.
When installation is complete, you may notice some
chain droop with the door closed. This is normal. If
the chain returns to the position shown when the
door is open, do not re-adjust the chain.
NOTE: During future maintenance, ALWAYS pull
the manual release handle to disconnect trolley
before adjusting chain.

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 manual 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 control button 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.

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

• 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.

• 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 to 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 9) 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.
Installation Section: Pages 8 – 20
Installation Step 1
Determine Header Bracket Location
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 23). 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.
