CAUTION
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.
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.
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 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.

Installation Step 1
WARNING
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 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.
Installation procedures vary according to
garage door types. Follow the instructions
which apply to your door.

under the door. Make sure the doorway is clear
of persons and obstructions before pulling
handle when door is open.
• Thread one end of the rope through the hole in
the top of the red handle so "NOTICE" reads right
side up as shown. Secure with an overhand knot.
The knot should be at least 1" from the end of
the rope to prevent slipping.
• Thread the other end of the rope through the hole
in the release arm of the outer trolley.
• Adjust rope length so the handle is 6 feet above
the floor. Secure with an overhand knot .
If it is necessary to cut the rope, heat seal the
cut end with a match or lighter to prevent
unraveling.

Electrical Requirements
To prevent electrocution or fire, installation
and wiring must be in compliance with local
electrical and building codes.
Do NOT use an extension cord, 2-wire adapter,
or change the plug in any way to make it fit
your outlet.
To reduce the risk of electric shock, your garage
door opener has a grounding type plug with a third
grounding pin. This plug will only fit into a grounding
type outlet.
If the plug doesn't fit into the outlet you have,
contact a qualified electrician to install the proper
outlet.
To avoid installation difficulties,
do not run the opener at this time.

The Safety Reversing System
Information you'll need before you begin the installation of the safety reversing sensor.
The safety reversing sensor must be connected
and aligned correctly before the garage door
opener will move in the down direction. This is a
required safety device and cannot be disabled.
WARNING
Without a properly working safety reversing
sensor, persons (particularly children) could
be injured or killed by a closing garage door.
Read and follow all instructions.
To protect small children, install the safety
reversing sensor so that the beam will be no
higher than 4"-6" above the garage floor.
Disconnect power to the garage door opener
before installing the safety reversing sensor.
Installation procedures are the same for sectional
and one-piece doors.
The brackets must be securely fastened to a solid
surface such as the studs on either side of the door,
or add a piece of wood at each location if installing in
masonry construction.
Be sure power to the opener is disconnected.
The sending eye transmits an invisible light beam to
the receiving eye. The units can be installed on
either side of the garage door as long as the sun
never shines directly into the receiving eye lens.
Look at the label on the connector end of each case
to identify the sensors.
The brackets must be connected and fastened so
that the sending and receiving eyes face each other
as shown in Figure 1.
If an obstruction breaks the light beam while the
garage door is closing, the door will stop and
reverse to full open position and the opener lights
will flash for 5 seconds.
The invisible light beam path must be unobstructed.
No part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) can interrupt the
beam while the door is closing. If it does, use a piece
of wood to build out each sensor mounting location to
the minimum depth required for light beam clearance.

Figures 2 and 3 show assembly of brackets and
"C" wrap based on the recommended installation of
the sensors as shown on page 21.
However, Figures 4 and 5 are variations which may
fit your installation requirements better. Make sure
the wraps and brackets are aligned so the
sensors will face each other across the garage
door.
• Fasten the "C" wraps to the mounting brackets
having square holes, using the hardware shown
in Figure 2.
• Connect each assembly to a slotted bracket, using
the hardware shown in Figure 3.
Note the alignment of the brackets for left and
right sides of the door.
• Finger tighten the lock nuts.
• Use bracket mounting holes as a template to
locate and drill (2) 3/16" diameter pilot holes on
both sides of the garage door, 4"-6" above the
floor but not exceeding 6". (See warning on
page 21.)
• Attach bracket assemblies with 1/4"x1-1/2" lag
screws as shown in Figure 3.

• Strip 1/4" of insulation from each set of wires.
Separate white and white/black wires sufficiently to
connect to the opener terminal screws: white to 2
and white/black to 3.
• Plug in the opener. Make sure the Lock Feature is
off. Green indicator lights in both the sending and
receiving eyes will glow steadily if wiring
connections and alignment are correct.
If the indicator light is off in the receiving eye (and
the invisible light beam path is not obstructed),
alignment is required.
• Loosen the receiving eye wing nut to allow slight
rotation of unit. Adjust sensor vertically and/or
horizontally until the green indicator light glows
with a steady light.
• When indicator lights are glowing steadily in both
units, tighten the wing nut in the receiving eye unit.

CAUTION
WARNING
To prevent damage to steel, aluminum,
fiberglass or glass panel doors, always
reinforce the inside of the door both vertically
and horizontally with an angle iron.
Follow instructions which apply to your door
type as illustrated below or on page 25.
A horizontal brace should be long enough to be secured to 2 vertical supports. A vertical brace should
cover the height of the top panel.
The illustration shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of
angle iron are used to create a "U"-shaped support. The best solution is to check with your garage door
manufacturer for an opener installation door reinforcement kit.

trolley travel.
Closed Door Adjustment:
Decrease DOWN limit
• Turn the DOWN limit adjustment screw clockwise
5 complete turns.
• Press the Wall Control push bar. The trolley will
travel to the fully closed position.
• Manually close the door and lift the door arm to the
trolley. The arm should touch the trolley just ahead
of the door arm connector hole. Refer to the fully
closed trolley/door arm positions in the illustration. If
the arm is behind the connector hole, adjust the limit
further. One full turn equals 2" of trolley travel.
Connect the door arm to the trolley.
• Close the door and join the curved arm to the connector hole in the trolley with the remaining clevis pin. It may
be necessary to lift the door slightly to make the connection.
• Secure with a ring fastener.
• Run the opener through a complete travel cycle. If the door has a slight "backward" slant in full open position
as shown in the illustration, decrease the UP limit until the door is parallel to the floor.

Adjustment Section: Pages 28 – 30
Adjustment Step 1
WARNING
Adjust the UP and DOWN Limits
Do not make any limit adjustments until the
safety reversing sensors are completely
installed.
Improper adjustment of the travel limits will
interfere with the proper operation of the
safety reverse system. The door might not
reverse properly when required and could
seriously injure or kill someone under it. Test
the safety reverse system following all
adjustments to the travel limits. See page 30.
Limit adjustment settings regulate the points at
which the door will stop when moving up or down.
The door will stop in the up direction if anything
interferes with door travel. The door will reverse in
the down direction if anything interferes with the
door travel (including binding or unbalanced doors).
To operate the opener, press the Door Control push
button. Run the opener through a complete travel
cycle.
• Does the door open and close completely?
• Does the door stay closed and not reverse
unintentionally when fully closed?
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (See page 30).

handle. Manually open and close the door. If the door
is binding, call for garage door service. If the door is
not binding or unbalanced, adjust the DOWN (close)
force. See Adjustment Step 2.
If the door does not close completely
Increase down travel. Turn the DOWN limit
adjustment screw counterclockwise. One turn
equals 2" of travel.
If door still won't close completely, try lengthening
the door arm. (See Page 26.)
If you have adjusted the door arm to the maximum
length and the door still will not close completely,
lower the header bracket. See Installation Step 1,
pages 12 and 13.
28
Adjustment Step 2
WARNING
Adjust the Force
Too much force on the door will interfere with
the proper operation of the safety reverse
system. The door might not reverse properly
when required and could seriously injure or
kill someone under it. Do not increase the
force beyond the minimum amount required
to close the door. Do not use the force
adjustments to compensate for a binding or
sticking garage door. Test the safety reverse
system following all adjustments to force
levels. See page 30.
Force adjustment controls are located on the right
side panel of the opener. Force adjustment settings
regulate the amount of power required to open and
close the door.
The door will stop in the up direction if anything
interferes with its travel. The door will reverse in the
down direction if anything interferes with its travel
(including binding or unbalanced doors).
If the forces are set too light, door travel may be
interrupted by nuisance reversals in the down
direction and stops in the up direction. Weather
conditions can affect the door movement, so
occasional adjustment may be needed.
The maximum force adjustment range is 260 degrees,
about 3/4 of a complete turn. Do not force controls
beyond that point. Turn force adjustment controls
with a screwdriver.

How and When to Adjust the Forces
Test the DOWN (close) force
Grasp the door bottom when the door is about
halfway through DOWN (close) travel. The door
should reverse. Reversal halfway through down
travel does not guarantee reversal on a two-inch
obstruction. See page 30. If the door is hard to
hold or doesn't reverse, decrease the DOWN (close)
force by turning the control counterclockwise.
Make 10 degree turn adjustments until the door
reverses normally. After each adjustment, run the
opener through a complete cycle.
Make 10 degree turn adjustments until the door stops
easily. After each adjustment, run the opener through
a complete travel cycle.
If the door doesn't open at least 5 feet
Increase UP (Open) force by turning the control
clockwise. Make 10 degree turn adjustments until
door opens completely. Re-adjust the UP limit if
necessary. After each adjustment, run the opener
through a complete travel cycle.
If the door reverses during the down (close) cycle
and the opener lights aren't flashing
Increase DOWN (close) force by turning the control
clockwise. Make 10 degree turn adjustments until the
door completes a close cycle. After each adjustment,
run the opener through a complete travel cycle. Do
not increase the force beyond the minimum
amount required to close the door.
Test the UP (open) force
Grasp the door bottom when the door is about
halfway through UP (open) travel. The door should
stop. If the door is hard to hold or doesn't stop,
decrease UP (open) force by turning the control
counterclockwise.
29
Adjustment Step 3
WARNING
Test The Safety Reversing Sensor
Without a properly working safety reversing
sensor, persons (particularly children) could be
seriously injured or killed if trapped by a closing
garage door. Repeat this test once a month.
• Press the remote control push button to open the
door.
• Place the opener carton in the path of the door.
• Press the remote control push button to close the
door. The door will not move more than an inch,
and the opener light(s) will flash.
Professional service is required if the opener
closes the door when the safety reversing
sensor is obstructed.
The garage door opener will not close from a
remote control if the indicator light in either
sensor is off (alerting you to the fact that the
sensor is misaligned or obstructed).
The garage door can be closed by pressing and
holding the Door Control push button until down
travel is completed.
Safety Reversing Sensor
Adjustment Step 4
Safety Reversing Sensor
WARNING
Test the Safety Reverse System
Failure to test and adjust the safety reverse
system may result in serious injury or death to
persons trapped by a closing garage door.
Repeat this test once a month and adjust as
needed.
Test:
• Place a one-inch board (or a 2x4 laid flat) on the
floor, centered under the garage door.
• Operate the door in the down direction. The door
must reverse on striking the obstruction.
GARAGE DOOR
Adjustment:
If the door stops on the obstruction, it is not traveling
far enough in the down direction.
• Increase the DOWN limit by turning the DOWN
limit adjustment screw counterclockwise 1/4 turn.
• Repeat the test.
On a sectional door, make sure limit
adjustments do not force the door arm beyond a
straight up and down position. See the
illustration on page 26.
• When the door reverses on the one-inch board,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.
If the door will not reverse after repeated
adjustment attempts, call for professional
garage door service.
One-inch Board
(or a 2x4 laid flat)
Important safety check
Repeat Adjustment Steps 1, 2 and 4 after:
• Each adjustment of door arm length, force controls
or limit controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.

resulting in serious injury, death or property
damage. If possible, use the emergency
release rope and handle only when the door is
fully closed.
When the opener is activated with the safety
reversing sensor installed and correctly aligned:
1. If open, the door will close. If closed, the door will
open.
2. If closing, the door will reverse.
3. If opening, the door will stop (allowing space for
entry and exit of pets and for fresh air).
4. If the door has been stopped in a partially open
position, it will close.
5. If obstructed while closing, the door will reverse.
6. If obstructed while opening, the door will stop.
7. The garage door will reverse in the closing cycle
when the invisible beam is broken. If fully open,
the door will not close when the beam is broken.
The sensor has no effect in the opening cycle.

Having a Problem?
Situation
Probable Cause and Solution
The opener doesn't
operate from either
the Door Control or
the remote control:
1. Does the opener have electric power? Plug a lamp into the outlet. If it doesn't light,
check the fuse box or the circuit breaker. (Some outlets are controlled by a door switch.)
2. Have you disabled all door locks? Review installation instruction warnings on Page 11.
3. Is there a build-up of ice or snow under the door? The door may be frozen to the
ground. Remove any restriction.
4. The garage door spring may be broken. Have it replaced.
5. Repeated operation may have tripped the overload protector in the motor. Wait
15 minutes. Try again.
Opener operates
from the remote
control, but not from
the Door Control:
1. Is the Door Control lit? If not, remove the bell wire from the opener terminal screws.
Short the red and white terminals by touching both terminals at the same time with a
piece of wire. If the opener runs, check for a faulty wire connection at the Door
Control, a short under the staples, or a broken wire.
2. Are the wiring connections correct? Review Step 6, page 18.
The door operates
from the Door
Control, but not from
the remote control:
1. If your model has the Lock feature, make sure the lock is Off.
2. Is any door push button flashing? Your opener needs to re-learn a remote control
code. Refer to Instructions on the opener panel.
3. Program the receiver to match the remote control code.
4. Repeat the receiver programming procedure with all remote controls.
The remote control
has short range:
1. Change the location of the remote control in your car.
2. Check to be sure the antenna on the side or back panel of opener extends fully
downward.
3. Some installations may have shorter range due to a metal door, foil backed
insulation, or metal garage siding.
Opener noise is
disturbing in living
quarters of home:
If operational noise is a problem because of proximity of the opener to the living
quarters, the Vibration Isolator Kit 41A3263 can be installed. This kit was designed to
minimize vibration to the house and is easy to install.
The garage door
opens and closes
by itself:
1. Be sure that all remote control push buttons are off.
2. Remove the bell wire from the Door Control terminals and operate from the remote
control only. If this solves the problem, the Door Control is faulty (replace), or there is
an intermittent short on the wire between the Door Control and the opener.
The door doesn't
open completely:
1. If the door has been working properly but now doesn't open all the way, increase the
up force. See page 29.
2. Is something obstructing the door? Remove the obstruction or repair the door.
3. If door opens at least 5 feet, the travel limits may need to be increased. One turn
equals 2 inches of travel. See page 28.
Repeat the safety reverse test after the adjustment is complete.
The door stops but
doesn't close
completely:
Review the travel limits adjustment procedures on page 28.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.
34
Having a Problem? (continued)
Situation
Probable Cause & Solution
The door opens but
won't close:
1. If the opener lights blink, check the safety reversing sensor. See page 23.
2. If the opener lights do not blink and it is a new installation, check the down force.
See Adjustment Step 2, page 29. For an existing installation, see below.
Repeat the safety reverse test after the adjustment is complete.
The door reverses for
no apparent reason
and opener lights
don't blink:
1. Is something obstructing the door? Pull the red emergency release handle. Operate
the door manually. If it is unbalanced or binding, call for professional garage door
service.
2. Clear any ice or snow from the garage floor area where the door closes.
3. Review the force adjustment procedures on page 29.
4. If door reverses in the fully closed position, decrease the travel limits (page 28).
Repeat safety reverse test after adjustments to force or travel limits. The need
for occasional adjustment of the force and limit settings is normal. Weather
conditions in particular can affect door travel.
The door reverses for
no apparent reason
and opener lights
blink for 5 seconds
after reversing:
Check the safety reversing sensor. Remove any obstruction or align the receiving eye.
See page 23.
The opener lights:
. . . don't turn on:
Replace the light bulbs (75 watts maximum). Use a standard neck garage door opener
bulb if regular bulb burns out.
. . . don't turn off:
Is the Light feature on? Turn it off.
The opener strains or
maximum force is
needed to operate
door:
The door may be out of balance or the springs are broken. Close the door and use the
emergency release to disconnect the trolley. Open and close the door manually. A properly
balanced door will stay in any point of travel while being supported entirely by its springs. If it
does not, disconnect the opener and call a professional garage door serviceman. Do not
increase the force to operate the opener.
The opener motor
hums briefly, then
won't work:
1. The garage door springs are broken. See above.
2. If the problem occurs on the first operation of the opener, door may be locked. Disable
the door lock. If the belt was removed and reinstalled, the motor may be out of phase.
Remove the belt; cycle the motor to the down position. Observe the drive sprocket.
When it turns in a clockwise direction and stops in the down position, reinstall the belt.
Repeat the safety reverse test after the adjustment is complete.
The opener won't
operate due to
power failure:
1. Use the emergency release to disconnect the trolley. The door can be opened and closed
manually. When the power is restored, press the Door Control push button and trolley will
automatically reconnect (unless trolley is in lockout position.) See page 32.
2. The Emergency Key Release accessory (for use on garages with no service door)
disconnects the trolley from outside the garage in case of power failure.
