CAUTION
WARNING
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.
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 and any
special conditions that exist and any additional
materials that may be required by referring to page 4.

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.

WARNING
Install the Door Control Panel
DO NOT CONNECT TO LIVE ELECTRICAL WIRING.
CONNECT ONLY TO 24 VOLT LOW VOLTAGE
WIRES. CONNECTION TO LIVE WIRES OR HIGHER
VOLTAGE MAY CAUSE SERIOUS INJURY FROM
SHOCK, BURN OR ELECTROCUTION.
Children operating or playing with a garage door
opener can injure themselves or others. The garage
door could close and cause serious injury or death.
Do not allow children to operate the push button(s)
or the remote control transmitter(s).
A moving garage door could injure someone under
it. Activate the opener only when the door is
properly adjusted, you can see it clearly, and there
are no obstructions to door travel.
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 and
door hardware.
The door control is typically attached directly to the wall.
If installing into drywall, drill 5/32" holes and use the
anchors provided. For pre-wired installations (as in new
home construction) it can be mounted to a standard single
gang box. See illustrations.
1. Strip 1/4" of insulation from one end of the bell wire.
Connect the wire to the two screw terminals on back of
door control: white wire to 2 and white/red wire to 1.
2. Remove the push bar cover by gently prying off the top
edge with a coin or screwdriver. Fasten with 6ABx1-1/4"
self-tapping screws (standard installation) or 6-32x1"
machine screws (pre-wired installation) as follows:
• Install bottom screw, allowing 1/8" to protrude from
the wall.
• Position bottom of door control on screw head and
adjust for snug fit.
• Install top screw with care to avoid cracking plastic
housing. Do not overtighten.
3. (For standard wall mount only)
Run the bell wire up wall and across ceiling to opener.
Use insulated staples to secure the wire in several
places. Be careful not to pierce the wire with a staple,
creating a short.
4. Connect the bell wire to the terminal screws on the
opener panel: white to 2 and white/red to 1.
5. After testing, replace the cover by inserting top tabs
and snapping into place.
NOTE: After installation, the green indicator light behind the
push bar cover will indicate proper connection.
The automatic light feature will become functional 1-1/2
minutes after power is restored.
6. Attach the User Safety Instruction label to the wall near
the door control, and the Maintenance Instruction label
in a prominent location on the inside of the garage
door.
Page 28 explains how to use the door control.
Do NOT connect the power and operate the
opener at this time. The trolley will travel to the
full open position but will not return to the close
position until the sensor beam is connected and
properly aligned. See Safety Reversing Sensor

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.

IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
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.
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.
When properly connected and aligned, the safety
reversing sensor will detect an obstacle in the path of
its electronic beam. The sending eye (with an orange
indicator light) transmits an invisible light beam to the
receiving eye (with a green indicator light). If an
obstruction breaks the light beam while the door is
closing, the door will stop and reverse to full open
position, and the door control will flash for 5 seconds.
The units must be installed inside the garage so that
the sending and receiving eyes face each other
across the door, between 4 – 6" above the floor.
Either can be installed on the left or right of the door
as long as the sun never shines directly into the
receiving eye lens.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.
If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface
such as the wall framing. Extension brackets (see
accessories) are available if needed. If installing in
masonry construction, add a piece of wood at each
location to avoid drilling extra holes in masonry if
repositioning is necessary.
The invisible light beam path must be unobstructed.
No part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) may interrupt the
beam while the door is closing.

MOUNTING AND WIRING THE SAFETY SENSORS
• Slide a 1/4"-20x1/2" carriage bolt head into the slot
on each sensor. Use wing nuts to fasten sensors to
brackets, with lenses pointing toward each other
across the door. Be sure the lens is not obstructed
by a bracket extension. See Figure 5.
• Finger tighten the wing nuts.
• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.
• 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.

TROUBLESHOOTING THE SAFETY SENSORS
1. If the sending eye indicator light does not glow
steadily after installation, check for:
• Electric power to the opener.
• A short in the white or white/black wires. These
can occur at staples, or at screw terminal
connections.
• Incorrect wiring between sensors and opener.
• A broken wire.
2. If the sending eye indicator light glows steadily but
the receiving eye indicator light doesn't:
• Check alignment.
• Check for an open wire to the receiving eye.
3. If the receiving eye indicator light is dim, realign
either sensor.
NOTE: When the invisible beam path is obstructed or
misaligned while the door is closing, the door will
reverse. If the door is already open, it will not close.
The door control will blink 10 times. See page 17.
ALIGNING THE SAFETY SENSORS
• Plug in the opener. The indicator lights in both the
sending and receiving eyes will glow steadily if
wiring connections and alignment are correct.
The sending eye orange indicator light will glow
regardless of alignment or obstruction. If the green
indicator light in the receiving eye is off, dim, or
flickering (and the invisible light beam path is not
obstructed), alignment is required.
• Loosen the sending eye wing nut and readjust,
aiming directly at the receiving eye. Lock in place.
• Loosen the receiving eye wing nut and adjust
sensor until it receives the sender’s beam. When
the green indicator light glows steadily, tighten the
wing nut.

WARNING
Fasten Door Bracket
To prevent damage to steel, aluminum,
fiberglass or glass panel doors, always
reinforce the inside of the door both vertically
and horizontally with angle iron.
Follow instructions which apply to your door type
as illustrated below or on page 21.
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.

Adjustment Procedures for One-Piece Doors
Open Door Adjustment:
Decrease UP limit
• Turn the UP limit adjustment screw counterclockwise 5-1/2 turns.
• Press the Door Control push bar. The trolley will
travel to the fully open position.
• Manually raise the door to the open position
(parallel to the floor), and lift the door arm to the
trolley. The arm should touch the trolley just in
back of the door arm connector hole. Refer to the
fully open trolley/door arm positions in the
illustration. If the arm does not extend far enough,
adjust the limit further. One full turn equals 2" of
trolley travel.
Closed Door Adjustment:
Decrease DOWN limit
• Turn the DOWN limit adjustment screw clockwise 5
complete turns.
• Press the Door 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 24 – 26
Adjustment Step 1
WARNING
Adjust the UP and DOWN Limits
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 26.
Do not make any limit adjustments until the
safety reversing sensors are completely
installed.
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
bar. 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 26).

and try again.
Read the procedures carefully before continuing on
to Adjustment Step 2. Use a screwdriver to make
limit adjustments.
Limit
Adjustment
Screws
Adjustment Label
How and When to Adjust the Limits
• If the door does not open completely, but
opens at least five feet:
Increase up travel. Turn the UP limit adjustment
screw clockwise. One turn equals 2" of travel.
NOTE: To prevent the trolley from hitting the
cover protection bolt, keep a minimum distance
of 2-4" between the trolley and the bolt.
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 8 and 9.
• If the opener reverses in fully closed position:
Decrease down travel. Turn the DOWN limit
adjustment screw clockwise. One turn equals 2" of
travel.
• If door does not open at least 5 feet:
Adjust the UP (open) force as explained in
Adjustment Step 2.
• If the door reverses when closing and there is
no visible interference to travel cycle:
If the opener lights are flashing, the Safety Reversing
Sensors are either not installed, misaligned, or
obstructed. See Troubleshooting, page 19.
Test the door for binding: Pull the manual release
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 the door still won't close completely and the trolley
bumps into the pulley bracket (see page 4), try
lengthening the door arm (see page 22).
24
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 26.
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
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.
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 one-inch
obstruction. See page 26. 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.
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. Make 10 degree turn adjustments
until the door stops easily. After each adjustment,
run the opener through a complete travel cycle.

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 lights 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 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 bar until down travel
is completed.

WARNING
Test the Safety Reverse System
Failure to test and adjust the safety reverse
system may result in serious injury or death to
perons trapped by a closing garage door.
Repeat this test once a month and adjust as
needed.
Test:
• With the door fully open, place 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.
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 22.
• When the door reverses on the 2x4 laid flat,
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.
Important safety check:
2x4 laid flat
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.

1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Do not permit children either to operate or to play with the opener. Keep remote control in a
location inaccessible to children.
3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in
sight until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. Check safety reversal system monthly. See page 26. The garage door MUST reverse on contact
with a one-inch object (or a 2x4 board laid flat) placed on the floor. If an adjustment is made to
either the force or the limit of travel, both adjustments may be needed and the safety reversal
system must be checked. Failure to properly adjust the opener may result in severe injury or death.
5. If possible, use the manual release only when the door is in a closed position. Caution should be
taken whenever the disconnect cord is actuated with the door open. Weak or broken springs may
cause the door to fall rapidly, causing injury or death to persons.
6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not
reverse when required and could result in severe injury or death. Repairs to cables, spring
assemblies and other hardware must be made by a professional garage door person.
7. Disconnect the electric power from the garage door opener before making any repairs or removing
the covers.

Operation of Your Opener
Activate the opener with any of the following:
• The Remote Control Transmitter. Hold push button
down until the door starts to move.
• The Door Control. Hold push bar down until the door
starts to move.
• The Outside Keylock or Keyless Entry.
(See Accessories)
When the opener is activated:
1. If open, the door will close. If closed, it 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. If the
obstruction interrupts the sensor beam, the opener lights
will blink for 5 seconds.
6. If obstructed while opening, the door will stop.
7. If fully open, the door will not close when the beam is
broken. The sensor has no effect in the opening cycle.
If the sensor is not correctly installed and aligned, the door
won't close from any remote control transmitter. You can
close the door with the Door Control, the Outside Keylock,
or Keyless Entry, however, if you activate them until down
travel is complete. If you release them too soon, the door
will reverse.
WARNING
Weak or broken springs could allow an open
door to fall (either rapidly or unexpectedly),
resulting in serious injury, death or property
damage. If possible, use the manual release rope
and handle only when the door is fully closed.
One blink indicates that the timer is reset to 1-1/2 minutes.
Repeat the procedure and the light will blink twice,
resetting the timer to 2-1/2 minutes. Repeat again for a
3-1/2 minute interval, etc., up to a maximum of four blinks
and 4-1/2 minutes.
Automatic Light Feature: The opener light will turn on
automatically when a person enters the garage. When a
person walks in front of the door control, the light will come
on for five minutes, then shut off. This feature works by
detecting body heat and may not work in temperatures
around 100˚F.
To disable this feature, slide the Detector Switch on the
right side of the door control down (off).
We recommend that you disable the motion sensor when
using the opener lights as working lights. Otherwise, they
will turn off automatically if you are working beyond the
sensor’s range.
Energy Saving Feature: This door control senses the
brightness inside the garage, and will not turn the light on if
it is already bright enough. If the light sensor turns on the
light when it is not needed or does not turn it on when it is
dark, the sensitivity can be adjusted. Remove the push bar
cover by gently prying off the top edge with a coin or
screwdriver. Underneath there is a dial below the red light
on the right side. Use a small screwdriver to turn the dial
toward “L” (counterclockwise) to make the light come on, or
toward “H” (clockwise) to make the light go off. Replace the
cover by inserting top tabs and snapping into place.
Lock Feature: Designed to prevent operation of the door
from portable remote controls. However, the door will open
and close from the Door Control push bar and from the
Outside Keylock and the Keyless Entry accessories.
To activate: Press and hold the Lock button for 2 seconds.

Having a Problem?
Situation
Probable Cause & 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 wall switch.)
2. Have you disabled all door locks? Review installation instruction warnings on page 7.
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 1. Is the door control lit? If not, remove the bell wire from the opener terminals. Short the
the remote, but not
red and white terminals by touching both terminals at the same time with a piece of
from Door Control:
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 14.
The door operates
from the Door
Control, but not from
the remote control:
1. Is the door push bar flashing? If your model has the Lock feature, turn it off.
2. 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
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.
3. Clear memory and reprogram all remote controls.
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 25.
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 24.
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 24.
Repeat the safety reverse test after any adjustment of door arm length, close
force or down limit.
30
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 19.
2. If the opener lights do not blink and it is a new installation, check the down force.
See Adjustment Step 2, page 25. 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 manual 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 25.
4. If door reverses in the fully closed position, decrease the travel limits (page 24).
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 19.
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
manual 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 manual release to disconnect the trolley. The door can be opened and
closed manually. When the power is restored, press the Door Control push bar and
trolley will automatically reconnect (unless trolley is in lockout position.) See page 28.
2. The Outside Quick Release accessory (for use on garages with no service door)
disconnects the trolley from outside the garage in case of power failure.
