WARNING
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.
Ropes left on a garage door could cause
someone to become entangled and killed.

installing and operating the opener.
Operation at other than 120V 60 Hz will cause
opener malfunction and damage.
WARNING
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.
Before you begin, complete the following test to make sure your door is balanced and is not sticking or
binding. 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.
• 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.
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!

Installation Step 6
Install the Door Control
WARNING
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.
• Strip 1/4" of insulation from one end of the bell
wire; connect the wire to the two screw terminals
on the back of the Door Control by color, white to
2, and white/red to 1.
Install the Door Control (or any additional push
buttons) out of the reach of children and away
from all moving parts of the door and door
hardware, but where the garage door is visible.
Do not allow children to operate the push
button(s) or the remote control transmitter(s).
• 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. Fasten the Door
Control Button securely with 6ABx1-1/2" screws. If
installing into drywall, drill 5/32" holes and use the
anchors provided.
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.
• Run the bell wire up the wall and across the ceiling
to the opener. Use insulated staples to secure the
wire in several places. Be careful not to pierce the
wire with a staple, thereby resulting in a short.
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 Instructions
beginnning on page 16.
• Receiver terminal screws and the antenna are
located on the back panel of the opener. Position
the antenna wire as shown.
• Then connect the bell wire by color to the opener
terminal screws: white to 2 and white/red to 1.
• Remember to affix 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.

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.
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.
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.

Trouble Shooting
1. If the sending eye indicator light does not glow
steadily after installation, check for:
• 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.
• Electric power to the opener.
• A short in the white or white/black wires. These
can occur under staples or at screw terminal
connections.
• Plug in the opener. Green indicator lights in both
the sending and receiving eyes will glow steadily if
wiring connections and alignment are correct.
• Incorrect wiring between sensors and opener.
• An open wire (wire break).
If the indicator light is off in the receiving eye (and
the invisible light beam path is not obstructed),
alignment is required.
2. If the sending eye indicator light glows steadily but
the receiving eye indicator light doesn't:
• Check alignment.
• Loosen the receiving eye wing nut to allow slight
rotation of unit. Adjust sensor vertically and
horizontally until the green indicator light glows
with a steady light.
• Check for an open wire to the receiving eye.

Installation Step 11
Fasten Door Bracket & Plate
CAUTION
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.
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 Section: Pages 21 – 23
Adjustment Step 1
Adjust the UP and DOWN Limits
WARNING
Improper adjustment of the travel limits could
interfere with the proper operation of the
safety reverse system. See page 23. The door
might not reverse when required and could
seriously injure or kill someone under it.
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?
Limit
Adjustment
Screws
Left Side
Panel
• 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.
Adjustment Label
Adjustment procedures are outlined below. Run the opener through a complete travel cycle after each
adjustment.
Repeated operation of the opener during adjustment procedures may cause the motor to overheat and
shut off. Simply wait 15 minutes and try again.
Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit
adjustments.
When to Adjust the Limits
If the door does not open completely
but opens at least five feet
If the opener reverses in fully closed position
Decrease down travel. Turn the DOWN limit
adjustment screw clockwise. One turn equals 2"
of travel.
Increase up travel. Turn the UP 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 door does not close completely
If the opener lights are flashing, the Safety Reversing
Sensor is obstructed. Remove the obstruction.
Increase down travel. Turn the DOWN limit
adjustment screw counterclockwise. One turn
equals 2" of travel.
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 door still won't close completely, try lengthening
the door arm. (See page 20.)
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 Steps 1
and 2, pages 8 and 9.

Adjustment Step 2
Adjust the Force
WARNING
Too much force on the door will interfere with
the proper operation of the safety reverse
system. See page 23. The door might not
reverse properly when required and could
seriously injure or kill someone under it. Do
not increase the force beyond what is required
to close the door. Do not use the force
adjustments to compensate for a binding or
sticking garage door.
Force adjustment controls are located on the back
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.
Force Adjustment
Controls
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.

Having a Problem?
Situation
Probable Cause & Solution
1. Have you disabled all door locks? Review installation instruction warnings on page 7.
The opener doesn't
operate from either
the Door Control or
a remote control:
2. 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.)
3. Repeated operation may have tripped the overload protector in the motor. Wait
15 minutes. Try again.
4. Is there a build-up of ice or snow under the door? The door may be frozen to the
ground. Remove any restriction.
5. 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 metal
(screwdriver or coin). If the opener runs, check for a faulty wire connection at the
door control or a short under the staples.

from Door Control:
A remote control
has short range:
1. Check the battery test light. If the light is dim, change the battery.
2. Change the location of the remote control in the car.
3. A metal door, foil-backed insulation or metal garage siding will reduce the
transmission range.
4. Check to be sure the antenna on the back panel of opener extends fully downward.
Install Antenna Kit, Part No. 41A3504, to increase range.
Opener noise is
disturbing in living
quarters of home:
1. 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
eliminate the "sounding board effect" and is easy to install.
The garage door
opens and closes
by itself:
1. Check to be sure that a remote control push button is not stuck in the "down" position.
2. Remove the bell wire from the Door Control terminals and operate from a 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. Is something obstructing the door?
2. If door opens at least 5 feet, the travel limits may need to be increased. One turn
equals 2 inches of travel. See page 21.
Repeat the safety reverse test after the adjustment is complete.
3. If the door has been working properly but now doesn't open all the way, increase the
up force. See page 22.
Repeat the safety reverse test after the adjustment is complete.
The door doesn't
close completely:
1. Is something obstructing the door?
2. Review travel limits adjustment procedures on page 21.
Repeat the safety reverse test after any adjustment of door arm length, close

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
garage door serviceman to correct the problem. Do not increase the force to
operate the opener.
1. The garage door springs are broken. See above.
The opener motor
hums briefly, then
won't work:
2. The trolley may be jammed into the stop bolts. Pull or push on the door while the
motor is humming to release the jammed condition. Re-adjust the door limits (page
21) to prevent over-travel.
Repeat the safety reverse test after the adjustment is complete.
3. If the problem occurs on the first operation of the opener, door may be locked.
Disable the door lock. If the chain was removed and reinstalled, the motor may be
out of phase. Remove the chain; cycle the motor to the down position. Observe the
drive sprocket. When it turns in a clockwise direction and stops in the down position,
re-install the chain.
Repeat the safety reverse test after the adjustment is complete.
The opener won't
operate due to
power failure:
1. Use the manual release rope and handle 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 25.)
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.
The chain droops
or sags:
1. It is normal for the chain to droop slightly in the closed door position. Use the manual
release rope and handle to disconnect the trolley. If the chain returns to the normal
height when the trolley is disengaged and the door reverses on a 2x4, no
adjustments are needed (see page 7).
