Preparing your garage door
WARNING
Before you begin:
To prevent possible SERIOUS INJURY or DEATH:
• Disable locks.
• ALWAYS call a trained door systems technician if
garage door binds, sticks, or is out of balance. An
unbalanced garage door may not reverse when
required.
• NEVER try to loosen, move or adjust garage door, door
springs, cables, pulleys, brackets or their hardware, all
of which are under EXTREME tension.
• Disable ALL locks and remove ALL ropes connected to
garage door BEFORE installing and operating garage
door opener to avoid entanglement.
• Remove any ropes connected to garage door.
• Complete the following test to make sure your
garage door is balanced and is not sticking or
binding:
1. Lift the door about halfway as shown. Release
the door. If balanced, it should stay in place,
supported entirely by its springs.
2. Raise and lower the door to see if there is any
binding or sticking.
If your door binds, sticks, or is out of balance, call a
trained door systems technician.
CAUTION
To prevent damage to garage door and opener:
• ALWAYS disable locks BEFORE installing and operating
the opener.
• ONLY operate garage door opener at 120V, 60 Hz to
avoid malfunction and damage.

Planning
Identify the type and height of your garage door.
Survey your garage area to see if any of the
conditions below apply to your installation. Additional
materials may be required. You may find it helpful to
refer back to this page and the accompanying
illustrations as you proceed with the installation of
your opener.
• Do you have an access door in addition to the
garage door? If not, Model 7702CB Emergency
Key Release is required. See Accessories page.
• Look at the garage door where it meets the floor.
Any gap between the floor and the bottom of the
door must not exceed 1/4" (6 mm). Otherwise, the
safety reversal system may not work properly. See
Adjustment Step 3. Floor or door should be
repaired.
Depending on your requirements, there are several
installation steps which may call for materials or
hardware not included in the carton.
• Installation Step 1 – Look at the wall or ceiling
above the garage door. The header bracket must
be securely fastened to structural supports.
SECTIONAL DOOR INSTALLATIONS
• Do you have a steel, aluminum, fiberglass or glass
panel door? If so, horizontal and vertical
reinforcement is required (Installation Step 11).
• Installation Step 5 – Do you have a finished ceiling
in your garage? If so, a support bracket and
additional fastening hardware may be required.
• The opener should be installed above the center of
the door. If there is a torsion spring or center
bearing plate in the way of the header bracket, it
may be installed within 4 feet (1.22 m) to the left or
right of the door center. See Installation Steps 1
and 11.
• Installation Step 10 – Depending upon garage
construction, extension brackets or wood blocks
may be needed to install sensors.
• Installation Step 10 – Alternate floor mounting of
the safety reversing sensor will require hardware
not provided.
• If your door is more than 7 feet (2.13 m) high, see
rail extension kits listed on Accessories page.

CAUTION
Assemble the Rail & Install the Trolley
To prevent INJURY from pinching, keep hands and
fingers away from the joints while assembling the rail.
To avoid installation difficulties, do not run the
garage door opener until instructed to do so.
The front rail has a cut out “window” at the door end
(see illustration). The hole above this window is
larger on the top of the rail than on the bottom. A
smaller hole 3-1/2" (8.9 cm) away is close to the rail
edge. Rotate the back rail so it has a similar hole
close to the opposite edge, about 4-3/4" (12 cm)
from the far end.
3. Place the motor unit on packing material to protect
the cover, and rest the back end of the rail on top.
For convenience, put a support under the front
end of the rail.
4. As a temporary trolley stop, insert a screwdriver
into the hole 10" (25 cm) away from the front of
the rail, as shown.
1. Remove the straight door arm and hanging
bracket packaged inside the front rail and set
aside for Installation Step 5 and 12. NOTE: To
prevent INJURY while unpacking the rail carefully
remove the straight door arm stored within the rail
section.
5. Check to be sure there are 4 plastic wear pads
inside the inner trolley. If they became loose
during shipping, check all packing material. Snap
them back into position as shown.
6. Slide the trolley assembly along the rail from the
back end to the screwdriver.
2. Align the rail sections on a flat surface as shown
and slide the tapered ends into the larger ones.
Tabs along the side will lock into place.

WARNING
®
Install The Protector System
Be sure power is not connected 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.
To prevent SERIOUS INJURY or DEATH from a closing
garage door:
• Correctly connect and align the safety reversing
sensor. This required safety device MUST NOT be
disabled.
IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
• Install the safety reversing sensor so beam is NO
HIGHER than 6" (15 cm) above garage floor.
When properly connected and aligned, the sensor
will detect an obstacle in the path of its electronic
beam. The sending eye (with an amber 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 opener lights will flash 10 times.
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 units must be installed inside the garage so that
the sending and receiving eyes face each other
across the door, no more than 6" (15 cm) 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 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.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.

• Finger tighten the wing nuts.
• Run the wires from both sensors to the opener. Use
insulated staples to secure wire to wall and ceiling.
TROUBLESHOOTING THE SAFETY
REVERSING SENSORS
• Strip 7/16" (11 mm) of insulation from each set of
wires. Separate white and white/black wires
sufficiently to connect to the opener quick-connect
terminals. Twist like colored wires together. Insert
wires into quick-connect holes: white to white and
white/black to grey (Figure 6).
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 opener connections.
• Incorrect wiring between sensors and opener.
• A broken wire.
ALIGNING THE SAFETY REVERSING 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.
2. If the sending eye indicator light glows steadily but
the receiving eye indicator light doesn't:
• Check alignment.
The sending eye amber 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.
• 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 opener lights will blink 10 times. See page 20.
• 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.

arm to the trolley, the travel limits must be
adjusted. Limit adjustment screws are located on
the left side panel as shown on page 27. Follow
adjustment procedures below.
- 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" (5 cm) of trolley travel.
• Open door adjustment: decrease UP
travel limit
- Turn the UP limit adjustment screw
counter-clockwise 4 turns.
3. 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.
- Press the Door Control push button. 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

• 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.
NOTE: When setting the up limit on the following
page, the door should not have a “backward” slant
when fully open as illustrated below. A slight
backward slant will cause unnecessary bucking
and/or jerking operation as the door is being opened
or closed from the fully open position.

ADJUSTMENT STEP 1
WARNING
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
• Incorrect adjustment of garage door travel limits will
interfere with proper operation of safety reversal
system.
Adjust the UP and DOWN Travel
Limits
Limit adjustment settings regulate the points at which
the door will stop when moving up or down.
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?
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• Does the door stay closed and not reverse
unintentionally when fully closed?
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" high (3.8 cm) object (or 2x4 laid
flat) on floor.
If your door passes both of these tests, no limit
adjustments are necessary unless the reversing test
fails (Adjustment Step 3, page 29).
Adjustment procedures are outlined below. Read the
procedures carefully before proceeding to
Adjustment Step 2. Use a screwdriver to make limit
adjustments. Run the opener through a complete
travel cycle after each adjustment.
CAUTION
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.
NOTE: Repeated operation of the opener during
adjustment procedures may cause the motor to
overheat and shut off. Simply wait 15 minutes and
try again.
Cover Protection Bolt
NOTE: If anything interferes with the door’s upward
travel, it will stop. If anything interferes with the
door’s downward travel (including binding or
unbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE LIMITS
• If the door does not open completely but opens
at least five feet (1.5 m):
Limit Adjustment Screws
Left Side Panel
Increase up travel. Turn the UP limit adjustment
screw clockwise. One turn equals 2" (5 cm) of
travel.
NOTE: To prevent the trolley from hitting the cover
protection bolt, keep a minimum distance of 2-4"
(5 cm - 10 cm) between the trolley and the bolt.
ADJUSTMENT LABEL
• If door does not open at least 5 feet (1.5 m):
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:
Increase down travel. Turn the down limit
adjustment screw counterclockwise. One turn
equals 2" (5 cm) of travel.
If the opener lights are flashing, the Safety
Reversing Sensors are either not installed,
misaligned, or obstructed. See Troubleshooting,
page 22.
If door still won't close completely and the trolley
bumps into the pulley bracket (page 4), try
lengthening the door arm (page 25) and
decreasing the down limit.
Test the door for binding: Pull the emergency
release handle. Manually open and close the door.
If the door is binding or unbalanced, call for a
trained door systems technician. If the door is
balanced and not binding, adjust the DOWN
(close) force. See Adjustment Step 2.
• If the opener reverses in fully closed position:
Decrease down travel. Turn the down limit
adjustment screw clockwise. One turn equals 2"
(5 cm) of travel.

Adjust the Force
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
Force adjustment controls are located on the back
panel of the motor unit. Force adjustment settings
regulate the amount of power required to open and
close the door.
• Too much force on garage door will interfere with
proper operation of safety reversal system.
• NEVER increase force beyond minimum amount
required to close garage door.
• NEVER use force adjustments to compensate for a
binding or sticking garage door.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" high (3.8 cm) object (or 2x4 laid
flat) on floor.
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 about
3/4 of a complete turn. Do not force controls
beyond that point. Turn force adjustment controls
with a screwdriver.
NOTE: If anything interferes with the door’s upward
travel, it will stop. If anything interferes with the
door’s downward travel (including binding or
unbalanced doors), it will reverse.
HOW AND WHEN TO ADJUST THE FORCES
Force
Adjustment
Controls
1. 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 1-1/2"
(3.8 cm) obstruction. See Adjustment Step 3,
page 29. If the door is hard to hold or doesn't
reverse, DECREASE the DOWN (close) force by
turning the control counterclockwise. Make small
adjustments until the door reverses normally.
After each adjustment, run the opener through a
complete cycle.
Back Panel
KG
KG
• 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 small 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.
Antenna
2. 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 small
adjustments until the door stops easily and opens
fully. After each adjustment, run the opener
through a complete travel cycle.

ADJUSTMENT STEP 3
WARNING
Test the Safety Reversal System
Without a properly installed safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
TEST
• With the door fully open, place a 1-1/2" (3.8 cm)
board (or a 2x4 laid flat) on the floor, centered
under the garage door.
• Safety reversal system MUST be tested every month.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" high (3.8 cm) object (or 2x4 laid
flat) on the floor.
• Operate the door in the down direction. The door
must reverse on striking the obstruction.
ADJUST
• 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.
NOTE: 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 25.
• Repeat the test.
• When the door reverses on the 1-1/2" (3.8 cm)
board, remove the obstruction and run the opener
through 3 or 4 complete travel cycles to test
adjustment.
• If the unit continues to fail the Safety Reverse Test,
call for a trained door systems technician.
IMPORTANT SAFETY CHECK:
Test the Safety Reverse System after:
• Each adjustment of door arm length, limits, or
force controls.
1-1/2" (3.8 cm) board
(or a 2x4 laid flat)
• 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.
WARNING
Without a properly installed safety reversing sensor,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage
door.
ADJUSTMENT STEP 4
®
Test The Protector System
(Safety Reversing Sensors)
• 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
(2.5 cm), and the opener lights will flash.
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).
If the opener closes the door when the safety
reversing sensor is obstructed (and the sensors
are no more than 6" (15 cm) above the floor), call
for a trained door systems technician.

originally installed, that it is free from defect in materials and/or workmanship for a period of one year from the date of purchase [and
that the motor is free from defect in materials and/or workmanship for a period of six years from the date of purchase]. The proper

toll free, before dismantling this product. Then send this product, pre-paid and insured, to our service center for warranty repair. You
will be advised of shipping instructions when you call. Please include a brief description of the problem and a dated proof-of-
purchase receipt with any product returned for warranty repair. Products returned to Seller for warranty repair, which upon receipt by
Seller are confirmed to be defective and covered by this limited warranty, will be repaired or replaced (at Seller’s sole option) at no
cost to you and returned pre-paid. Defective parts will be repaired or replaced with new or factory-rebuilt parts at Seller’s sole option.
ALL IMPLIED WARRANTIES FOR THE PRODUCT, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN DURATION TO THE ONE-YEAR LIMITED
WARRANTY PERIOD SET FORTH ABOVE [EXCEPT THE IMPLIED WARRANTIES WITH RESPECT TO THE MOTOR, WHICH
ARE LIMITED IN DURATION TO THE SIX-YEAR LIMITED WARRANTY PERIOD FOR THE MOTOR], AND NO IMPLIED
WARRANTIES WILL EXIST OR APPLY AFTER SUCH PERIOD. Some States do not allow limitations on how long an implied
warranty lasts, so the above limitation may not apply to you. THIS LIMITED WARRANTY DOES NOT COVER NON-DEFECT
DAMAGE, DAMAGE CAUSED BY IMPROPER INSTALLATION, OPERATION OR CARE (INCLUDING, BUT NOT LIMITED TO
ABUSE, MISUSE, FAILURE TO PROVIDE REASONABLE AND NECESSARY MAINTENANCE, UNAUTHORIZED REPAIRS OR
ANY ALTERATIONS TO THIS PRODUCT), LABOR CHARGES FOR REINSTALLING A REPAIRED OR REPLACED UNIT,

CALL THAT DETERMINES THE PROBLEM HAS BEEN CAUSED BY ANY OF THESE ITEMS COULD RESULT IN A FEE TO YOU.
UNDER NO CIRCUMSTANCES SHALL SELLER BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL OR SPECIAL DAMAGES
ARISING IN CONNECTION WITH USE, OR INABILITY TO USE, THIS PRODUCT. IN NO EVENT SHALL SELLER’S LIABILITY
FOR BREACH OF WARRANTY, BREACH OF CONTRACT, NEGLIGENCE OR STRICT LIABILITY EXCEED THE COST OF THE
PRODUCT COVERED HEREBY. NO PERSON IS AUTHORIZED TO ASSUME FOR US ANY OTHER LIABILITY IN CONNECTION
WITH THE SALE OF THIS PRODUCT.
Some States do not allow the exclusion or limitation of consequential, incidental or special damages, so the above limitation or
exclusion may not apply to you. This limited warranty gives you specific legal rights, and you may also have other rights which vary
