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.

• Do you have an access door in addition to the  
garage door? If not, Model 1702LM Outside Quick  
Release is required. See Accessories page.  
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.  
• 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.  
SECTIONAL DOOR INSTALLATIONS  
• Installation Step 1 – Look at the wall or ceiling  
above the garage door. The header bracket must  
be securely fastened to structural supports.  
• Do you have a steel, aluminum, fiberglass or glass  
panel door? If so, horizontal and vertical reinforce-  
ment 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.

WARNING  
Without a properly working safety reversal system,  
persons (particularly small children) could be  
SERIOUSLY INJURED or KILLED by a closing garage  
door.  
• The gap between the bottom of the garage door and  
the floor MUST NOT exceed 1/4" (6 mm). Otherwise,  
the safety reversal system may not work properly.  
• The floor or the garage door MUST be repaired to  
eliminate the gap.  
ONE-PIECE DOOR INSTALLATIONS  
• Generally, a one-piece door does not require  
reinforcement. If your door is lightweight, refer to  
the information relating to sectional doors in  
Installation Step 11.  
• Depending on your door’s construction, you may  
need additional mounting hardware for the door  
bracket (Step 11).

INSTALLATION STEP 10  
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.  
• Install the safety reversing sensor so beam is NO  
HIGHER than 6" (15 cm) above garage floor.  
IMPORTANT INFORMATION ABOUT  
THE SAFETY REVERSING SENSOR  
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 1/4" (6 mm) 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 (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 terminal connections.  
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.  
• 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:  
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 alignment.  
• Check for an open wire to the receiving eye.  
3. If the receiving eye indicator light is dim, realign  
either sensor.  
• Loosen the sending eye wing nut and readjust,  
aiming directly at the receiving eye. Lock in place.  
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. (If bulbs are not  
installed, 10 clicks can be heard.) See page 21.  
• 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.

- Turn the UP limit adjustment screw counter-  
clockwise 5-1/2 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  
equals 2" (5 cm) of trolley travel.  
• 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.  
• Closed door adjustment: decrease DOWN  
travel limit  
- Turn the DOWN limit adjustment screw  
clockwise 5 complete turns.

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.  
• After ANY adjustments are made, the safety reversal  
system MUST be tested. Door MUST reverse on  
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid  
flat) on floor.  
• 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 (Adjustment Step 3, page 30).  
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.

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 23.  
If door still won't close completely and the trolley  
bumps into the pulley bracket (page 4), try  
lengthening the door arm (page 26) 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.

ADJUSTMENT STEP 2  
WARNING  
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" (3.8 cm) high 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  
1. Test the DOWN (close) force  
Force Adjustment Controls  
• 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 30.

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.  
• 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  
BACK PANEL  
adjustment, run the opener through a complete  
travel cycle. Do not increase the force beyond the  
minimum amount required to close the door.

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" (3.8 cm) high 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 26.  
• 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.  
IMPORTANT SAFETY CHECK:  
Repeat Adjustment Steps 1, 2 and 3 after:  
• Each adjustment of door arm length, limits, or  
force controls.  
• Any repair to or adjustment of the garage door  
(including springs and hardware).  
1-1/2" (3.8 cm) board  
(or a 2x4 laid flat)  
• Any repair to or buckling of the garage floor.  
• Any repair to or adjustment of the opener.

Having a Problem? (Continued)  
6. The garage door opens and closes by itself:  
• Be sure that all remote control push buttons are  
off.  
• Check the safety reversing sensor. Remove any  
obstruction or align the receiving eye. See  
Installation Step 10.  
• 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 motor unit.  
12. The opener lights don't turn on:  
• Replace the light bulbs (75 watts maximum). Use  
A19 standard neck garage door opener bulb if  
regular bulb burns out.  
• Clear memory and re-program all remote controls.  
13. The opener lights don't turn off:  
7. The door doesn't open completely:  
• Is the Light feature on? Turn it off.  
• Is something obstructing the door? Is it out of  
balance, or are the springs broken? Remove the  
obstruction or repair the door.  
14. The opener strains or maximum force is  
needed to operate door:  
• The door may be out of balance or the springs  
may be broken. Close the door and use the  
emergency release handle 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  
trained door systems technician. Do not increase  
the force to operate the opener.  
• If the door is in good working order but now  
doesn't open all the way, increase the up force.  
See Adjustment Step 2.  
• If the door opens at least 5 feet (1.5 m), the travel  
limits may need to be increased. One turn equals  
2" (5 cm) of travel. See Adjustment Step 1.  
Repeat the safety reverse test after the adjustment is  
complete.  
8. The door stops but doesn't close completely:  
15. The opener motor hums briefly, then won't  
work:  
• Review the travel limits adjustment procedures on  
page 28.  
• The garage door springs may be broken. See  
above.  
Repeat the safety reverse test after any adjustment  
of door arm length, close force or down limit.  
• If the problem occurs on the first operation of the  
opener, door may be locked. Disable the door lock.  
9. The door opens but won't close:  
Repeat the safety reverse test after the adjustment is  
complete.  
• If the opener lights blink, check the safety  
reversing sensor. See Installation Step 10.  
16. The opener won't operate due to power  
failure:  
• If the opener lights don’t blink and it is a new  
installation, check the down force. See Adjustment  
Step 2, page 29. For an existing installation, see  
below.  
• Use the emergency release handle to disconnect  
the trolley. The door can be opened and closed  
manually. When power is restored, press the Door  
Control push bar and trolley will automatically  
reconnect (unless trolley is in lockout position.)  
See page 32.  
Repeat the safety reverse test after the adjustment  
is complete.  
10. The door reverses for no apparent reason and  
opener lights don’t blink:  
• 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.  
• Is something obstructing the door? Pull the  
emergency release handle. Operate the door  
manually. If it is unbalanced or binding, call a  
trained door systems technician.  
17. The chain droops or sags:  
• Clear any ice or snow from the garage floor area  
where the door closes.  
• It is normal for the chain to droop slightly in the  
closed door position. Use the emergency 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 laid  
flat, no adjustments are needed. (See page 11.)  
• Review Adjustment Step 2 on page 29.  
• If door reverses in the fully closed position,  
decrease the travel limits (Adjustment Step 1).  
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.
