Adjustment
Introduction
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.
•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.
To prevent damage to vehicles, be sure fully open door provides
adequate clearance.
Your garage door opener is designed with electronic controls to make
setup and adjustments easy. The adjustments allow you to program
where the door will stop in the open (UP) and close (DOWN) position.
The electronic controls sense the amount of force required to open
and close the door. The force is adjusted automatically when you
program the travel.
NOTE: If anything interferes with the door’s upward travel it will stop.
If anything interferes with the door’s downward travel, it will reverse.

2- Automatic Force Set Up
Once both the up and down positions have been manually set, the Safety Reversing Sensors will reconnect and become operational. Then, the
opener will enter a force-sensing operation by automatically moving the door open and close. The garage door opener will sound an audible and
visual alert before automatically opening and closing the door. The garage door opener will beep three times, confirming that the Automatic Force
Setup completed successfully. Adjustment is complete.
If you hear one long beep after the door attempts to move, then the Automatic Force Set Up has not completed successfully. Please start over at
step 1 of Program the Travel.

Adjustment
3- 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.
•Safety reversal system MUST be tested every month.
•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.
1With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a
2x4 laid flat) on the floor, centered under thegarage door.
2Press the remote control push button to close the door. The door
MUST reverse when it makes contact with the board.
If the door stops but does not reverse:
1. Repeat Program the Travel (seeAdjustment Step 1);
2. Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems technician.
4- Test the Protector System®
Without a properly installed safety reversing sensor, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
1Open the door. Place an obstruction in the path of thedoor.
2Press the remote control push button to close the door. The door
will not move more than an inch (2.5 cm).
The garage door opener will not close from a remote control if the
LED in either safety reversing sensor is off (alerting you to the fact
that the sensor is misaligned or obstructed).
If the garage door opener closes the door when the safety reversing
sensor is obstructed (and the sensors are no more than 6 inches [15
cm] above the floor), call for a trained door systems technician.

Maintenance
Every Month
•Manually operate door. If it is unbalanced or binding, call a
trained door systems technician.
•Check to be sure door opens and closes fully. Adjust if necessary,
page 12.
•Test the safety reversal system. Adjust if necessary, page 13.
Every Year
•Oil door rollers, bearings and hinges. The garage door opener
does not require additional lubrication. Do not grease the door
tracks.
•(If applicable) Test the battery backup and consider replacing the
battery to ensure the garage door opener will operate during an
electrical power outage.
1. Unplug the garage door opener from AC power. The battery
status LED will glow solid orange (opener is operating on
battery power) or will flash (low battery power).
2. Open and close the door using the remote control or door
control.
3. In battery backup mode, the Automatic Garage Door Lock will
unlock when the garage door is opened, and will remain
disabled until power is restored.
4. Plug in the garage door opener. Verify the battery status LED
is flashing green (battery is charging).
Every Two to Three Years
•Use a rag to wipe away the existing grease from the garage door
opener rail. Reapply a small layer of white lithium grease to the
top and underside of the rail surface where the trolley slides.
The Remote Control Battery

Automatic Garage Door Opener Safety & Maintenance
Guide
Garage Door Opener Safety – An Automatic Decision
A garage door is the largest moving object in the home. An improperly adjusted garage door and opener can exert deadly force when the
door closes – which could lead to entrapment of children or adults and subsequent injury or death.
Proper installation, operation, maintenance, and testing of the garage door and automatic opener are necessary to provide a safe, trouble-free
system. Careless operation or allowing children to play with or use garage door opener controls are also dangerous situations that can lead to tragic
results. A few simple precautions can protect your family and friends from potential harm. Please review the safety and maintenance tips in this
guide carefully and keep it for reference. Check the operation of your garage door and opener to ensure they function in a safe and trouble-free
manner. Be sure to read all Important Safety Information found in your garage door opener’s manual as it provides more details and safety
considerations than can be supplied with this guide.
Garage Door Openers are Not Toys
Discuss garage door and opener safety with your children. Explain the danger of being trapped under the door.
Stay away from a moving door.
Keep transmitters and remote controls out of reach of children. Do not let children play with
or use transmitters or other remote control devices.
The wall-mounted push button should be out of reach of children, at least 5feet from the
nearest standing surface and away from all moving parts. Mount and use the button where you
can clearly see the closing garage door.
Keep the door in sight until it completely closes when using the wall-mounted push button
or transmitter.

Routine Maintenance Can Prevent Tragedies
Make monthly inspection and testing of your garage door and opener system a part of your regular routine. Review your owner’s manual for both
the door and door opener. If you don’t have the owner’s manuals, contact the manufacturer(s) and request a copy for your specific model(s). Look for
the opener model number on the back of the power unit.
WARNING – Springs are under high tension. Only qualified individuals should adjust
them.
Visually check the door and installation:
•Starting with the door in the closed position, use the manual disconnect on the opener to
disconnect the door.
•Look for signs of wear or damage on hinges, rollers, springs, and door panels.
•These parts may require periodic lubrication. Check the owner’s manual for suggested
maintenance.
•If any signs of damage are evident, contact a trained door systems technician for
assistance.
•Verify the photoeye height is no higher than 6" from the garage floor.
Test the door for proper operation:
•Open and close the door manually using handles or suitable gripping points.
•The door should move freely and without difficulty.
•The door should balance and stay partially open 3–4 feet above the floor.
•If you detect any signs of improper operation, contact a trained door systems technician
for assistance.

Test the opener safety features:
•Reconnect the opener to the door using the manual disconnect and open the door.
•Place a 2x4 board flat in the path of the door (1) and try to close it (2). The door should
stop when it comes in contact with the 2x4 and then reverse direction.
•Block the photoelectric sensor by waving an object in front of the sensor and attempt to
close the door. The door should not close unless the wall-mounted push button is
manually held during operation.
•If the opener does not perform as described, contact a trained door systems technician
for assistance.
