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
l
opener to disconnect the door.
Look for signs of wear or damage on hinges, rollers, springs, and door panels.
l
These parts may require periodic lubrication. Check the owner's manual for
l
suggested maintenance.
If any signs of damage are evident, contact a trained door systems technician for
l
assistance.
Verify the photoeye height is no higher than 6" from the garage floor.
l
Test the door for proper operation:
Open and close the door manually using handles or suitable gripping points.
l
The door should move freely and without difficulty.
l
The door should balance and stay partially open 3–4 feet above the floor.
l
If you detect any signs of improper operation, contact a trained door systems
l
technician for assistance.
Test the opener safety features:
Reconnect the opener to the door using the manual disconnect and open the door.
l
Place a 2x4 board flat in the path of the door (1) and try to close it (2). The door
l
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
l
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
l
technician for assistance.
