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.
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.
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:

Test the door for proper operation:
