Look at the garage door springs, cables, rollers, pulleys, and other door hardware for signs of wear. If you suspect problems, have a qualified person make repairs.
Avoid a Moving Door and Keep Hands and Fingers Clear
Do not stand, walk or run under a moving door. Hands and fingers must be kept clear from sections joints, hinges, tracks, springs and other door parts.
Do Not Let Children Play With Transmitters or Remote Controls
Garage door openers are not toys. Keep them out of the reach of children. Push-button wall controls must be mounted high enough to be out of the reach of children.
Only Operate The Door If You Can See It
Keep the door in sight until it closes completely.
Test the Reversing Mechanism Monthly
If an object obstructs the door as it is closing, the door should reverse. Make sure the garage door operator is equipped with such a reversing feature. If the door does not reverse, have it repaired or replaced by a person qualified to make repairs.
Test the Door Balance Monthly
With the door in the closed position and the operator disconnected, lift the door. It should lift smoothly and with little resistance and should remain open. If the door is out of balance, have the door system adjusted by a person qualified to make adjustments.
Test the Force Setting Monthly
Hold up the bottom of the door as it closes. If the door does not easily reverse, the force is excessive and needs adjustment by a qualified person.
