Check the Door
Before you begin:
1. Disable locks and remove any ropes connected to the garage door.
2. Lift the door halfway up. Release the door. If balanced, it should stay in place, supported entirely by its
springs.
3. Raise and lower the door to check for binding or sticking. If your door binds, sticks, or is out of balance,
call a trained door systems technician.
4. Check the seal on the bottom of the door. Any gap between the oor and the bottom of the door must not
exceed 1/4” (6 mm). Otherwise, the safety reversal system may not work properly.
5. 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 (1.2 m) to the left or right of the
door center. See page 15.
