Check the Door
To prevent possible SERIOUSINJURYor DEATH:
l ALWAYS call a trained door systems technician if garage door binds, sticks, or is
out of balance. An unbalanced garage door may NOT reverse when required.
l NEVER try to loosen, move or adjust garage door, door springs, cables, pulleys,
brackets or their hardware, ALLof which are under EXTREME tension.
l Disable ALLlocks and remove ALLropes connected to garage door BEFORE
installation and operating garage door opener to avoid entanglement.
To prevent damage to garage door and opener:
l ALWAYS disable locks BEFORE installing and operating the opener.
l ONLY operate garage door opener at 120V, 60Hz to avoid malfunction and
damage.
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 floor and the
bottom of the door must not exceed 1/4inch (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 10.
