Word Review
This garage door opener has been designed 
and tested to offer safe service provided it is 
installed, operated, maintained and tested in 
strict accordance with the instructions and 
warnings contained in this manual.
When you see these Safety Symbols and 
Signal Words on the following pages, they 
will alert you to the possibility of serious 
injury or death
 if you do not comply 
with the warnings that accompany them. 
The hazard may come from something 
mechanical or from electric shock. Read the 
warnings carefully.
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.

   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.

   Check the seal on the bottom of the 
door. Any gap between the fl oor and 
the bottom of the door must not exceed 
1/4 inch (6 mm). Otherwise, the safety 
reversal system may not work properly.

   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 Installing the Header 
Bracket section.
