Adjustments

Introduction
Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY
INJURED or KILLED by a closing garage door.
Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal
l
system.
After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on
l
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.
To prevent damage to vehicles, be sure fully open door provides adequate clearance.
Your garage door opener is designed with electronic controls to make setup and adjustments easy. The adjustments
allow you to program where the door will stop in the open (UP) and close (DOWN) position. The electronic controls
sense the amount of force required to open and close the door. The force is adjusted automatically when you program
the travel.
NOTE: If anything interferes with the door's upward travel it will stop. If anything interferes with the door's downward
travel, it will reverse.
UP (Open)
One-Piece Doors Only
When setting the UP travel for a one-piece door ensure that the door does not slant backwards when fully open (UP).
If the door is slanted backwards this will cause unnecessary bucking and/or jerking when the door is opening or
closing.
Programming Buttons
The programming buttons are located on the back panel of the garage door opener and are used to program the travel.
While programming, the UP and DOWN buttons can be used to move the door as needed.
