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
l
operation of safety reversal system.
After ANY adjustments are made, the safety reversal system MUST be tested.
l
Door MUST reverse on 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.
