Adjustment
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
system.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid
flat) on floor.
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.
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.
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.
