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
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.
To prevent damage to vehicles, be sure fully open door provides adequate clearance.

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 left side 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.
