ADJUSTMENT

INTRODUCTION

Your garage door opener is designed with electronic controls to make
setup and adjustments easy.
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.
CORRECT

The programming buttons are located on the left side panel of the
garage door opener and are used to program the travel.
DOWN (Close)
INCORRECT

PROGRAMMING BUTTONS
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.
