ADJUSTMENT

Introduction

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)

DOWN (Close)

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.

Without a properly installed safety reversal system, persons

(particularly small children) could be SERIOUSLY INJURED or

KILLED by a closing garage door.

l Incorrect adjustment of garage door travel limits will interfere

with proper operation of safety reversal system.

l 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.
