Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the safety reversing sensors are completely installed.

Limit adjustment settings regulate the points at which the door wilt stopwhen moving up or down.

The door will stop i6the up direction if anything interferes with door travel. The door will reverse in the down direction if anything interferes with the door travel (including binding or unbalanced doors).

To operate the opener, press the Door Control push button. Run the opener through a complete tra,_el cycle.

•Does the door open and close completely?

Does the door stay closed and not reverse unintentionally when fully closed?

f your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails (See page 30).

Adjustment procedures are outlined below. Run the opener through a complete travel cycle after each adjustment.

Repeated operation of the opener during adjustment )rocedures may cause the motor to overheat and shut off. Simp/y wait 15 minutes and try again.

Read the procedures carefully before continuing on to Adjustment Step 2. Use a screwdriver to make limit adjustments.

How and When to Adjust the Limits

•If the door does not open completely but opens at least five feet:

Increase up travel. Turn the UP limit adjustment screw clockwise. One turn equals 2" of travel.

NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4" between the trolley and the bolt.

•If door does not open at least 5 feet:

Adjust the UP (open) force as explained in Adjustment Step 2.

•If the door does not close completely:

Increase down travel. Turn the DOWN limit adjustment screw counterclockwise. One turn equals 2" of travel.

If door still won'tclose completely and the trolley bumps into the pulley bracket (see page 4 or 5), try lengthening the door arm. (see page 26).

If you have adjusted the door arm to the maximum length and the door still will not close completely, lower the header bracket. See Installation Step 1, pages 12 and 13.

•If the opener reverses In fully closed position: Decrease down travel. Turn the DOWN limit

adjustment screw clockwise. One turn equals 2" of travel.

•If the door reverses when closing and

there is no visible Interference to travel cycle:

If the opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or obstructed. See Troubleshooting, page 23.

Test the door for binding: Pull the emergency release handle. Manually open and close the door. If the door is binding, call for garage door service. If the door is not binding or unbalanced, adjust the DOWN (close) force. See Adjustment Step 2.
