Automatic Garage Door Opener OWNER INSTALLATION AND USER MANUAL

Adjustment # 1 Opening and Closing Force

This garage door opener is built with a safety system that allows the door to reverse in the close direction and stop in the

open direction. This must be adjusted so your opener does not use excessive force in the down direction or react to the

weight of the door during upward travel.

CLOSING FORCE ADJUSTMENT

To help determine that the closing door force is not excessive, grasp the door handle or bottom edge during downward

travel. The opener should REVERSE

to this force. NOTE: Do not stand under door during this test.

To adjust the closing force follow one of the two methods listed below.

Method A (manual)

1. Turn the FORCE ADJ. (see illustration) counter clockwise to decrease

force and repeat reversal test until door reacts properly.

Method B (computer assisted)

1. Operate the door to the fully open

position.

2. Turn the FORCE ADJ. (see illustration) counter clockwise to the minimal

force setting.

3. Press the PROGRAM SWITCH button two

times or the PROGRAM

button on the Wireless Wall Station (if included) until the LED turns on

solid (5 sec.). The STATUS LED and the overhead lamp will flash on

and off at a slow rate.

4. Operate the door to the fully closed

position.

5. Turn the FORCE ADJ. clockwise until the STATUS LED flickers or just

turns off.

6. Press the PROGRAM SWITCH once to confirm setting.

OPENING FORCE ADJUSTMENT

To determine that the opening force is not excessive, grasp the door handle or bottom edge during upward travel. If the

opener does not stop or is hard to hold, decrease the open force setting. The opener should STOP

without using

excessive force.

To change the opening force follow the procedure listed below.

1. Operate the door to the fully closed

position.

2. Press the PROGRAM SWITCH button three

times. The STATUS LED and the overhead lamp will flash on and

off. The blink rate which corresponds to the force setting will consist of 1 to 5 fast blinks followed with a long

pause between blink sets.

3. The first time an attempt is made to increase the force, the setting will begin at the lightest setting (1 blink).

4. To increase the force, press and release the door up/down button on any control (The STATUS LED will remain

lit during button press).

5. Continue to press and release the door button until the desired force setting is achieved.

6. Press the PROGRAM SWITCH once to confirm setting.
