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 exces-
sive 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 follow 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.
