Auto Force Adjustment
WARNING
To prevent possible SERIOUS INJURY or DEATH:
- DO NOT adjust force to compensate binding or sticking of the garage door. Call a qualified garage
door service technician to make necessary adjustments in case of binding.
- DO NOT increase force beyond minimum force required for closing the door. Too much force will
cause improper operation of safety reversal mechanism.
- If either the Force or Travel limit adjustment is made, the other adjustment may also needed.
- After ANY adjustments, Safety Reverse Test MUST be performed to ensure the door reverses on
contact with a 1.5” high object (2x4 laid flat).
For safe operation, the force setting should
always be set at the MINIMUM FORCE
required to run the door. Setting Force
Setting Close Force
1. If the door completes a full close cycle without reversing,
decrease (-) the Close Force by 1 level at a time until the door
reverses. If the door reverses during closing, increase (+) Close
Force by 1 increment. The Close Force is now properly adjusted.
2. During the ”door-close” cycle, the Opener will reverse if
the force required to close the door is exceeded.
Setting Open Force
1. If the door completes a full open cycle without stopping,
decrease (-) the amount of force by 1 level until the door
stops during the opening. Once the door stops during opening,
increase (+) Open Force by 1 increment. The Close Force is now
properly adjusted.
2. During the “door-open” cycle the Opener will stop if the
force required to open the door is exceeded.
Adjusting Force
1. Force Adjustment controls are located on the rear panel of the
Opener. The force adjustments regulate the amount of force
required to open or close the door.
2. Force Adjustment is applied only to compensate for the minor
resistance caused by weather or other means.
• Note: Force is preset at level 6 for both Open and Close
adjustments. The size and operating conditions of the garage
door will determine the correct level of Force/Sensitivity.
Weather conditions may also affect the operation of the door
requiring further adjustments as needed.
• Note: If the close force is set too light the Opener will reverse
the door during closing. If the open force is set too light the
Opener will stop the door during opening.
• REGULARLY CHECK and TEST the Opener according to the
safet label to ENSURE SAFE OPERATION.
• Never adjust the force setting by more than 1 level (1 press)
at a time.
