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 qualied 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.
- After ANY adjustments, Safety Reverse Test MUST be performed to ensure the door reverses on
contact with a 1.5” high object (2x4 laid at).
