Auto Force Adjustment - Guardian 715BBU Owner's Manual

Auto Force Adjustment

To prevent SERIOUS INJURY or DEATH from improper Force Adjustment:
- DO NOT adjust force to compensate binding or sticking of the garage door. Call a qualified garage door
service person 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 flat).
