If the regulator won't shut off the air outlet, it likely means the regulator is damaged and needs replacement.
What to do if pressure drops on my Porter-Cable Air Compressor when using accessories?
Some pressure drop is normal when using accessories. However, if the pressure drop is excessive, adjust the regulator as instructed in the Operation section. Note that you should adjust the regulated pressure under flow conditions, meaning while the accessory is in use.
Why does my Porter-Cable C2550 make a knocking noise?
A knocking noise could be due to a possible defect in the safety valve (operate manually by pulling on the ring; replace if it still leaks), a defective check valve (contact a Trained Service Technician), loose compressor mounting screws (tighten them), or carbon build-up in the pump (have it checked by a Trained Service Technician).
