The air compressor relief valve setting pressure to reduced by unwinding the compression nut by one turn keeping it in the manual position. Then the compressor to be started and the compressor will blow at a pressure below the previously setting pressure. Or, Increase the set value of the high pressure cut out value from pressure switch above the pressure relief valve set pressure and start the compressor, after reaching the set value of the relief valve it will blow.
