This is a genuine OEM approved replacement part designed for use with Rolair compressors. The pressure switch is a mechanism which communicates to your compressor when to stop and when to start building up pressure. There are multiple reasons a pressure switch could be leaking air. To complete this repair you would need: wrench set, nut driver set and a thread-sealing tape. • Shut off the electricity and drain the air tank • Remove the tank pressure gauge • Remove the pressure switch tube • Remove the pressure regulator assembly • Disconnect the wires • Remove the safety valve • Install the new pressure switch • Reinstall the safety valve • Connect the wires • Reinstall the pressure switch tube • Screw the pressure gauge onto the new pressure switch and tighten the gauge firmly • Test the air compressor
