Compressor is designed to cycle on and off. Continuous 4.
running will cause damage to compressor and indicates
compressor is too small for the application. Check if
accessory SCFM is met by Compressor. If Compressor
doesn’t reach accessory SCFM, you need a larger
Compressor.
Follow all safety precautions whenever diagnosing or servicing the
compressor. Disconnect power supply before service.
