I have a SIP 50L 3HP compressor and when first run to fill up from empty the pressure switch does not stop the compressor and it blows the pressure relief valve. I then stop it manually by pressing the red button down. Then if I pull it back up it does start to behave normally and stop once a topup is complete.
Is there anything I can look at or do to sort this or do I need a new pressure switch block? It did used to work OK.
