My air compressor leaks

My air compressor will build up to 125psi then leak down to 80psi.When it leaks down to 80psi it comes back on.

Where is it leaking from? If the air is coming out of the unloader valve at the pressure switch, you need to see this page on leaking pressure switches.

If not the pressure switch, then stop the leak wherever it is.
