Craftman air compressor pressure issue

It is a 20 gal 2hp it only has 100 psi how can i get it up to 120 psi?

Bill says...

Are you saying that the high pressure cut out is 100 PSI, and then the compressor stops?

Was this the setting that came with the compressor when you obtained it?

That being the case, the 100 PSI level is factory set, and your compressor is designed to have a 100 PSI maximum pressure. Trying to get that higher may reduce the life of your compressor.

If you need a compressor that delivers substantially higher pressure than the 100 PSI that you are getting from this one, my best advice is to get a properly sized compressor.
