How to use a Harbor Freight 20lb sandblaster.

I just bought one. Even bought a 21 gallon tank compressor for it. Never thought of backing off the valves. Thanks

Where is the pressure gauge?

it didnt come with one but they are cheap less than 20$. I didnt use it i monitored the one on the compressor.
