Air compressor regulator

[nabu92]

I have an 8 gallon air compressor and it has a valve right before the hose connection that has + and - printed on it. I believe this is the pressure regulator. I was wondering if I turn this valve right (+), will it allow me to pump up my gun to higher pressures? My gauge isn't working atm so I cant try it myself. Thanks for your time.

Here is how my compressor looks like http://www.harborfreight.com/cpi/photos ... /90385.gif

Yes, it is a reg. you should be fine to turn it up all the way because i remember that compressor being like 120 psi witch is perfect for spudding

some times the reg. knob has to be pulled out. it moves about1/8th inch
or so ,it is some kind of lock
