I have a sears 2HP Compressor that my brother inlaw gave me [img]smile.gif[/img] I just got a reconditioned Brad nailer. it says the PSI is 70PSI minimum and 120PSI maximum. Do you guys know how to raise and lower the PSI on the compressor. It's got two gauges on it. It also has a knob that you can turn. If you turn the knob clockwise it seems to hold the pressure longer. If you turn it counter clockwise it lets the air out faster (I hope I'm explaining it properly). I thought that this was to regulate the pressure but even when I turn it to get less pressure it still goes back up to 150PSI on both gauges. The high is set at 150PSI and it kicks back on at arountd 110PSI. So how do I lower the pressure to 120PSI?
