Ok,

I just got a sweet used emag today. It came with a Maxflow. Now, I'm embarrassed, but all I've ever used is a Spyder with a Crossfire screw in. Simple as pie, right? Well, the Maxflow has knobs and screws and gauges and all kinds of crap. I thought it would have an on/off lever, but it only has a big knob that you can turn. When I turn that, air vents thru the gun. Also, can I just unscrew the thing, or will it blow up on me when I do it? It's a 3000, and its about a year and a half old. Can someone give me a remedial lesson on how this all works, and maybe a link to a "for dummies" on this tank?

I'll tell ya, this is a painful message to write and admit I know nothing, but I figure its better than hosing the tank, the gun, or myself. Much love to whoever can help me.
