Hi,
I just also bought this compressor, and it looks very nice, except the manual sucks big-time.
The power switch has two 'On' settings like this: I O II, where O is off. Can anyone tell me the difference between the two On settings? I turned it on the first On setting 'I' and it ran for about 1min and shut off, and automatically restarted again after I pulled the ring to let out air. The second On setting 'II' ran for several minutes and never shut off.
I just got it today, and don't have my airbrush yet (it's in the mail), and they sent me the wrong air hose. So, I can't really test it yet, but I was trying to figure it out a little bit.
