Have you tried to use a foot pump as a backup? Or maybe a try to blow into the bags and see if you can get it up? Just suggestions. Hell get a bicycle pump.
Aaron, just call air zenith. They will fix or replace it FAST. They had problems with the first run of compressors. One of the guys in my club just returned one, and had a new one back in a week. Problem solved.
i heard that they have problems with their check valve rusting out and blocking the passage to the tank, and a lot have crapped out that way. check into that.
