They haven't made it easy though.

I have the DX, and I only use it for Presta valves. With mine, the lever is down to insert it onto the valve, and up for inflation. On yours, the head probably unscrews, and the black rubbery piece the grabs the (Schraeder) valve might be inserted wrong-side out. It's easy to remove this piece and put it back in the other way. This might be the problem. Be careful to do this over a clear area, as the pin in the pump might fall out. If it does, no big deal, just put it back in. Probably stating the obvious, but make sure the pump is seated on the valve stem all the way. Good luck!

I think I know your problem: The valve at the bottom of the pump which controls the in-out flow of air can get clogged largely with residue from the gasget as it wears. My suggestion is to take the pump back to the shop where you purchased it as Topeak usually honors its lifetime warantee.

They don't list that model anymore but you could look around here and maybe the instructions for a different one will work for you.
