I own one, and have for many years. It has worked great until just now, it's having trouble firing. On the side it says something about unlocking the fuel cell (to purge it), then pumping the nailer 3 times, then resetting the switch. When I do that, it fires good one time, sometimes twice. But after that, it either just makes a weak noise, or it fires, but only sends the nail in a 1/2" or so. In the manual it talks about getting a replacement kit for the airfilter and the firing device. I went to the places that carry the brand, and (a) I do not see the kit, nor do they know about it, or (b)they don't carry a new one (at this point, I may as well consider getting a new one if this is going to be a real pita). I don't see it on the DeltaPorterCable website either. Have they stopped making the cordless 15gauge nailer (the one that uses the gas cylinders)? By the way, I tried other cylinders, that is not the problem. I have a ton of nails and cylinders, so I want to either get a new one or fix this one.

Has anyone else had this problem? What is the fix? Anyone know where I can get the kit? Anyone know where I can get a new one or even a refurbed one that is running like new?

Thanks, Ralph
