Hey wondering if anyone can tell me what is wrong with my nail gun. It is a Dewalt frame nailer model D51822. It was working fine. Then it went to just blowing air out the nozzle . I have took it a part and looked at all the o rings and wipers. They all look good. I took the trigger out and checked the trigger valve. It all looks good. Any ideas. I can get the trigger valve for $20 and a rebuild kit for $60 . I just don’t want to buy 1 part and end up needing another. By ideas throwing it away and buying a Bosch isn’t the idea I’m looking for. I already thought of that. Thanks in advance.

Do you regularly oil it?

It did lay for about a year without being used or oiled though. When I use it, I oil it though.

I would guess that you have a bad o-ring or a diaphragm of some sort. I had a similar problem once with my Porter Cable framing nailer. The rebuild kit fixed it. Since then, I make sure that I shoot a few nails through it every couple of months if I haven’t been using it.

Good luck.

I had the same problem with 2 Craftsman nail guns. I solved it with the solution you don’t like. They went out with the recycle trash and I replaced them with Bosch nail guns. Those guns must be about 3-4 years old now, not used sometimes for months but they have never failed.

Also I am starting to think DeWalt isn’t such a great tool line. I’ve had trouble with both my cordless drills, my 12 !/2” planer and an orbital sander. Their customer service sucks and their warranty is just a piece of paper. They seem to be rapidly sinking to the level of Black & Decker and Craftsman.

My grand dad used to say ” it only costs a nickel more to go first class. In his day a nickel bought something but it still holds true today…spend a little more on a better tool and in the long run, it will cost less as it will last longer.
