Dewalt framing nailer leaks air
 
I've got the: Dewalt Heavy - Duty 31 Clipped Head Framing Nailer - D51822

As soon as I hook up the hose to it there is a leak some where. It's faint but makes my compressor kick on immediately. I can't really locate where the leak is coming from either. I know it's not the hose area....almost sounds like it's the back of the cylinder.

It's brand new but if it's a simple o ring or something I'll just fix it rather than having it sent out.

It still has enough pressure to work...but it kills the compressor after about 10 shots and I've got to let it catch up.

Thoughts?

if it's brand new, take it back and exchange it. if problem persists, it's likely the hose.

I got it off the net..so it would cost me $20+ to ship the stupid thing. That's why I don't mind buying a few simple parts for it.

*ouch* well, then i'd be inclined to start taking it apart to find the leak, myself....
hard to believe a new DeWalt tool would leak air though.... are you using snap on/off couplers?

Ayuh,... If You can't find the leak, how are We supposed to Help,..??

Hook it up,+ use your hand, fingers, whatever to find the leak...
If that don't work,...
Use a spraybottle of soapy water to find it...

Tighten all the screws. It's probably a housing gasket that's not snugged down enough. It happens.

I was looking for suggestions of where a leak might be common in framing nailers or if someone was familiar with this model.

Maybe an idea of where I should be looking? Some common problems? There's an idea...

Sorry to ask...

Awesome, thanks, I'll try that out tonight.

Try this: hook up your compressor, let it run until it stops, watch it/time it to see how long it takes until it starts again. Hook up one air hose, let the compressor run until it stops this time, watch it/time it again. IF it seems to leak down faster with the hose attached, then one of the quick-connect fittings will be leaking, time for the soapy water trick. Even if you find a small leak, attach your nail gun, lay it down and do the timing thing all over again. IF you find a significant loss of air with the gun attached, you have a problem with the gun, soapy water trick again. IF the couplers are leaking, the best solution may be to buy new/better couplers. Trust me, they make cheap/leaky ones and nicer/non-leak ones--I know. IF it's the gun, then as suggested check all of the screws and even where the air fitting screws into it. Hold it close to your ear and listen--keep your fingers OFF of the trigger though :). Good Luck, David
