Hey Everyone,
I’m looking for some help/experience with brad nailers. I’ve had mine for a few years, always well oiled, and low maintenance. Just the other day, it was working fine. Went inside to have lunch, came back out, and it’s not firing. When the safety is activated and the trigger is pulled, normally the mail fires out. Now, you just hear air passing through somewhere closer to the trigger.
Any one have any ideas or suggestions? My guess is, a gasket somewhere has blown perhaps…but I’m not savvy in this department.
Any help would be fantastic.

First… UNHOOK THE AIRLINE… then check for a jammed nail.

No nail caught. I’ve fixed that issues a few times in the past.
Any other ideas?

This would be simple and I’m sure you’ve checked it already but are you sure that you have enough nails in the gun? The nail guns I used at my old job had a built in trigger safety that wouldn’t fire a nail unless there was at least (say 5 or so) nails left on the would leak air near the trigger like you are describing. I would every once in a while wonder why it stopped working then realized I was getting close to the end of the clip so I would just add another and it would fire perfectly from then on.

Most likely, the last nail you fired was the one that blew the gasket. Check to make sure the hammer isn’t stuck in the down position. If it is, pushing it back up might help. Your best bet is to look for a rebuild kit. They’re usually pretty inexpensive and pretty easy to install.

Right now I am not sure what a CH gun is but I have had this ecperience a couple of times. I have a Paslode framing nailer. It was working fine then sounded like it was leaking air. It was a gasket on the upper rim of the barrel or cylinder. Torn seal. It cost me about $7 at the local lumber yard to have all the O-rings and gaskets installed. Of course they treated me right because this is a town of 20,000 people and they want your business. The other times have been Porter Cable nailers. There is a white plastic or nylon part above the cylinder or barrel. The center will breaker out of this bumper. It is used to return the driver. IT seems to go out faster sitting that using.

Thanks everyone for the help, Grandpa seems to have had a similar issue. I’ll go that route and see what happens.

I’ve torn down too many nail guns to mention. Sounds like an o-ring has torn and is not returning the drive piston back to the top. There are also some rings in the trigger plunger/valve (proper term?). If your somewhat mechanically inclined don’t be afraid to tear it down. Do it methodically and even take photos and make notes. As your pulling it apart check everything carefully for tears, cracks, excessive wear, etc. Watch out for any springs that may want to jump out at you and pay attention to the orientation of everything to get it back together properly. If you find the culprit look up your model # online and get a part no and check some sites for prices or better yet order it from a local yard or supplier. You can usually save on the shipping that way.
I’ve torn some down and found nothing obvious, put it back together and it works. Better to be lucky than good looking I guess.
