I’m having trouble with my 15 ga. Bostitch angled finishing nailer.
Since last night, i’ve had variable results when i press down the nosepiece: sometimes it fires on a trigger pull, but sometimes not. I can pull the nosepiece off and press it again and get it to fire eventually. IOW, i’m not trying to bump-fire, which it doesn’t do. I’m running it off a little Senco compressor, which is easily keeping up with my speed. <g>
It seems to be getting more ornery as the day progresses, and i haven’t dropped or mistreated it. It’s probably only had a couple thousand nails through it in its whole life.
Any ideas for a fix, framers and finishers? I’ve never had a gun act like this before and i can’t find anything on the Net about it.

oil and air preassure OK?
Spring behind the trigger OK?
Spring on the trigger is intact. I use a couple drops of oil before starting each day, and the pressure reads 125 psi onthe regulator and it's setting the nails just fine. I was loathe to oil anything connected to the nosepiece for fear of collecting dust. It's all moving easily, though, just like normal. There isn't any difference in the feel between when it fires or not...except it doesn't. No catches or anything. I'm doing baseboard instead of working overhead now...seems to not be having as much problem angled down as up. Hmmm...looks like a project for after i get the room done...hopefully it'll take me through this phase.
Try cleaning the coil that presses the nails forward- sawdust or gunk reduces the pressure sometimes. Air or w/d.
Whack it good and stoutly with a hammer handle or short billet, right on the nose. Really, a few good thwaps like slamming the nose into a workpiece.
You have something hung up in that saftey or the drive depth setting doo-hicky.
I don't recall if that gun will dry fire or not ( I had two, but it was a long time ago) if not it may be the nail feed spring, not getting the nails up to the driver blade. and you reapeatedll trying to fire, may have advanced them just enough.

I have that same gun. Mine acted up like that when I went to use it after it had sat idle for a long while. I picked up an o-ring kit for it and took it apart. The kit comes with directions and it was not difficult. Fired fine after a cleanout and new seals/o-rings. Don't over oil.
I think that's the nail hit on the head! I haven't used this gun in at least a couple years. I'll pick up the kit tomorrow when i go to civilization. Thanks to all, and special thanks to you, Mike! God, i love this place...even on a holiday...
I have had the same problems I check to make sure the nail's are feeding properly. Then it's the oil, spray the nail guide with brake cleaner. I haven't had the problem since adding a oil water seperater the small one to the fitting end of the compresser. fixed my problem's so far.
Nails seem to be feeding fine, and it doesn't dry-fire, either, but i'll try the brake cleaner spray to the guides. Thanks!
splintergroupie,
Try cleaning the area around the nose with WD40. don't spray any into the air chamber but it's perfectly OK to clean off the nose and nail slide with WD40
I found that some nail strips are slightly bent and spraying the slide with WD 40 will allow the nails to slide along the rail easily..
I first sprayed brake cleaner, then the WD40, and blew out the particles around the nose. The nails slide more easily now, but it's still not firing properly. About every third or fourth nail, i have to lift it up and set it down again one or two times. I got through my project today, but now i'm going to get and install the kit Mike585 talked about. Thanks anyway!
