I have never done any work on nailguns. Never installed a rebuild kit or nothing. So I am hopeing someone on here could advise me of what I am looking at time and expense wise.
Symptom.
I plug my airhose onto the gun and hear a little bit of air leaking. When I push the tip to shoot a nail, no nail comes out, but there is a whoosh of air from the little odd shaped hole centered above the handle.
I am thinking trigger valve?

I would just get a complete rebuild kit and go through the gun all at once. Do you know anybody who works for a dentist?? Get a few basic old dental tools to grab the O-rings and remove them.
Most of the time it's something in the piston area that has broken. I have replaced a lot of top cylinder seals, but it could be almost anything if the gun was dirty.
It's nice to have a tank type parts washer. Take the gun apart and clean one piece at a time and replace the o-ring or part on that piece only. If you tear everything apart at once, you will never figure out what goes where. A lot of those o-rings look alike and in some kits you have more than you need, so be very careful to compare the parts (old to new.)
Lube the parts with gun oil as you reassemble. Be sure to soak and blow out the main body of the gun.
It's not hard and you can easily do it in an evening. Seems to me it usually costs me about $20 or so for a complete rebuild kit.
Ok Thanks.Webby
I could be the piston that is broke. Not a hard fix, when you have the gun disassembled for replacing o rings.
What's frame pro? Senco?
I have an hitachi NR83 and have done a few minor things here and there on it. They are very easy to fix, just takes a little time and patience. Check on the manufacturers website and they'll probably have a parts schismatic, that is very helpful. Also, I have a good parts place for tools around me, they fix them too but will sell you the parts if you want to save the labor charge. I will usually talk to the parts guy that fixes them and describe the issue and he always knows what the problem is right away.
Also any time I'm not sure of something I take digital pictures as I go so I can figure out the issues if I get lost on putting it back together.
Good ideas everyone Yes it is a Senco.
Update...
I am sure it is not the driver. It is funny because it will shoot a few, then as soon as I unplug it from the hose and reconnect it just spurts air from the top. It shoots fine when it gets going.
When it gets going just don't stop I guess.

See, you answered your own question!!
We ahd a senco once that had a very funny habbit of doing very close to what your is doing.
I took it to the shop and they said it was fine.
Did that about three times.
Not sure how we discovered that if safety was in and trigger was held while attaching hose that it woudl "pop" and work fine all day. It never fired a nail with the "pop"
We got to where we would would just say, "hey, u didnt prime that gun"
We were sitting at lunch one day and heard the "pop" then a sound of a nail bouncing around walls. Turns out gun fell off something and when it hit something got jarred around, but that time it fired a nail. We retired that gun.
I recently tried giving it to the senco guy after showing him what it did. He told me to keep it as a reminder of how dumb was for so long when all I needed was an O ring. Lucky I didnt kill someone.

Was there ever any doubt?
No taking coffee breaks ... just keep nailing until the project is done. ;) so where is the problem here?? ;)
Im with you. I plugged that thing in last night and it decided to work. I nailed off all the floor I could get to because I new not to disconnect.
When I was done I unplugged it, and just for fun plugged it back in and nothing. I just smiled 'cause I got the job done and beat it at it's game.
Once I get it to work it doesn't stop, and shoots great. When I unplug it that is it, it is shot, until it sits for a day or so.

I don't think freezing is a problem it is stored in a garage, and I am working indoors now.
Oh, beleive me I have whacked that thing, dropped it on the deck, "tapped" it with a hammer etc.
Nothing helps. Don't get me wrong I take excellent care of my tools I don't beat on 'em unless they beat on me first.Webby
I would be you $$, it's the big top cylinder seal. If you remove the top cap, you will probably see a big crack in the cylinder seal, or a piece missing.
Get brave and remove 4 screws. If that is it, then you don't really have to tear it down any farther unless you want to replace the o-rings.
Ok, thanks for the advice.
I am kind of in the middle of the hardwood now and don't really use the framer everyday. I will dig into it after I finish the flooring.
I have never put down 2-1/4 before. Just 3 to 4 inch. I worked for about five hours today and only laid three linear feet. Just me no helper to rack out or make end cuts so it is pretty slow.Webby
Very tedious work!!! It's bad enough if you have help.
You almost need a pep talk when doing flooring like that. I always have the same situation, you work like crazy and at the end of the day you cannot understand how more isn't finished.
Yeah, I had a buddy help me today. We got six linear fet and were happy with that in about five hours. We were not working hard but it was fun. He had never done hardwood before so I was showing him things and we managed to get alot done.
I am no pro at it either, but have done some at work.
Anyways I have got the time things are slow now.

Go figure, huh? Ain't technology great? I was kind of kidding ... but whatever works, right? I have a FramePro, too. Used it to frame my entire house ... generally worked well all the time. The occasional misfire ... er jam, but no issues otherwise. Switched between the bounce fire and the other (spot fire) triggers. Both were great. I just kept it oiled daily like you're supposed to.
It's junk! Just go ahead and send it to me :) actually i have one that did that and oiling it would work for quite some time then you had to oil it again ;) but it will need O rings soon.
Well, I dont use it every day and I did buy it used off a buddy. I am kind of just putting up with it for now because money is tight. I was using it to renail subfloor before hardwwood install. Guess I'll just screw it.
It is hard to type with bandaids on two fingers!

pull it apart and check it out first, you might find something obvious. My hitachi NR83 would shot a nail but the driver would not retract after the shot. I could push it back up then it would be fine for another shot, etc. Called my tool parts place and he said it was probably a rubber band that fits on the piston. Opened it up and it was right there broken. Replaced that for a few dollars and it works perfectly.If the gun has never been abused, and I mean abused, then just do a rebuild. The guns are basic and really do last a long time. My hitachi is probably 15 years old and with some o ring replacements from time to time it will last forever.
Okay thanks.Webby
The 601 I had was eligible for a free repair kit years ago for a similar problem.
My 601 often behaves like that when I first plug it in and it's cold. A couple of times I found it could be fixed by whacking it across the side of the head with a 2 x 4. (My preferred solution to a lot of problems) What was in the kit?
The local repair place thought it might be icing and told me to dismantle the head and grease it lightly with lubriplate. I haven't done anything about it yet.
