I have a Bostitch roofing gun that when I plug in the air hose and get ready to shoot the gun, it is like the air is not engaging the gun to fire. The pin behind the trigger doesn't seem to be coming out so when you put the gun down to fire there is no action.
Pop open your feeder and remove your coil of nails. Check to see if only one nail is in the barrel, if so close your feeder and dry fire the gun to shoot it out. These drivers are very strong and I have done this before on the job site. Or if that's to exciting pop the feeder and use a nail set to tap back the head of the stuck nail until you see the head where the feeder is then pull out with a needle nose. Check your feeder and driver tip. Guns don't just jam on there own, something else might be going on.
I loaned out my roof nailer and he tells me when he hooks up the air hose to it it blows continuous air out the nail discharge area. It still will nail but will continue to blow air out until the compressor is drained. Thanks. Steve
It will need a front o-ring Steve. Get the full kit and replace them all. Also,don't let the gun sit for long periods, drop 7-10 drops of gun oil in it and run it once a month so the seals don't dry out. Download a pdf to see how your gun is put together for the ring job.
I would suspect that your trigger valve has failed. The trigger valve is offer as a kit. The part number for the trigger valve kit is #TVA6 and is available from http://ereplacementparts.com.
Good luck with your repair!

TVA6 trigger or just the o-rings. You can get them on this site. A full o-ring kit for the gun should have the o-rings for the trigger. the trigger is simple to replace/rebuild and other o-rings,especially the driver will go as being used so it's good to have a full o-ring kit for less down time.

I have a bostitch n45b that will fire one nail but won't advance the nails. I have checked the coil of nails, cleaned things up a little. What might be causing this? I'm not exactly sure how the pawl works so don't have a clue what the problem might be.
