Hello guys I have a problem that needs a solution yesterday. I have a DeWalt nail gun that just today start acting weird. First it would shoot nails into the wood normally and at time it would fire and no nails would come out. Now this afternoon when I pull the trigger it won't even fire, every time I squeeze the trigger you can hear air escaping . ONLY when I squeeze the trigger does air escape from around the trigger area. I thought I would post my problem here because I believe some one may have had a similar experience and may be able to help me. Thanks guys. I will check back ASAP.

Have you been periodically oiling the gun? Sounds like your piston seals are gone.
