I have a Bostitch nail gun (pneumatic) and it has been working fine all day until about 30 minutes ago.
I went to nail in a piece of molding, and when I pulled the trigger I heard air feed into nozzle, but not the normal noise I hear when a nail is actually driven into the wood.
I first checked to make sure I wasn't out of nails and I had a full stack of them.
I then disconnected the gun from the air supply line and took the nozzle off. This is what I found:
Every now and again I get a misfire when it tries to fire two nails at the same time. In these situations, I disassemble the nozzle like I did here and get the nails out. When I took the nozzle apart this time, I noticed that the "hammer" (the thing metal piece that drives the nails in) was not in its correct position.
Usually, the hammer is fully extended, taking up the entire length of the nozzle that you see above. However, in the photo, you see that the hammer is stuck in the "ready to fire" position and will not come out.
I'm not sure if that's the problem (that the hammer is stuck inside the gun), or if something else is going on, but I've spent almost an hour looking at this and am at wit's end.
Any gear gurus out there see what the problem is? Is there a set of things I should be looking for to render a diagnosis?
