This thing has less than 20 hours and looks brand new (passed
warranty). I contacted Stanley/Bostitch and replaced just about every
seal this thing has, including the trigger valve. Using 110psi, I
press the trigger and air comes out of the trigger but the gun does
not fire (cycle). I'm not about to send this to be repaired since I've
seen these refurbished for around $50. Any ideas? When I put it away
last July, it worked.

I have a similar problem. Will bot fire nail. Seemed like he trigger wasn't working properly. Took out the 'roll pins' and found that the valve that controls the depth of the nail was nor allowing the safety on the trigger to engage, when pulled. cleaned and was able to get one nail to set and the problem returned. Looks like the adjustment for the pressure/switch release is faulty.
Haven't contacted Bostitch. Of course I didn't keep my receipt!!
