I've been using dewalt tools exclusively for 15 years. I've fixed numerous drivers, sawzals, etc. I've learn 3 things over and over again. 1 cleaning & lubing are grossly under rated, 2 if one part goes the rest are not far behind & 3 it has never cost me more than $20 to $30 bucks more to have the repair place rebuild it than to fix it myself. And most times they give you a new bulk packaged tool as a rebuilt. My recommendation: have it rebuilt...enjoy the new tool.

problem solved.whoever had used the tool must have hit something hard because the drive pin had been pushed back just enough to stop it from cycling.
SOURCE: Dewalt 51488. Air leaks around trigger and won't fire nail.
Go to Dewaltservicenet.com and download a breakdown of the tool before starting. I would recoment changing all the O rings and make sure that you get a good grease to lube them first. Its not that hard.

First - the air pressure has to be high enough - check the regulator on the tank to make sure it is delivering in excess of 60-70 psi (which I am sure you have already done).
If you have dry fired these guns (i.e. shot them off with no nails in them while you were lubricating them maybe) the mechanism inside could be damaged. I had that happen to one of my nailers (same brand). That was when I learned not to dry fire them...
Since both of them are not working though I would be more inclined to look at the air supply first.

You have to take the front part of the case off, and you will see the problem. Either the drive belt is broken or the rubber band like springs have broken. Happened to both of mine after about 2 years of use. I ordered the parts through Dewalt and they have some nice diagrams showing the locations and how things go together. Not too hard to do
