Question about Dewalt D51850 Heavy Duty 20 Degree Full Round Head Framing Nailer
Orings /other parts tend to stick when nailer is new. Dewalt uses some vinyl orings that have been causing premature failure. Be sure to add a few drops of oil when used. Too much oil is not good. Wrong oil will cause orings to swell and cause problems such as yours. Your nailer's firing valve can be reset by rapping the nailer against rubber surface such as a thick rugger mat or coiled rubber air hose. Remove airline and nails, being carefull not to damage the head, rap had against rubber mat and retest gun. If it did not reset rap against nose of gun and test. If no joy, you will most likely need to remove head and manually move cylinder up/down and /or check vinyl orings for failure. Before you try to reset the gun, make sure that the safety is pushing the firing pin all the way in. Air removed, look under the trigger as you push down on safey, if it does go all the way in try bump-firing the gun (for test have nails removed). Hold in trigger and quicky /firmly strike gun against rubber pad. Good luck
