Sounds like the plunger has broken, four allen head screws on top of gun remove and pay attention to each part and how it comes out. not hard to replace if you want to attempt it. just lay the parts out in the order removed and clean and oil then put back in reverse order.

My ridgid r213bna nail gun won't fire a nail, but has good pressure & no jam...


If a gun is firing and nails are not being driven into the work it's because of one of two problems. The nails aren't feeding fully under the driver or the driver isn't fully retracting each time the gun is activated. Is looks like you've eliminated a feed problem so you are going to have to take the gun apart to find out why air is not being held in the bottom of the head long enough to push the driver back up the cylinder. Go to www.ereplacementparts.com and bring up your model so you can follow along. Remove the four screws holding the head cap on. The things that can cause your problem are: the piston seal & o-rnig are damaged, the cylinder is badly scored, the o-ring & cylinder ring on the bottom half ot the cylinder are damaged or out of place, or the driver guide under the bumper is broke or missing. If it turns out internal parts are damaged or missing, I highly recommend the overhaul kit to replace all the 'soft' parts inside the gun as long as you have it apart.

I have a N59 FN air is leaking from the bottom of gun I put ne trigger and O rings still leaking now what.


Air leaking from the bottom of the gun (path of driver) indicates that cylinder seal orings are leaking (if without nails in gun the driver is slowly pushed down the cylinder when air is connected then cylinder seal is leaking ). Cylinder seal snaps on the top of the cylinder and should fit snug and have no cracks. Easy fix for cylinder ring. Remove head and pull out cylinder. Then remove the cylinder ring (part #n50015). Examine ring for cracks and replace as needed. Examine body of gun where spacer oring makes contact and sand fine scratches. Replace orings as needed. If air is leaking between body of the gun and nose casting, replace gaskets. Good luck.

Air leaks thru exaust on Hitachi NV 83 nail gun I have replaced exaust valve and several o rings to no avail.


Examine exhaust tube under valve for cracks and make sure that the tube seals correctly against body of the gun with rubber gasket. If tube is ok and has rubber gasket in place, check for correct cylinder movement. Press down cylinder with thumbs, the cylinder should return. If it stays down, pull it back up. If it is very hard to pull up, cylinder orings too tight or body of gun is warped. If it comes up with light to firm pull, go ahead and reinstall the head and test. If air leaks, try bumping the head of the gun (with air connected) against firm rubber to reset the cylinder against headvalve. If it still leaks, suspect that the cylinder is not moving up against the headvalve due to tight fit. Remove the cylinder and sand surfaces where orings contact to remove fine scratches with 400 grit paper. Also stretch the spring below the cylinder a bit to exert more pressue. Lube the cylinder with silicone paste lube. If you suspect warped body, remove all the orings from middle section the gun and insert the cylinder into body looking for out of round (with no orings the cylinder should just slide in to body of gun easily). Good luck

Just replaced o rings and piston bumper, but gun still leaks air (out of nozzle) and wont fire at all


Air leaking thru nozzle (where nail exits ) can be caused by two issues. Air leaking past valve rubber at top of cylinder where headvalve seals when under pressure. If leaking at valve rubber seal the piston will usually be pushed down if there are no nails in gun. If the driver stays up while leaking then problem is at cylinder plate. This plate has two orings that seal air pressure. On seals against the body of gun and the other seals against cylinder. Leaks can occur if body of gun is worn, warped or has scratches where oring makes contact. Also look closely at the plate for crackes. Replace parts as needed. Good luck

Fireing pin moves very slow, it seems to have no power. It comes out slow, I have to push it back inside the gun. It was leaking out the back so I adjusted the cyclinder and now the piston moves too slow...


When you trip the safety and fire the gun, the cylinder drops down into body of gun allowing a rush of air to push piston down with force. If the cylinder fits too tightly in body, it will not open enough to allow full air pressure into cylinder. Remove head and check that the cylinder moves rather easily down then back up (it should travel about 1/4 inch). If is difficult to move the cylinder then remove it and replace all the orings that contact its surface. Also make sure that the outer part of the cylinder is smooth where orings contact. If there are fine scratches, remove them with 400 grit sandpaper. Lube cylinder/orings with silicone paste lube. While cylinder is removed check that lower bumper is in good shape with no missing pieces. For best performance, also replace the three orings on the feed piston. Piston /driver should move down cylinder with only slight pressure yet it should not drop down the cylinder under its own weight. Good luck

On my Hasselblad 501 CM, I have never encountered this problem. As expensive as these cameras are, and delicate, I wouldn't chance it. I would contact the Hasselbad company and ask them to fix it for you.

Good luck on this.

Air leaks from the bottom of nailers are due to leaking oring /s that seal cylinder to body of gun and/or leaking thru seal at top of cylinder where headvalve seats. Remove head and examine sealing surfaces of headvalve and top of cylinder. Must be smooth, then pull out cylinder and check oring/s that contact body of gun. Remove any fine scratches on inner body with fine paper (400 grit). Lube with silicone paste. Good Luck!

Paslode 900420 piece fell out


Be sure to remove the metal nose piece that covers the lockout bar when assembled. It may be stuck to the other half of the gun. Replace the bar and the spring and put the metal nose piece in its position over the lockout bar. At this point the metal nose piece will be on the opposite side. This will allow you to replace the 2 halves carefully so as not to loose the spring.
