Brad nailer problem

[peter leyden]

I have a Porter Cable BN200 brad nailer that fails to return the driver to the ready position, hence does not pick up the next brad in line. I called PC and got basically no useful info. I did oil it, checked the cylinder walls for scoring removed the piston/driver assembly for anything amiss such as a bend in the driver, and the o-ring on the piston. Everything seems to check out OK. The nailer will drive the first brad, so what could keep it from returning?? Any help or suggestions will be gratefully accepted.
Bewitched, bothered and bewildered,

Did you clean and lightly oil the driver shaft where it slides in the head.
Sometimes it get dry and binds.
I have several of the BN125 and BN200 guns and have to do that occasionally.

Its either that or there is no air pushing the piston back up.

How do you get the nailer to "reset" to drive the first one? Could the row of brads be holding it down? I am unfimiliar with that particular nailer but I have seen where the strip of nails was protruding out after the first shot and causing the "hammer" to catch and not come all the way back up.

Make sure you have the correct nails. I have had trouble with discount nails that do not have the correct head size. The head of the nail is skinnier and causes a jam.
