I have a similar issue with my T50m stapler. To remove the staples unscrew the locking nut near where you load the staples and remove the tapppered bolt. The track will lift out and the staples can be easily removed. Why this is happening is unknown to me also. I purchased a new gun.

I just rebuilt my Senco SN4 nail gun because it had a constant air leak coming out of the discharge vent on the top of the gun. I replaced all of the o-rings that came with the kit except there is a split gland seal in the mechanism above the piston. Is this seal suppose to be split, and should one have come with the kit? I'm not sure if this is the problem, but the leak has not changed at all.
