The nailer was leaking air and would not drive a nail.
I had a o-ring seal kit on the shelf. I found the old seal stuck and gunked up. I had to use scotch-brite to clean that surface before installing the new o-rings
For some reason I did not have a piston stop and I don\'t know how this nailer ever worked without it? After cleaning everything up, lubricating and installing all the part
... Read mores, the nailer worked fine.
Thanks
