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

I disassembled the gun carefully to see how each part works & to reassemble gun,
After cleaning gun, I put on the new parts & it nailed perfect. This gun is about 30 years
old & thank you for still having the parts!

Cylinder seal cracked, (it was about 20 years old but saw occasional use)
1 - Loosen the 4 Allen head screws from nailer head. It is slightly spring loaded so if your gasket is holding the head you may want to break the seal before completely removing the 4 allen head screws.
2 - Remove the old cylinder seal. Clean out any debris.
3 - Clean the nailer body and head mating surfaces for the new gaske

4 - Put a few drops on oil on the new seal to help it snap into place without damage.
5 - Re-install the head with the new gasket. Tighten the allen screws using a typical \"star\" pattern.
