Description: Leaks air from top Won't fire Driver won't return Leaks air from trigger Nails won't feed Doesn't sink nails deep enough Double fires. Nail guns use low pressure to pull the piston driver assembly back up to the top of the cylinder and this check valve helps it do that. Hex Sockhd Bolt M5x25 Nv45ab 10ps. The piston driver on my tool does not retract like it should when bump firing the tool. I thought it might be an easy fix so I took it a part now I'm not sure how to fix it and know I can't put the ribbon spring and needle roller assembly back without some help!
