Trigger valve was leaking on frame nailer, also slow leak in main cylinder
Drive retaining pins from trigger and trigger valve. Remove trigger valve and replace. Be sure to grease new valve before installing. Replace retainer pins and trigger. Then for the main cylinder, remove the head and pull cylinder assembly out. Inspect for damage, replace any 0 rings that need it or lubricate them. Reassemble the cylinder and insert back into gun. Grease head gasket and replace. Pressure test and fire the gun. Make sure nails are advancing and no air leaks. Good to go!!
