Remove the locknut and backup washer completely from the “head-end”
of the fitting.
Screw the fitting into the threaded boss until the backup washer
comes into contact with the face of the boss.
Turn the fitting “head-end” counterclockwise to
the proper index (a maximum of one turn).
Hold the fitting “head-end” with a wrench and tighten
the locknut until the backup washer bottoms out. Be careful when
installing fittings. Do Not twist hoses when tightening.
