Always turn adjustment screw clockwise to adjust pressure. This will compensate for any internal friction
inside line relief valves that would oppose setting of bias spring. For example, if adjustment screw needs to
be turned counterclockwise by 1/2 turn to decrease pressure, turn adjustment screw counterclockwise by
one full turn. Then, turn adjustment screw clockwise by 1/2 turn.
Adjust line relief valves (30).
