(5) Swing drive (6) Ball valve (7) Front of machine (E) One pump flow (F) Two pump flowBall valve (6) controls the one pump flow or two pump flow. This provides additional pump oil to the boom cylinders. With the lever in position (E) , the one pump flow is operational. When the lever is in position (F) , the two pump flow is operational. Ball valve (6) is located to the left of swing drive (5) .Types of Ball Valves
