Oil flows from pump (17) to control manifold (15) . The control manifold includes the following components: an inverse shuttle valve, a check valve, a fan solenoid valve, a cut-in/cut-out valve, a priority valve, three pressure reducing valves, a shuttle valve and a pressure relief valve.Control manifold (15) controls the flow of oil from pump (17) to brake accumulators (7, 8) and piston motor (22) for the hydraulic fan.
