Bank valve (1) Line relief valve for the ripper control valve (2) Optional ripper control valve (3) Angle control valve (4) Lift control valve (5) Tilt control valve (6) Main relief valve (7) Outlet port (8) Optional power beyond manifold (9) Inlet port (10) ManifoldThe work tool system is an open centered, manually controlled system. There are separate systems for each group of cylinders on the machine.If the machine is equipped with an optional ripper, line relief valve (1) for the head end circuit will be part of ripper control valve (2). Main relief valve (6) is mounted in manifold (10) in order to maintain hydraulic pressure for the work tool system. The following circuits use the main relief valve for circuit protection: lift circuit, tilt circuit, angle circuit and rod end circuit for the ripper circuitAll of the control valves contain load check valves. Lift control valve (4) and ripper control valve (2) contain makeup valves. The makeup valve for the lift circuit is in the head end circuit. The makeup valve for the ripper circuit is in the rod end circuit.When the control levers are placed in the HOLD position, the control spools in the valves block the flow of oil to the cylinders and from the cylinders. Centering springs in the control valves keep the spools in the HOLD position.Movement of the blade is possible when the engine is stopped. The weight of the blade allows cylinder oil to flow and the blade lowers to the ground.
