(7) Auxiliary control (8) Switch (9) Switch (10) Joystick The pilot lines connect the valve sections to the joystick for the loader. Joystick (10) controls the lift circuit, the lowering operation, and the float detent for the bucket. The loader control also controls the bucket dump and bucket tilt function. If the machine is equipped with the auxiliary circuit, auxiliary control (7) is connected to the auxiliary control valve.The loader lever also contains the trigger for the transmission neutralizer. When the trigger is squeezed, the trigger disengages the transmission. Disengaging the transmission allows more power to be available to the hydraulic system.The joystick for the loader also contains the switch (8) and the switch (9) for the all wheel steer (if equipped). Signal Network System
Illustration 3 g01369305
The signal network between the loader valve and the backhoe valve is separated by a check valve. The check valve is located in the inlet manifold of the loader valve. The maximum signal pressure for the loader is controlled by the signal relief valve in the inlet manifold of the loader valve. The maximum signal pressure for the backhoe is controlled by the signal relief valve in the outlet manifold of the backhoe.
