Lift arm positioner valve location | |
Lift arm positioner valve (4) is located on the loader frame forward of the articulation. When magnetic switch (2) closes, power is supplied to lift arm positioner valve (4). The lift arm positioner valve closes.
Lift arm positioner valve (4) controls the flow of pilot oil to and from the main control valve. When the lift arm positioner valve closes, pilot oil from the main control valve is sent to the hydraulic tank through an orifice. The lift spool in the main control valve gradually returns to the CENTER position. The lift arms will come to a controlled stop.
The height at which the lift arms come to rest can be varied by adjusting the position of magnetic switch (2). Moving the magnetic switch upwards will raise the lift arm height. Moving the magnetic switch downwards will lower the lift arm height.
