5.18.3 Load Sensing
For the load sensing configuration, a valve
is additionally installed on the hydraulic
control valve. A knurled screw holds the
valve closed and a "constant pressure sys-
tem" is present.
If the valve with the knurled screw is
opened, the individual hydraulic functions
can be operated without load sensing.
