5.9.1.1 Load-sensing hydraulic system
Connect the hydraulic system only after it has been
depressurized.
Turn the tractor engine off before connecting the hydraulic
system.
Always connect the load-sensing control line when connecting
the hydraulic connector "Flow line" directly to the hydraulic pump
of the tractor.
The electro-hydraulic control block of the machine is directly connected with the hydraulic pump of the
tractor via the load-sensing control line. The current machine demand for hydraulic oil determines the
pressure and the delivery rate of the tractor's hydraulic pump.

Connect load-sensing control line
1. Screw the load-sensing control line (2) into the connecting aperture (Fig. 32/2.1) of the electro-
hydraulic control block.
2. Lock the pressure regulator in the electro-hydraulic control block. For this purpose
2.1 screw the load-sensing screw (Fig. 32/2.7) in as far as it will go.
3. Connect the load-sensing control line (2) to the load-sensing connector of the tractor.
4. Connect the hydraulic connector "Return line" (4) to a free return port of the tractor.
5. Connect the hydraulic connector "Flow line" (5) directly to the hydraulic pump of the tractor.
Open the pressure regulator via the load-sensing screw in the electro-
hydraulic control block when the hydraulic connector "Flow line" has
been connected to the control device of the tractor. Unscrew the load-
sensing screw as far as it will go for this purpose.
Disconnect the load-sensing control line from the load-sensing
connector of the tractor before operating the machine with free
pressure regulator.
