DESIGN AND FUNCTION
Working hydraulics Transport position
The cutting unit is in suspended position during transport. The two valves (3+4) on the valve block, which
regulate the pressure in the lifting cylinder, are closed. The hydraulic oil, which comes from the control unit,
passes through a valve (2) on the valve block and the oil is piped to the hydraulic pump for the drive sys-
tem. There, this pressure is regulated to 1.8 MPa (18 bar).
