Settings 11.8.2 Adjustment using add-on spool valve with volumetric flow control Precondition: The oil of the hydraulic sys- tem is at operating temperature.  On the implement: Completely open the flow control valve (1).  In the tractor cab: Set the desired speed or the mbar range via the volumetric flow control adjustment of the add-on spool valve.
Page 111 Settings  To determine the speed fluctuation, ac- tuate the auxiliary consumer (e.g. track marker or lifting device). To ensure that the required quantity of oil is available, pay attention to the in- creased engine speed of the tractor.  If the pressure continues to drop by mo- re than 10 mbar or the speed by more than 750 rpm: Repeat the process.
