Check the oil level with the cutterbar rams retracted. Oil filter Working hydraulics = sieve filter in the tank (60 µm) Steering hydraulics = sieve filter in the tank (60 µm) Hydrostatic drive = filter cartridge (10 µm) Change filter yearly or every 500 operating hours whichever is sooner. Oil pressure Working hydraulics = 175 +15 bar, back pressure 3 +6 bar Steering = 160 +15 bar, back pressure 10 +7 bar Low pressure hydraulics = 19 +4 bar High pressure ground drive = 420 +30 bar Charge pressure ground drive = 30 ± 2.5 bar Chaff spreader / straw spreader = 175 +15 bar Uni-spreader = 55 +15 bar Note:
These figures are to be measured, when the hydraulic oil is at a working temperature of approx. 60°C General hydraulic problems Hydraulic tank overheating Excessively high back pressure in the system (p max back pressure - Check the spool operation in the returns valve - Check the hydraulic pipes for kinks - Check the return filter for cleanliness Note: If the machine is equipped with Autopilot, then also look in the chapter on steering hydraulics. 11/2001 1-3
