I added to much hydraulic oil to my 200D. Its 1.5 inches over the full mark. Should I drain it down to middle of operating zone or leave it? In Ag tractors the manual says if hydraulic system is over full it will cause oil to over heat. What will overfull do to the excavator?
Ag tractors the oil tank is the transmission. To much oil, to much frothing. Your machine has a separate, sealed tank. It is possible the oil reservoir may overpressure when the oil gets hot since there isn't enough empty space.
