Sunday I tipped over my b7610. It wound up on it's left side. I wound up in the ER. major large bruise on right leg and severely bruised pride. I lost some hydraulic fluid so I called the dealer today to find out how much the new stuff costs. I then mentioned that I tipped it on it's side. The dealer then said I needed to drain and replace all the fluid. Do I really need to do that or can I just top it off? All the other fluids seem fine.
