Hi guys great site! Just got a 763G it doesn't have a operators manual. I have no experience with modern skid steers. I looked thru this site as much as I can but can't figure out what's going on with the Aux Hydraulics. I have the arm bar down the park brake off flow button pushed with light on. Push the button for the aux hydraulics and the engine dies. It will start right back up but as soon as I try the aux button it will die again. Any help would be much appreciated. Thank You Daryl
