Glad to hear the machine is running. Those lines that run toward the right of the combine and sort of above the big electric clutch pulley should be for the hyd drive reel. They go to the flow control valve (the dial on the right when your sitting in the seat). Make sure when you go to run the feeder house that either those hoses to the reel are hooked up or the short hoses with couplers under the cab that the reel hoses hook to are coupled together. Either way you need to make a complete circuit so the oil circulates. Otherwise the pressure buildup will cause the relief valve to open and prolonged running like that can cause pump failure. That reel drive pump only runs when you pull the switch to engage the feeder house so as long as you have the switch pushed in you can run the seperator without worring about it.
