Had a hyd. hose blow....fixed hose and hooked everything back up and filled with oil. Had to pull several hoses to find blown hose under hyd. tank. but all functions worked the right way.....just very slow except for swing that wouldn't swing at all. Symptoms worse now, seems pump is loading engine constantly. I have checked several valves on top of valve control to see if they were stuck and all seem ok. I am also getting a CPU warning in cab now. I am no hyd. expert but I feel I might have bad sensor on pump that wont let it de-stroke. Any help is much appreciated.
Have a look at lcd screen on cpu, it will have a fault code on it.
