So operator tells me that the hydraulics on the upper motor are not working wont travel or boom wont do anything. Anyone seen this issue or can give any pointers were to check the pressure at the pump. All I know right know that the switch on the arm rest is working when you push the arm rest down also the coupling that mounts on the flywheel and engages pump seems to be good.
