200 series are Joystick systems. That means the JOYSTICK is the only release of fluid. Since BOTH jacks do not retract, then the Joystick is probably not the problem. There are 4 needle seat valves at the Joystick control. 1 needle for each jack. Do the Jacks retract and the swing up horizontal (called kick down jacks) or are they straight jacks? If Kick down, make sure they clear the ground, because if they retract the cylinder but do not lift OFF the surface, then they cannot kick up and then fully retract. IF you have kick down jacks, you can drive OFF of them by slowly inching forward and they will pull backward and they then swing horizontal. Check for pinched hoses. Doug
