Hi,It is Dan. I will be glad to try to help. If swing is the only slow function then I would check the swing relief valves in the main control valve and also for excessive case drain pressure in the swing motor indicating a worn swing motor. Try swapping the reliefs with another circuit to see if the problem moves to another circuit with them. Also look for fine metal/debris in the return filter. Let me know
