Hi my name is***** will be glad to help. Check the hydraulic filter for fine metal/debris indicating a component failure. Check the swing motor hose ports for metal( metallic glitter) indicating a failure. If found the swing motor will need to be replaced and the metal contamination cleaned out of the valves and system components. Also check the swing gearbox oil and if dry you could have a failed swing gearbox. If this is the case, it needs to be removed to allow the boom to be swung using another machine. Let me know
