It's a 2002 and the right overpressure relief valve on the travel motor relieves when i try to move the machine. I just bought the excavator so I don't know much about it yet. Can someone please give me an idea what could be causing the issue? I have the service manual but it isn't too much help. Looking for typical causes and solutions. Thanks
Good day It may be as simple as switching valves and compare the difference attached a file I hope it is of help. Kind regards Uffex
