I have a kobelco sk125sr-2. It working well. But now a days i have noticed that when the machine is in boom up position the arm piston rod out itself slowly. Can any one suggest me how to solve the problem
Good day From the description, I have interpreted that the arm cylinder creeps out with the boom raised, resulting in the bucket travel towards the cabin. If this is correct the machine has internal leakage, you can plug the negative cylinder line with the equipment rested, raising the boom if the cylinder holds the leakage is at the main control valve. Hope that helps Kind regards Uffex
