Shandong 30, hydraulic oil should be changed, and the replacement of oil is not the same?
The same as changing the oil, the oil needs to be removed, cleaned and washed with gasoline
Under the hydraulic tank there is a small rope, (do not know if you are not the same as you have, you see), take the next line of wire, put the oil, and then add the new oil, just 3. That's how we change the oil.
