I bought an old Lc80 excavator.....it works ok when it is cold....a little weak on the hydraulics, but when the oil heats up a little things move slower and has no power......only the swing seems normal.....if you jerk the levers hard it will react.....but if u ease the levers slowly it seldom moves anything.....I am thinking the pressure relief valves are bad or set to low.......I have not put a gauge on it yet.......is it possible the hyd oil is the wrong type?.......does anyone have experiance with these machines?....... I would appreciate ant help......thanks, John.
