I have a Kobelco SK140. it is a gray market machine and I purchased it used. it sat for a couple of years. now when i try to use it, I don't have any hydraulic controls for the tracks, cab, buck/boom. I do have controls for the thumb. The thumb was put on after. I was having similar problems before I parked it but a simple ground would solve the problem for a few hours. any suggestions? I think it is more of an electrical problem rather than a pump problem.
