Inspect the hydraulic install carefully first to determine problems or potential problems in the current system. Things to look for would include jagged holes for cylinders cut with a torch, birds nests of wiring, pump and battery mountig issues, rubbing hoses or cylinders etc. If it checks out go ahead and change the oil, cylinder seals and add some new batteries and see how it works. Make sure you have a disconnect installed if there isn't one already there before you start playing, could save a fire if there is an electrical problem. The guys from Hydroholics are on here as well if you have more questions. They are very knowledgable on the subject and their product line is top notch , check 'em out.
