Hello I'm looking for advice on how to change hydraulic fluid in homemade wood splitter that I got. After motor blew it sat for many years unused outside before it was given to me. I replaced the motor and tires and got the rust off the beam and rebuilt the Pusher block so now everything works. Since it was homemade there is no manual and I have not changed hydraulic fluid on a splitter before. Fluid looks okay but I would rather start fresh so I know what I have no telling how long it's been in there. do I have to get fluid out of RAM, or just drain the tank. How do I keep air out of the hydraulic lines and if I do get air in them is that a problem?
