Bobcat 632 Hydraulic System Flush

[Sniper6]

Hello all. My first time posting. I have been rebuilding a 632 that has been sitting for a long time. I plan on changing all of the hydraulic hoses. I've read that a person should flush the hydraulic system periodically. How do I flush the system and what should I use to flush it? I have read on the forum that you should use a flushing fluid before adding the permanent hydraulic fluid.

I would guess a lot of it depends upon is the oil just old or is it contaminated with water or other issues, It is difficult to get it all out,most try to just exchange as much as reasonable possible with the suggested fluid. You can use a cheap version of oil to flush the system and refill with the correct fluid if need be in the case of water.
