My Power Pole uses a Parker hydraulic power unit. You might look on the Parker website.
You might want to reconsider switching oil, if your unit is leaking, I think the "green" hydraulic oil will be a lot easier to cleanup in you bilge.
I bought a quart of Green hydraulic fluid for $13. a couple of months ago. I think you need to do a little shopping.
