Before hooking the lines up to my machine I took the hydro lines off to make sure there was no water or anything in them. The lines coming from the part of the cylinders that were open/extended had a few drops worth. This was shipped dry. Now I did open and close the cylinder by hand by lifting the grapples up several times after greasing. I wonder if by doing this I created a little condensation in the closed system. Amount of water was drops, and when blowing air through you could see a little fog blowing out. This is the first time I’ve bought equipment with dry hydraulics. Usually the dealer hooks up to equipment during prep.
