Follow up question and I'll try to be clear, but I don't know all the technical terms.
The line that needs to be replaced is the one that goes to the fitting at the top, or the head of the cylinder, as opposed to the fitting at the base of the cylinder. My best guess is that this line should make the cylinder retract thus retracting the slide. If the cylinder is extended, this line should have no pressure. Would that be correct, or is my logic backwards?
If I'm correct, then with the slide extended I should be able to just loosen the connections without spraying hydraulic fluid all over my new driveway. I'm sure I'll lose some, but it shouldn't spray out, correct?
Thanks for the help!
