Sucking the fluids out the top rather than jacking it up, get a catch pan, wrenches, etc. Is so much faster. I will often build a dike with a tarp around the hydraulic equipment I work on. Because at work oil spills are a big deal, and when hydraulic fail it is usually a big mess. I can take stuff apart and not concern myself with all the fluid loss since I can pick up the edge of the tarp and drain it all to one side and then suck it all up without any hitting the ground.
