I fear that water would lead to corrosion, and not provide the lubrication required in machine like that. There is a possibility it could be air over hydraulic.
Looking at the mechanism for clues got me wondering about the controls. What caught my eye is this vertical bar. It appears to move up and down with the ram. Perhaps actuating that weighted lever to limit downward travel. At the red arrows, the bar appears to be attached solid. The bottom red appears to push that lever down, perhaps stopping travel at a set limit. At the yellow it appears to slide. It must slide down through the base casting into the floor to allow that much travel.
