MM uses a hydraulic cylinder for the setworks.The valving is such that when the valve is closed the the cylinder is locked from both hydraulic lines.The challenge I found with the Mighty Mite was manually stopping one the scale. In this type of manual setworks there is a minimum time the valve will open and hence minimum step size versus cylinder speed. The slower the speed the smaller the minimum step size. To control this issue I adjusted the hydraulic flow rate in the cylinder with two flow control valves.The advantage of this system is the matching lifting force on the sawhead, with a minimum of parts.
