Thanks for the replies. I will try to get pics. We have a strict protocol for publishing photos so it may take me a few days. Some specifics, there is a bladder type accumulator that sits on the counterweight I believe this is a shock absorber for the entire system. Tucked into the manipulator itself are 3 piston type accumulators. The easiest to see is the the hydraulic line that tilts the manipulator "up" is tee'd right at the piston fitting, the tee'd line runs to the bottom of one accumulator where it tee's again and it is valved. When the valve is closed the tilt operates as it should. Opening the valve and the manipulator starts tilting down with moving a control lever. So, valve closed puts the accumulator at the end of the line and allows it to act like a shock absorber. So why is there a valve then? To flush the lines perhaps and ensure that there is no air in the line leading to the accumulator? It is a mystery at the moment. I will post some pics when I get them. I know it is hard to describe without visuals.

My bad, location added. Now for those specific suggestions But seriously, this is a nice piece of equipment that has probably only done 4 or 5 forging jobs in 27 years and has always been maintained in a ready state. Zero wear and everything works as it should. The perplexing part is it has a system of hydraulic accumulators and valves that presumably act as shock absorbers. The manipulator has no springs and no one knows the correct way to adjust the valves.

Is any one here familiar at all with a forging manipulator made by Dynamic Equipment Corporation? Made in the 90's. Capacity is around 1600 lbs mounted to a fork truck. The one I have to use is mounted on a small Clark fork truck. I am looking for any type of operating or maintenance manual. I have exhausted google and searched several equipment archives. The original manufacturer is no longer. Any info would be appreciated.
