Dynahoe D160 operating issue.

I have recently purchased this Beast of a machine and my issue is, to me the hydraulics on this is wide open. Even at idle any movement of the controls is fast. Just barely pulling or pushing on controls it's like normal operating speed on most other equipment. There is not any finesse to it. Any movement past 1/4 throw and its wide open. My question Is there a pressure regulator for it and what psi does it need to be set at.
 

I wouldn't say it is a beast, but it certainly is not a compact tractor with a hoe and will not act like one. Those machines were not the most sophisticated but they would dig. They perform best at 3/4 throttle and above, where they were intended to run.

That sounds like the hydraulic pump is good, that is a plus. There is a main pressure relief valve; however you do not lower the relief pressure setting to slow it down. Speed is volume, pressure is force. If you lower the pressure you will lose hydraulic power and it will likely be just as fast.

I have to believe your Dynahoe is operating properly. The control valves on the hoe are not intended to just be pulled or pushed fully open every time you move one. Operators feather the controls. Another thing that usually slows and smooths them is to work two functions at a time. After you spend some time operating it, you will learn to feather the valves. JMHO
 
Pressure is not the issue, volume of flow is. Many machines are built with maximum performance in mind. Positive displacement pumps can only change volume by being slowed down. Variable displacement pumps can modify volume using a control lever or other servo mechanism to dynamically change output. Almost never are restrictions placed in hydraulic lines because they waste power, and create heat. (some are used to limit drop or movement, but they are safety devices).
I do not know what king of pump is used, but one or the other of the above is likely to need modification to slow things down. If it is variable, there may be a lever, or knob, or? in the cab that changes the flow volume. I hope others can give more direct information. Jim
