[QUOTE="skidsteer.ca, post: 6426, member: 307"] Perry Pump is likely fine. Just set the relief where you want it but try to warm the hyd oil up b4 hand. I'd check where you have the pressure now and check again after you warm the oil to see if they read the same. Put a piece of cardboard over the oil cooler to block the air flow, run one of the hyd functions to the end so the oil goes “over the relief” and hold it on for a few minute to warm it up to 120 to 140 degrees. Then adjust your pressure to where you want. After 50 hrs or so and check it again. Relief valve springs may soften slightly after some use, you don't have to double check, but if you do and the press is staying put, then you know all is well. The hand controls on your machine, are they cables that hook the handles to the valves or are they electric over hyd? Regards Ken [/QUOTE]
