case 580 super m slow hydraulics

drives down the road fine with power. power steering is normal. every function of the dipper is slow. stabalizers pick up the rear end but i dont think as much as they should, loader moves a little faster but still dont think as it should. seems a little better as it warms up. changed fluid and filter. is there a suction screen in the tank? have yet to do a pressure test. I'm doing all the little things i can before i take it to my mechanic. Any thoughts would be appreciated!!

    Check your regeneration spool and poppet items 2 and 3 and item 4 spring. They are located in the outlet section which is on the left side of backhoe control valve as you look at it from the back of the machine.

    Another place to check is the main relief in the loader valve. I have found some with debris in them holding them open.
