Hi I'm new to this forum and would greatly appreciate any feedback from the members here.I bought a older 5625 this past summer and a problem with the hydraulics has started.The pressure relief valve by the main control valve (tilt,lift valves started relieving pressure back to the tank one day.The next day it was ok again but that same week it started relieving again and it hasn't changed since.It will lift very slowly,won't go back down and the tilt doesn't do anything.Local mechanics aren't helping much,they want me to bring it to their shop.Big surprise!Can anyone help with this? Thx Randy
