Well i purchased a yanmar vio45-5 with 240 hr on it from a rental yard and the hydraulic seem to be a bit slow, so would they have turn down the pressure on the pump or reset pressure valves? Because when i'm digging in hard dirt and i pull the dipper arm and roll the bucket and then pull on the lever to lift the boom it wont lift until i back off on the arm and bucket. but it only doe it in hard digging and when cold I have to pull the boom lever nearly all the way back and then it lifts.:Banghead:Banghead
