We got a 930k and when under pressure it don't lift or tilt. By itself it lifts and tilts fine. It even works with a light load. But once you try and pick something heavy it will probably just lift a foot or 2 off the ground. Vin- "cat0930khrhn02121
Pressure = Power Flow = speed You will need to put the appropriate Pressure gauge on the control valve and tell us what it is. It sounds as though you are not getting enough pressure from your pump. But without knowing what the system pressure is while experiencing the problem. It would be tough to tell you where to start looking. If you do not have experience with hydraulics and the dangers associated with it. Then stop what you are doing and call someone who does.
