Tail lift wont go up or down - whirring

daesal:
Great. Thanks for your replies. It is a hydrolic life.The truck is level but it might be low on fluid. I can’t see a reservoir. There is what could be a small tank behind the motor?
I will get some hydraulic fluid and then try priming.
Thanks . Will post how I get on

STOP! Call a fitter/company or whoever. (Just my advice). Hydraulic systems only go low on hydraulic oil if there is a leak.
