A little more info as to what it is not doing would help. but I think you are saying that it does not pump up anymore, either by foot pedal or air?
Either the hydraulic seals have failed in the pump and or piston (not surprising after 9 years) or you have lost hydraulic fluid. Not sure but someone recently mentioned getting their lift repaired. Andy
Most pump seals are easy and available from any hydraulic supplier .Look in your area for a dealer who can repair it or do it yourself

The pin in the linkage between the pedal and hydraulic ram wore thru on mine. Replacing it was a bit of a nightmare cos it operates so close to the chassis. Unless it's going up and down like a frog up a pump I would have thought seals are unlikely, especially without the witness of oil. TB
Mine stopped lifting after a few years and there was a small amount of fluid leaking from it. I got a Clarke seal kit from Machine Mart which sorted it out.
