Yes just had a look and the top roll pin has snapped, bashed it back in for now, it might hold.All fairly simple really, what is wrong? Ours went very wobbly and just needed new roll pins
The roll pins are a odd size, best to get genuine ones from dealer I dont think they were expensive.
Can you knock them in without splitting the machine?Double pins, a smaller one inside the larger one, and coated with threadlock. They will come out again otherwise.
