This is an awkward one.
Your employer may want the machine manufacturer to know of a problem with their machine and how injuries can occur so they can fix the problem. Assuming you are following the training you have been given then there is no reason not to co-operate although I don't think you need to go into a lot of detail about your injuries, it should more be about 'how' the injury happened (ie incident report), not about you as an individual.
However I do not know the extent of your injuries or the progress of any workcover claims so I am hesitant to say definitively one way or the other.
