The liquidiser(A788) is an attachment for a Chef A 701A. The blade hub assembly is very stiff in rotation. Please can you advise on how to free up the blade assembly? Otherwise please could you advise if there is a compatible replacement unit currently available

I have bought and had to return several so-called replacement bases for this model. I even have 'a little man that does' who modified a modern nylon fitting for me but that has locked up so think I'll be giving up on it now.
Hope this helps you.
