I don't know how useful this answer will be but not knowing the Woodfast I Googled a picture of it and one answer showed it's made my Qingdao in China.
Now that makes me think it's one of the multitude of lathes like my Axminster 1200D but which are sold under various brand names worldwide. It's also highly likely that at sometime Axminster sold their variant. They have the AWVSL1000 Woodturning Lathe version at the moment but probably not identical to what you are looking for.
So just as a suggestion, have you asked them if they ever have sold their version and if so do they still have a manual for one?
