Hello Bernard,
I think you are getting a false impression on your machine, something else is causing the thread to break unless you are putting the thread round the tension twice, make sure you have threaded the machine properly with the presser foot up so the thread goes between the discs, top tension between 4 and 6, make sure you have the needle in the correct way round.
