I got my wife's FW for a lower price than what you normally see because it was locked up. One piece of thread behind the bobbin case base was all it took.
In my opinion people that are incapable of understanding normal maintenance as specified in the manual don't need to use that machine. I believe ( if I'm wrong I'll retract this ) that the FW owners manual covers the clearing of thread jams. I could look that manual is down stairs. So JoAnn, tell your friend to take it to a service tech cos it's way beyond her comprehension level.
Sorry bout the attitude, but that's the way I feel.
