Thanks! I have a few questions.
1. What is the screw knob looking thing on the top left for? I can screw it clockwise or counterclockwise. It looks like it's some kind of adjustment, buy my manual says nothing about it.
2. If the thread is twisting or balling up at the needle while sewing is that caused by user error? My wife keeps trying to force feed material through and I keep telling her that's what the feed dogs are for.
Thanks again!
