See that little screw on the bottom? take it out and the whole piece drops down JUST A LITTLE BIT. Then I hope you can get the thread out. I JUST hope this is right. If you can't get the screw out, put a drop of oil on it and let it sit for a while, 1hr. Also, take the foot off the foot feed. It will injure it.
