1. The jumper is that the gap between the crochet and the machine needle is wrong. Treatment method: remove the crochet panel, and there is a manual rotating hand wheel behind the sewing machine motor. Manually rotate the hand wheel to see where the crochet can hook the line, and lock the crochet at this position.

2. How to adjust the broken wire is that the wire quality is poor, and the wire presser is too tight. Treatment method: the wire presser has a plastic knob on the top of the wire passing ring, tighten it clockwise and send it counterclockwise, and adjust it to the appropriate position. If the wire presser is not tight, the wire quality is poor, and it is OK to replace the wire.
