What if the home sewing machine is not online?

There are several possibilities for sewing machine jumper.

1) If the needle is bent or installed backwards, replace it with a new needle or install it correctly.

2) If the tension of the take-up spring is too high or there is no fault caused by the take-up spring, it can be solved by loosening the take-up spring and installing the take-up spring.

3) If there are burrs on the shuttle tip of the rotating shuttle, gently grind them off with fine sandpaper.

4) Failure caused by excessive position error between the shuttle and the needle can be solved by adjusting the position of the shuttle and the needle.

The specific operations are as follows: a) Adjust the up and down positions of the needle and the shuttle. First rotate the needle to the lowest position, and then continue to rotate slowly. When the needle moves up slowly, the shuttle tip should just move to the middle of the needle plane. If it's not right, it's ok. B) After the adjustment of A is completed, the position between the needle and the shuttle tip can be adjusted. The operation is as follows: adjust the distance between the tip of the shuttle and the needle to 0~0. 1mm, and then tighten the fixing bolt of the shuttle.
