The stitches of the sewing machine are adjusted to the maximum, but the stitches are still small. What happened?

It depends on the stroke of the teeth, that is, from front to back, and the distance of needle feeding. If the distance is not large enough, please adjust the needle wheel to the maximum. Loosen the screw in the middle of the dial. Adjust the needle wheel to the side with small needle number, and then tighten the screw. Finally, adjust the needle size.

1. If the needle distance button and needle of the sewing machine have been adjusted to the maximum, but the needle distance is still small, check whether the feed teeth are too low, and adjust the height of the feed teeth and the tightness of the presser foot appropriately.

2. When the side cover is opened, there is a needle code adjustment button on the front. When the button is stuck in the slot, the handwheel rotates forward to increase the needle size, and vice versa.

Matters needing attention in the use of sewing machine:

1, the power button and pedal cannot be used at the same time;

2. The rectifier and dry battery cannot be used at the same time, which will damage the sewing machine;

3. If the battery is not positive or negative, the machine will reverse, and the reverse sewing machine will not be able to sew;

4. Continuous reverse rotation of the machine for a long time will damage the sewing machine;

5, can't use good quality, too thick fabric;

6. Please use four 6V 1.0A or No.5 batteries for the rectifier.
