How to adjust the presser foot of a synchronous sewing machine

1. The height of the presser foot of the sewing machine can be adjusted freely. Along the presser foot bar upwards, there is a nut at the top of the machine head to adjust the height of the presser foot, press a piece of fabric, and then adjust the nut while turning the sewing machine until It’s fine as long as the cloth can be fed.
2. The adjustment requires tools such as screwdriver and opener.
3. Turn on the sewing machine and remove the pressure adjustment button.
4. Expose the presser foot bar, raise the wrench, loosen the screw located in the middle of the presser foot bar, and adjust the required height.
5. Tighten the screw in the middle of the presser foot bar just now.
6. Install the pressure adjustment button and turn off the sewing machine. Of course, the presser foot lever must not be misaligned.
