How to adjust the stitch length of DS-9C bag sewing machine?
It is to adjust the height of the toothed part under the presser foot. I forgot about that thing.
I also have the drawings, but I can’t always adjust the sewing machine to the factory-set 10 mm stitch length.

Be sure to remember that the 10MM stitch length cannot be changed, which is a dead number (I just found out that this stitch length is the distance between the needle and the bottom plate, and I kind of forgot about it). 38.5 can be fine-tuned. Adjusting the needle length eye-to-eye for the final destination requires adjusting the needle bar. He can open the gland and adjust it up and down. If you adjust your sewing machine based on experience. It is estimated that something will go wrong within a few days. If you adjust strictly according to the technical regulations. Guaranteed for half a month. So let’s read more information. Second picture from the right. Those angles of adjustment are also important.
