To adjust the tension on a Kansai sewing machine, follow these steps:
1. Start by turning off the sewing machine and removing the fabric and thread from the machine.
2. Locate the tension dial on the machine. This is usually located on the front or top of the machine near the thread guides.
3. To increase the tension, turn the tension dial clockwise. To decrease the tension, turn the dial counterclockwise.
4. Test the tension by sewing a few stitches on a scrap piece of fabric. Check the stitches to see if they are balanced and even. If the stitches are too loose or too tight, continue adjusting the tension dial until you achieve the desired result.
5. Once you have adjusted the tension to your liking, rethread the machine and resume sewing.
6. It's important to remember that the tension may need to be adjusted depending on the type of fabric and thread you are using, so be prepared to make further adjustments as needed.
