I adjust the tension whenever I change to a different wt of thread and a different needle. I start with it where it is and adjust as needed. When doing decorative stitching I have to adjust it for the different stitches even when using the same thread and needle size. I don't mind adjusting tension control on any of my machines. It doesn't scare me at all. I had to get a new tension screw for my Bernina bobbin. I wore it out. LOL
