1. The actual thread tension varies in accordance with the kind or thickness of thread used even
when the set value of thread tension is the same. Especially, in case of thread of which the
surface is hard to slide, the thread tension becomes higher, and even when the set value is as
low as 60 to 70, the loop becomes smaller. As a result, stitch skipping may be caused. When
using plural threads, it is recommended to make a sewing pattern to which set values of thread
tension suitable for the respective threads have been inputted.
2. When the needle thread tension (No. 52) at the end of sewing is set to a high value, stitch
skipping at the end of sewing or failure of needle thread take-up may occur.
