The thread tension becomes tighter as the dials are tumed to higher numbers. The tension settings shown on this page as well as throughout
the Instruction book are suggested guides.
Adjust thread tensions to suit the fabric and size of thread of thread used. For best results make tension adjustments in small increments of no
greater than half a number at a time.
