[. . . ] Hold the ends of the threads between the fingertips of your left hand, slowly turn the handwheel 6 two or three times towards yourself and then check the threads once again. The thread tension required is variable, being dependant itself on the type and thickness of the thread and fabric. check the seams and then adjust the appropriate thread tension on the machine. Tensioning the thread When you turn the tensioning device to a lower number, the tension reduces. When you turn the tensioning device to a higher number, the tension increases. Lay the material for a trial run under the sewing foot o and slowly start to sew. When the task is complete, continue sewing until an approximately 5cm (2") long length of threads has formed at the end of the material. The tread tension on the left needle is too loose.

When necessary, adjust thread tensions as per this table: Thread tension adjustment With the following procedure, changing threads is quite simple: 1. Cut the yarn above the spindle and knot the ends of the new and the old thread together. Pull on the other end of the yarn until the knot passes under the sewing foot o.
