REGULATING THE THREAD TENSION
Generally, should any tension adjustment be necessary, the adjustment can normally be made by regulating
the upper thread tension dial only. Bobbin thread tension has been adjusted at the factory and readjustment
is seldom required except for special instances, thread and fabric.
Bobbin thread tension is just right when you can pull the thread from bobbin case easily with a little resistance.
Thread tension may be adjusted by tightening or loosening the thread tension dial.

Remember the higher the number, the tighter the tension. Correctly balanced tensions for one fabric may not
be suitable for another. The required tension depends upon the stiffness of fabric, thickness of the fabric,
numbers of layers of fabric being sewn, as well as the type of stitch you are making. It is better to test the stitching on a scrap of the fabric you are using before starting to make a garment. The general range for many fabrics is 3-5.

FREE ARM SEWING
This sewing machine can be used like a flat bed machine, but easily
converts to a free arm machine by removing the extension table.
The free arm enables you to sew tubular types of pieces more easily.
Just slip the sleeve or pants leg on the free arm as shown above.
You will find many uses for this free arm feature such as:
1. Mend elbows and knees of garments more easily.
2. Sew in sleeves more easily. This is especially true when sewing
smaller garments.
3. Applique, embroider or hem around edges of cuffs or pants legs.
4. Sew in elastic casings in skirts or pants at the waist line.
