Singer H74 - Thread Tension; Thread Tension Adjustment Guide

- Basic thread tension setting is "4". To increase the tension, turn the dial to the next number up. To
decrease the tension, turn the dial to the next number down.
- Proper setting of tension is important for good sewing. There is no single tension setting
appropriate for all the stitch functions and fabrics. However, 90% of all sewing will be between
the "3" and "5" ("4" is the basic setting).
- For decorative sewing you will always obtain a nicer stitch and less fabric puckering when the
upper thread appears on the bottom side of your fabric.
