THREAD TENSION
Generally, thread tension should be controlled by the thread tension dial. Bobbin thread tension has been adjusted
at the factory and readjustment is rarely needed. Bobbin thread tension is just right when you can pull the thread
from bobbin case easily with a little resistance. Top thread tension may be adjusted by tightening or loosening
the thread tension dial, if necessary.
Properly adjusted thread
tension for straight sewing
The needle thread and the bobbin thread
should interlock in the center of two layers of fabric
How to adjust the bobbin
thread tension
The bobbin
thread ap­
pears on the
upper surface
of the fabrics.
The needle
thread ap­
pears on the
underside of
the fabrics.
Loosen the needle thread tension by
moving the dial to the lower number
Tighten the needle thread tension by
moving the dial to the higher number.
To increase tension,
turn screw clockwise.
To decrease tension,

There are several reasons you might reset your tension. The best tension for one fabric may not be correct for
another. The required tension depends upon the stiffness of fabric, thickness of the fabric, num ers o y
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.
