It is recommended that a test sample be made on a fabric scrap before sewing on your project.
The basic thread tension setting is “5”.

The lower thread tension has already been adjusted at the factory for general use. For most sewing applications, no adjustment is needed. When sewing with thin thread on thin fabrics, the thread tension can- not be adjusted adequately with the upper tension control dial. There- fore, the thread tension must be adjusted according to the procedure described below.
CLower tension is too loose.
Locks appear on the surface of the fabric.
Decrease the thread tension by turning the dial to a lower number. If the result is still not satisfactory, then adjust the bobbin thread tension as explained in
C-1 Bobbin
Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the screw more than one full turn.
Remember to return the screw to its original setting before start- ing your next project.
DCorrect tension
Correct tension is important since too much or too little tension will weaken your seams or cause puckers in your fabric.
