9. Settings

The tension in the upper and lower thread has been set correctly if no twining of the thread is visible on the top or on the underside of the material after sewing.

If the tension on only one of the threads is set incorrectly, the resulting seam will be untidy. The stitches lie flat on the material, seams are not formed and the material is not drawn through.

a)Setting the upper thread tension

You can use the thumbwheel for the upper thread tension to set the tightness of the upper thread. If this thread is ...

-too tight (higher setting), then the upper thread is loose and the mate- rial is being 'sewed' with the lower thread only.

-too loose (lower setting), then the lower thread is loose and the mate- rial is being 'sewed' with the upper thread only.

The upper thread tension is normally set between 4 and 6.

b)Setting the lower thread tension

You can turn the screw on the bobbin case to set the tightness of the lower thread. Turn it ...

-clockwise to increase the tension.

-anticlockwise to reduce the ten- sion.

The lower thread tension has been set correctly if the bobbin case unwinds slowly and evenly ("Drop test").
