Setting the thread tension
If the thread tears while you are sewing, the thread tension is too high.
If small loops are formed when you are sewing, the thread tension is
too low.
In both cases, you need to adjust the thread tension.
The tensions of the upper and lower threads must be in the correct
proportion to each other.
Adjusting the upper thread tension
An upper thread tension of 3–4 is ideal for most
sewing work.
The tension is created by the discs through which the thread is
guided. The pressure on these discs is controlled by the upper thread
tension regulator

.
The higher the number, the higher the tension.
The upper thread tension is not activated until the presser foot is
lowered.
There are a number of reasons why you might need to adjust the
tension. For example, different tensions are required for different
fabrics.
The tension you require depends on the strength and thickness of the
fabric, the number of layers of fabric you want to sew and the type of
stitch you choose.
Please make sure that the tensions of the upper and lower threads
match, as otherwise the fabric may gather.
We recommend that you carry out a test on a scrap of fabric before
starting work.
Adjusting the lower thread tension
The tension of the lower thread is regulated by the spring on the
bobbin case. To adjust the tension use the multi-purpose screwdriver.
−
Turn the screw on the spring clockwise in order to increase the
thread tension.
−
Turn the screw on the spring anticlockwise in order to decrease the
thread tension.
