Adjusting the Thread Tension

The tensions of the upper thread and of the bobbin thread (thread tension) should be adjusted so that they are 
equal.

Changing the tension of the
upper thread

If the thread and needle combination is correct for 
the type of fabric being sewn (according to “ Needle 
types and their uses”  on page 30), the thread tension 
will automatically be adjusted to the appropriate 
setting. However, if the preset thread tension does 
not give the desired result or if you are sewing with 
special thread or on special fabric, use the thread 
tension dial on the left side of the machine to adjust 
the tension of the upper thread.

■

Correct thread tension

The upper thread and the bobbin thread should 
cross near the center of the fabric. Only the upper 
thread should be visible from the right side of the 
fabric, and only the bobbin thread should be 
visible from the wrong side of the fabric.
