Thread Tension Adjustment
Thread tension can be adjusted from either the top thread tension
adjustment or the bobbin case screw adjustment. If you see
bobbin thread on top, you may need to adjust the tension.
However, before you adjust anything, check to see if the thread
may be caught and not feeding properly. Next, check to see if the
machine is threaded correctly. Change the needle. This could also
a ect the tension. Adjust the tension only if these suggestions do
not correct the problem.
Adjust Upper Thread Tension
When making tension adjustments, always start with the top thread. If
bobbin thread is showing on the top of the design, this means that
the tension on the top thread is too tight or the bobbin adjustment
is too loose. To loosen the top thread tension, rotate the Thread
Tension knob to the left (to a lower number).
If the stitches are not setting properly in the fabric or if loops appear,
you may need to adjust the tension so that it is tighter. First check
to see if the machine is threaded correctly before making any
adjustments. If threading is correct, turn the Thread Tension knob
to the right (to a higher number).
The standard position of the tension should be between 4 and 6 as
noted in the dark area of the Thread Tension knob.
