Adjust Thread Tension - IKEA Sewing Machine Instruction Manual

ENGLISH

Adjust thread tension

If you need to adjust the thread tension, you usually only have to alter the
top thread. The bobbin thread tension is set during manufacture, and any
adjustments are only required for special threads and fabrics.
1. In a perfect seam, the threads are locked between the layers of fabric.
2. If the top thread tension is too tight, the bobbin thread appears on the
right side of the fabric. Decrease the thread tension slightly to solve the
problem.
3. If the top thread tension is too loose, the top thread appears on the back
of the fabric. Increase the thread tension slightly.
Adjust the bobbin thread tension
In the unlikely event of you needing to increase the ten-
sion of the bobbin thread, you can turn the adjustment
screw on the bobbin case to the right. If you need to decrease the tension
slightly, turn the screw to the left. You can test the tension of the bobbin
thread by pulling the thread out of the bobbin case.
If you feel slight resistance, the tension is correct.
TIPS! Most fabrics require tension between 3 and 5. Try sewing on a scrap
of fabric first so that you can adjust any settings if necessary before using the
"proper" fabric.
