4. The bobbin should rotate counterclockwise when the thread is pulled when properly threaded
under the tension spring.
NOTE: The rule is for the thread to backtrack as it comes off the bobbin under the tension spring.
It should rotate the opposite way it is wound. It should not rotate the same direction it is wound.
To test Bobbin Tension
The bobbin tension is the foundation for stitch tension. Always set the bobbin tension first.
NOTE: Check the bobbin tension each time a new bobbin is inserted.
1. With the bobbin properly in the bobbin case, hold the bobbin case in the palm of your hand with the
open end facing up.
2. Wrap the thread once around the index finger of the opposite hand and attempt to lift the bobbin
up by the thread. The bobbin case should stand up on its side, and barely lift out of your hand. If the
bobbin will not stand up on its side, the bobbin tension is too loose. If it lifts completely out of your
hand and hangs by the thread, the bobbin tension is too tight.
To adjust the Bobbin Tension
• Make the adjustment using the screw in the center of the tension
spring (the larger of the 2 screws). Turn clockwise to tighten and
counterclockwise to loosen the tension. Make tiny adjustments
to the screw and test again.
2. T
he thread will then backtrack through the slot.
3. Guide the thread under the bobbin case
tension spring.
