2. Hold the new bobbin with the thread coming over the top and to the right in a clockwise fashion. It
should look like a number nine (9).
3. Without flipping the bobbin, drop it into the bobbin case.
4. Route the thread through the thin slot opening and under the tension spring but stop before
threading through the pigtail. The bobbin thread should now be releasing from the side of the case.
5. To check the bobbin tension, hold the bobbin thread with one hand. As you gently bounce the thread,
the bobbin case should drop 1"-2" or 2.5 - 5cm.
6. If the tension is incorrect, use a flat-blade screwdriver to turn the larger adjustment screw clockwise
to tighten or counterclockwise to loosen the tension.
This test must be completed BEFORE winding the thread through the pigtail.
7. Once the tension is set, wind the thread through the pigtail.
For a more accurate test of the bobbin tension, use a bobbin tension gauge.
