Instructions for Use:
- Remove the bobbin case from your machine. Be sure the bobbin thread is out of the pigtail and place your bobbin case with the bobbin in it into the gauge slot. Snap the bobbin case in place.
- Wrap the bobbin thread around the two pulley wheels and around the plastic hook end on the gauge.
- Steadily pull the thread and note the reading on the gauge. This represents tension readings in grams. Correct bobbin tensions should be 180 to 220 grams.
- Adjust the bobbin case spring tension screw as needed to get the desired reading.
Note: The gauge needle should provide a steady reading. If you experience a bouncing, erratic reading it can be due to a dirty or defective bobbin case
