7-4. Threading the bobbin case
Turn off the power switch before removing or inserting the bobbin case, otherwise the machine may operate if
the treadle is depressed by mistake, which could result in injury.
1. Insert the bobbin into the bobbin case as shown in the illustration.
Note: If the bobbin is inserted back to front, the bobbin will spin freely and the work clamp pulse motor will get out of
step.
2. Pass the thread though the slot (1) and then under the tension spring (2) and through the slot (3).
3. When sewing whip stitches, pull approximately 40 mm of thread out from the thread hole (4), and when sewing purl
stitches, pull approximately 40 mm of thread out from thread hole (5).
