Preparing for Upper and Lower Threading

Winding the bobbin

Wind the thread onto the bobbin.
CAUTION
● The included bobbin was designed specifically for this sewing machine. The machine will not operate
correctly if older model bobbins, which have a different thickness, are used. Use only the enclosed
bobbin or bobbins of the same type. Using a bobbin other than the one designed specifically for this
machine may result in injuries or damage to the machine.
a Turn on the sewing machine.

Fully insert the spool of thread for the bobbin
onto the spool pin.
Slide the spool onto the pin so that the spool is
horizontal and the thread unwinds to the front
at the bottom.
CAUTION
● If the spool is not positioned so that the thread
unwinds correctly, the thread may become
tangled around the spool pin.
