> Place the filled bobbin on the swiveling spool holder.
> Add the appropriate spool disc.
> Place the thread spool.
> Thread the 3 threads up to the upper thread guide.
> Guide 2 threads past the thread tension discs on the left and to the thread guide above the needle (see
page 44).
> Guide 1 thread past the thread tension disc on the right and to the thread guide above the needle (see
page 44).
> Thread the first thread into the left needle manually.
> Thread the second thread into the center needle manually.
> Thread the third thread into the right needle manually (see page 47).
Winding the bobbin thread
The bobbin thread can be wound while sewing if the swiveling spool holder is used for winding.
> Place a foam pad on the spool holder.
