Winding/Installing the Bobbin
CAUTION

Winding the bobbin

This section describes how to wind thread onto a bobbin.
Memo
• When winding the bobbin for sewing utility stitches,
use thread appropriate for the fabric that you wish
to sew (page 27). Normally, the thread will be the
same as what is used for the upper threading.
• When winding bobbin for embroidery, be sure to
use the recommended bobbin thread for this
machine.
a Open the top cover.
b Place the bobbin on the bobbin winder shaft so that the
notch in the bobbin aligns with the spring on the shaft,
and then slide the bobbin winder shaft to the right until
it snaps into place.

Memo
• By placing the bobbin into the bobbin case in the
same orientation that it was on the bobbin winder
shaft, the bobbin can be installed with the correct
winding direction of the bobbin thread.
The "b" mark on one side of the bobbin included
with this machine can be used as a reference.
Remove the spool cap and place the spool of thread for
the bobbin onto the spool pin.
Slide the spool onto the spool pin so that the thread
unwinds to the front from the bottom. Otherwise the
thread may become tangled around the spool pin.

Slide the spool cap onto the spool pin.
Slide the spool cap as far as possible to the right, as
shown, with the rounded side on the left.
CAUTION
• If the spool or the spool cap is not installed
correctly, the thread may become tangled
around the spool pin, and the machine may be
damaged.
• Three spool cap sizes are available, allowing
you to choose a spool cap that best fits the size
of spool being used. If the spool cap is too
small for the spool being used, the thread may
catch on the slit in the spool or the machine
may be damaged. When using mini king thread
spool, use the thread spool insert (mini king
thread spool).
For details on thread spool insert (mini king
thread spool), refer to "Memo" on page 21.
