1 "Start/Stop" button
Note
• When winding transparent nylon thread on the
bobbin, stop bobbin winding when the bobbin is
1/2 to 2/3 full.
If the bobbin is fully wound with transparent
nylon thread, the pressure may create fractures
to the plastic bobbin. This will lead to irregular
stitches or possible breakage to bobbin.
o When the bobbin winding becomes slow, press the
"Start/Stop" button once to stop the machine.
When the foot controller is plugged in, remove your
foot from the foot controller.
CAUTION
• When the bobbin winding becomes slow, stop
the machine, otherwise the machine may be
damaged.
p Use scissors to cut the end of the thread wound around
the bobbin.
Winding/Installing the Bobbin

the needle will not move. (Sewing is impossible.)
r Slide the sewing speed controller back to desired
sewing speed position.
s Remove the spool for the bobbin thread from the spool
pin.
Memo
• When the machine is started or the handwheel is
turned after winding the bobbin, the machine will
make a clicking sound; this is not a malfunction.

Installing the bobbin

Install the bobbin wound with thread.
You can begin sewing immediately without pulling up the
bobbin thread by simply inserting the bobbin in the bobbin
case and guiding the thread through the slit in the needle
plate cover.
Memo
• For details on sewing after pulling up the bobbin
thread, for example, when making gathers or with
free motion quilting, refer to "Pulling up the
bobbin thread" on page B-22.
CAUTION
• Use a bobbin that has been correctly wound
with thread, otherwise the needle may break
or the thread tension will be incorrect.
• Before inserting or changing the bobbin, be
sure to turn off the machine, otherwise injuries
may occur if the "Start/Stop" button or any
other button is pressed and the machine starts
operating.
