CAUTION
Do not touch any of the moving parts or press any objects against the machine while winding the lower thread.
Injury or damage to the sewing machine may result.
1. Place the bobbin onto the bobbin winder shaft (1).
2. Thread the thread as shown in the illustration, wind the
thread around the bobbin several times, and then press
the bobbin presser arm (2).
3. Turn on the power switch.
4. Depress the foot switch to the 2nd step.
(If using a two-pedal foot switch, lower the work clamp
before depressing the start switch.
The feed mechanism will move to the home position.

6. Release the TENSION WIND key (3) after the machine
starts operating, and keep depressing the foot switch
until the lower thread stops being wound onto the
bobbin.
(If you release the foot switch before winding is
complete, and then depress it again while pressing the
TENSION/ WIND key (3), winding will start again.)
7. Once winding of the set amount of lower thread (80 -
90% of the bobbin capacity) is completed, the bobbin
presser arm (2) will return automatically.
8. Remove the bobbin, hook the thread onto the knife (4),
and then pull the bobbin in the direction of the arrow to
cut the thread.
Adjusting the bobbin winding amount
