CAUTION
Do not touch any of the moving parts or press any objects against the machine while winding the lower thread, as this may
result in personal injury or damage to the machine.
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 second step. The feed
mechanism will move to the home position.
5. Check that the needle is not touching the work clamp/button
clamp, and then while pressing the ENTER key (3), depress
the foot switch to the second step.
6. Release the ENTER 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 ENTER 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
Loosen the screw (5) and move the bobbin presser (6).
If the thread winds onto the bobbin unevenly
Loosen the nut (7) and move the bobbin winder tension
assembly (8) up and down to adjust.
