4-3. Winding the lower thread

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 set screw (7) and move the bobbin wider tension
assembly (8) up and down to adjust.
* For case A, move the bobbin winder tension assembly (8)

down, and for case B, move it upward.
