CAUTION

Do not touch or place anything against any of the moving parts while winding the lower thread, otherwise
personal injury or damage to the machine may result.

1. Place the bobbin all the way onto the shaft.
2. Thread the thread as shown in the illustration at left,

wind the thread around the bobbin several times in the
direction of the arrow, and then press the bobbin
presser (1).

3. Turn on the power switch.

(The POWER indicator on the operation panel will
illuminate.)

4. Check that the needle is not touching the presser foot,

and then while pressing the STEP BACK switch (2),
depress the foot switch (3) to start the machine. Keep
depressing the foot switch (3) until the lower thread
stops being wound onto the bobbin.
Release the STEP BACK switch (2) after the machine
starts operating.
If you release the foot switch before winding is com-
pleted, depress it once more while pressing and hold-
ing the STEP BACK switch (2).

5. The bobbin presser (1) will automatically return to its

original position after a set amount of thread (80 - 90%
of the bobbin capacity) has been wound on.

6. Release the foot switch (3).
7. 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.

8. To wind more thread onto the bobbin, loosen the set

screw (5) and pull the bobbin presser (1) outward.

<< If the thread winds onto the bobbin unevenly >>

If the thread winds onto the bobbin unevenly, loosen
the nut (1) and turn the bobbin winder thread tension
stud (2) to adjust.
