■ Attaching the extra spool pin
Insert the extra spool pin onto the end of the bobbin
winder shaft. Install the second thread spool onto
the extra spool pin.

thread the twin needle. Instead, thread the
twin needle by hand, from front to back.
Using the needle threader may damage the
machine (see page 24).

CAUTION
●
After adjusting the stitch width, slowly
turn the handwheel toward you
(counterclockwise) and check that the
needle does not touch the presser foot. If
the needle hits the presser foot, the
needle may bend or break.
●
When using the twin needle, make sure
the stitch width is not set above "2.5"
since this may cause the needle to hit the
needle plate and break.
