g Fully insert the spool for the upper thread
onto the spool pin
Slide the spool onto the pin so that the spool is
horizontal and the thread unwinds to the front
at the bottom.
CAUTION
● If the spool is not positioned so that the
thread unwinds correctly, the thread may
become tangled around the spool pin and the
thread or needle may break.
● If the spool cap that is used is smaller than the
spool, the thread may catch, for example, on
the notch in the spool, or the needle may
break.

h Slide the spool cap onto the spool pin.
Memo
● When sewing with fine, cross-wound
thread, use the small spool cap, and leave a
small space between the cap and the spool.

● When using thread that winds off quickly,
such as transparent nylon thread or metallic
thread, place the spool net over the spool
before placing the spool of thread onto the
spool pin.
If the spool net is too long, fold it to fit the
size of the spool.
When the spool net is used, the tension of
the upper thread will slightly increase. Be
sure to check the thread tension. For details,
refer to "Adjusting the thread tension"
(page 47).
