Push the spool cap onto the spool pin as far

original position.
 CAUTION
• Be sure to thread the machine properly. 
Improper threading can cause the thread to 
tangle and break the needle, leading to injury.
• When using accessories not included with this 
machine, attach the accessory to the machine 
after threading the machine. 
Memo
• The automatic threading function can be 
used with sewing machine needles 75/11 
through 100/16.
• Thread such as transparent nylon monofila-
ment thread and thread with a thickness of 
130/20 or thicker cannot be used with the 
automatic threading function. 
• The automatic threading function cannot be 
used with the wing needle or the twin nee-
dle.
• If the automatic threading function cannot be 
used, see “Threading Manually” on page 31.

Note
If you try to thread the needle automatically 
without raising the needle, the thread may not 
thread correctly.
 CAUTION
• If the thread spool and/or spool cap are set 
incorrectly, the thread may tangle on the spool 
pin and cause the needle to break.
• Use the spool cap (large, medium, or small) 
that is closest in size to the thread spool. If a 
spool cap smaller than the thread spool is 
used, the thread may become caught in the slit 
on the end of the spool and cause the needle 
to break.
