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.
