1. Start by turning the handwheel (A) toward you
to raise the needle (B) and the thread take up
lever (C). You should be able to see the take up
lever.
2. Raise the presser foot lifter. This is
necessary in order for the machine to be
threaded correctly.
3. Place the thread spool and spool cap onto the
spool holder.
4. Draw thread from the spool through the upper
thread guide at the top of the machine. Hold the
thread with both hands and pull it into the pre-
tension guide.
5. (A) Bring the thread down the right channel,
around the U-turn, and up the left channel.
(B) At the top of the left channel, hook the
thread from back to front through the slotted eye
of the thread take-up lever. If the thread does
not pass into the eye of the take-up lever, the
machine will jam. After threading the take-up
lever, bring the thread downward again.
(C) Pass the thread behind the metal thread
guide and then down to the needle.
6. If you want to thread the needle manually,
thread it from front to back. Pull about 6-8
inches of thread to the back beyond the needle
eye. Alternatively, you can use the automatic
needle threader to thread the eye of the needle.
