Automatic Needle Threader
¤
Pull about 6-8” of thread to the back beyond the eye of the needle. This will help prevent the needle
from becoming unthreaded when you start to sew.
⚠ For safety, turn off the power before using the automatic needle threader.
1. Lower the presser foot lifter. Raise the
needle to its highest position by turning
the handwheel toward you. If you turn the
handwheel backward, the machine will jam
when you start to sew.
2. Pass thread around thread guide.
3. Press lever down as far as it will go. The
threader automatically swings to the threading
position.
4. Pass the thread in front of the needle and under
the hook.
5. To cut the excess thread, take thread tail and
gently slip it over the thread cutter located to the
right of the needle.
6. Release the lever & the thread tail at the same
time, this will form a loop at the back of the
needle.
7. Pull the thread through the needle eye. While
holding the thread, raise the presser foot lifter
and pull the thread under the foot toward the
back.
