• Changing Needle
Raise the needle by turning the handwheel
toward you and lower the presser foot.
Loosen the needle clamp screw by turning it
counter-clockwise. Remove the needle from the
clamp.
Insert the new needle into the needle clamp with
the flat side away from you.
When inserting the needle into the clamp, push it up
as far as it will go and tighten the clamp screw firmly
with the screwdriver.
* Check your needles frequently for barbed or
blunted
points. Snags and runs in knits, fine silks and
silk-like fabrics are permanent and are almost
always caused by a damaged needle.

* In general, fine threads and needles are used for
sewing thin fabrics, and thicker threads and
needles are used for sewing heavy fabrics.
Always test thread and needle size on a small piece
of fabric which will be used for actual sewing.
* Use the same thread for needle and bobbin.
* When sewing stretch, very fine fabrics and
synthetics, use a stretch needle.
The stretch needle effectively prevents
skipped stitches.
* When sewing very fine fabrics, sew over a piece
of paper to prevent distortion.
