* 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 the 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.
A stretch needle effectively prevents
skipped stitches.
Changing Needles
To Check the Needle
Place the flat side of the needle on something
flat (needle plate, glass etc.). The clearance
between the needle and flat surface should be
consistent. Never use a bent or blunt needle.
CAUTION:
When changing needles, turn OFF the
power switch.
Raise the needle by turning the handwheel
toward you and lower the presser foot.
z
Loosen the needle clamp screw by turning
it counterclockwise.
Remove the needle from the clamp.
x
Insert the new needle into the 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 screw
driver.
