Thread and Needle Chart
* 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 BLUE TIPPED needle.
The blue tipped needle effectively prevents
skipped stitches.
Changing Needles
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 screwdriver.
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.
