Changing Needle; Thread And Needle Chart - Baby Lock BL9 Instruction And Reference Manual

Changing Needle

CAUTION:
Turn off the power switch when changing a 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 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.
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.

* 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.
