Changing Needles

Raise the needle by turning the handwheel toward you and
lower the presser foot.
Loosen the needle clamp screw by turning it
counterclockwise.
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.
Caution:
Always make sure to turn the power switch off and disconnect
the machine from power supply before changing the needle.
* 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 Janome Blue Tipped needle.
The blue tipped needle effectively prevents skipped
stitches.
* When sewing very fine fabrics, sew over a piece of paper
to prevent seam puckering.
