Changing Needles; Thread And Needle Chart - Janome QS2250 Manual De Instrucciones

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.
* 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 thread 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 BLUE TIPPED needle.
The blue tipped needle effectively prevents skipped
stitches.
* When sewing very fine fabrics, sew over a piece of
paper to prevent yarn distortion.
