Changing Needle

q Needle clamp screw
w Needle clamp
z Turn off the power switch.
Raise the needle to its highest position by
turning the handwheel counterclockwise,
toward you, and lowering the presser foot.
Loosen the needle clamp screw q by
turning it counterclockwise. Remove the
needle from the needle clamp w.
x Insert a new needle into the needle clamp
with the flat side to the rear. When inserting
the needle into the needle clamp w, push it
up as far as it goes. Tighten the needle clamp
screw q firmly by turning it clockwise.
c To see if the needle is good, place the flat
side of the needle onto something flat (e.g
needle plate or glass).
The gap between the needle and the flat
surface should be consistent. Never use a
bent or blunt needle.
A damaged needle can cause permanent
snags or runs in knits, fine silks and silk-like
fabrics.
* 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.
