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 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.
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.
