THREAD NEEDLEFABRIC
*Synthetic threads are
recommended for
ordinary overlocking.
Polyester thread, for
example, is very useful for
different types of fabric.
NOTE:Keep in mind that
the lower and upper
loopers will use about twice
the amount of thread as the
needles. When purchasing
thread for sewing,
therefore, especially if it is
an unusual colour, you
should buy sufficient for
your requirements.
CHANGING NEEDLE
Raise needle bar to its highest point by turning hand wheel
towards you, but leave presser foot down. Loosen needle
clamp screw to remove the needle, and place new
needle with Flat Side Away From You, into the needle bar as
far as it will go, and tighten screw.
