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.
*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.
