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.
