Needle information This overlock uses a flat shank industrial needle that eliminates the possibility of inserting the needle backwards. Do not attempt to use a standard household sewing machine needle of any size or type in this overlock. Use INSPIRA™ needle EL x 705 sizes 14/90 and 12/80, supplied with this machine. Changing the needles Turn off the main power switch and unplug the machine. • Turn the handwheel toward you until the needles are at the highest position. • Place a thick piece of fabric under the presser foot. Lower the needles halfway into the fabric. • Loosen, but do not remove the needle clamp screw with the allen key while you are holding the needles. Note: When inserting needles into the A and/or B needle clamps it is necessary to loosen the needle clamp screws for both A and B. • Remove the selected needle. • Hold the new needle with the flat surface to the back. • Insert the needle into the needle clamp as far as it will go. Note: We recommend using the hole in the needle threader to hold the needle. • Securely tighten the needle clamp screw using the allen key. Note: Do not over-tighten the screw as this may cause the needle clamp to be damaged. Movable upper cutter Disengaging, position B Turn off the main power switch and unplug the machine.
