MACHINE MAINTENANCE An overlock requires more frequent maintenance than a conventional sewing machine for two reasons: • A lot of lint is produced when the cutters are cutting the fabric. • An overlock runs at a very high speed and needs to be oiled frequently to lubricate the internal working parts. Storage When the machine is not in use, be sure to keep it unplugged. Store the machine, so it is not exposed to direct sunlight or humidity. Servicing If you have any questions regarding service and/or operation, contact our Customer Care department. Cleaning the Upper Cutter Area Turn off the main power switch and unplug the machine. Open the front cover. With a forward brushing movement, use the lint brush to remove any lint. Note: You may use a vacuum cleaner to clean the upper knife area or feed teeth. Cleaning the Feed Teeth A Turn off the main power switch and unplug the machine. Deactivate the stitch finger by setting it in "R" position (A). Open the side and front covers. Remove the needle(s) and the presser foot. Remove the set screw (B) with the large screw driver. Remove the needle plate. Use the lint brush to remove any lint from around the feed teeth (C). Place the stitch plate over the feed teeth, making sure the C tab of the stitch plate (D) is inserted under the edge of the cover (E). The hole in the stitch plate (F) should align with the knob on the machine (G). Replace and tighten the set screw. Attach the needle(s) and the presser foot. Close the side and front covers.
