Which size of needle you can best use depends on the thickness of the fabric you use. With a thick fabric you should use a thick needle. The packaging of your needle states for which substances your needle is suitable.

There can be several causes for needle breakage:
— Not using the right needle for the right fabric
— The needle is set too low
— The fabric is not properly guided
— The bobbin case is not inserted correctly

Generally, a sewing needle lasts about 7 to 9 hours.

The Janome MyLock 644D is a versatile and efficient overlock sewing machine designed to deliver professional-quality finishes for a variety of fabrics. It features a 2, 3, or 4-thread serging capability, allowing users to choose the best stitch configuration for their projects. The machine boasts a differential feed mechanism, which can be adjusted to prevent stretching or puckering on different fabric types, ensuring smooth and even stitching. The MyLock 644D offers an adjustable cutting width ranging from 3.1mm to 7.3mm, providing flexibility for edge finishing. Its color-coded threading system simplifies setup, and the lay-in tension dials allow for precise tension control. The machine is equipped with a rolled hem changeover device, facilitating quick transitions to rolled hemming without needing to change the needle plate.

For ease of use, the MyLock 644D includes a retractable upper knife for safe threading and a lower looper threader to assist in threading the lower looper. The machine operates at a maximum speed of 1,300 stitches per minute, enhancing productivity for larger projects. The presser foot pressure is adjustable, making it adaptable for varying fabric thicknesses. A built-in thread cutter and a snap-on presser foot system further enhance convenience and efficiency. Designed with a sturdy metal frame, the Janome MyLock 644D ensures durability and stability during operation. This overlock machine is ideal for both beginners and experienced sewists, offering a combination of functionality, precision, and ease of use that makes it a reliable choice for achieving professional-looking garments and home décor projects.

To thread the Janome MyLock 644D, start by raising the presser foot to release the tension discs. Follow the color-coded threading guide on the machine. Begin with the upper looper, then the lower looper, followed by the right needle, and finally the left needle. Ensure each thread is securely placed in the tension discs and threading paths.

First, check the threading of the machine to ensure that each thread is properly seated in its tension disc. Adjust the tension dials according to the fabric type and the stitch you are using. Also, ensure that the needle is correctly inserted and not bent.

To prevent fabric puckering, adjust the differential feed settings. Increase the differential feed if the fabric is stretching, or decrease it if the fabric is gathering. Additionally, ensure the presser foot pressure is appropriate for the fabric being sewn.

Regular maintenance includes cleaning lint from the machine after each use, especially around the loopers and feed dogs. Oil the moving parts as per the instruction manual. Have the machine serviced professionally every 1-2 years depending on usage.

To change the needle, turn off the machine and unplug it. Use the needle change tool or a small screwdriver to loosen the needle clamp screw. Remove the old needle and insert the new one with the flat side facing the back. Tighten the needle clamp screw securely.

Unusual noises may indicate that the machine needs cleaning or oiling. Check for threads or lint caught in the loopers or feed dogs. If the noise persists, have the machine inspected by a professional technician.

It is recommended to use serger needles specifically designed for the Janome MyLock 644D, such as ELx705 needles, to ensure optimal performance and stitch quality.

The stitch length can be adjusted by turning the stitch length dial located on the right side of the machine. Turn the dial to increase or decrease the stitch length according to your sewing needs.

Check the condition of the blades. If they are dull or damaged, they may need sharpening or replacement. Ensure the blades are properly aligned and securely fastened.

To perform a rolled hem, remove the left needle and adjust the tension settings as indicated in the manual. Set the stitch length to a shorter setting and adjust the differential feed if necessary. Use a lightweight thread for best results.
