3. Needle Types and Usage

The needle size indicates its thickness and suitability for different fabric types. A lower number signifies a finer needle, while a higher number indicates a thicker, stronger needle.

Included Needle Sizes:

• Size 11 (HAx1SP): Ideal for lightweight to medium-weight knit fabrics, such as jersey, interlock, and some stretch wovens. The ball point tip pushes fabric fibers aside rather than piercing them, preventing snags and runs.
• Size 14 (HAx1SP): Suitable for medium-weight knit fabrics, including fleece, heavier jerseys, and some stable knits. It offers increased strength for fabrics that require a slightly more robust needle without damaging the fibers.

4. Setup: Needle Installation

Proper needle installation is crucial for optimal serger performance and to prevent damage to your machine or fabric. Always ensure your serger is turned off and unplugged before changing needles.

General Installation Steps:

1. Power Off: Turn off your serger and unplug it from the power outlet.
2. Raise Needles: Turn the handwheel towards you to raise the needles to their highest position.
3. Loosen Screw: Locate the needle clamp screw(s) and loosen it with the screwdriver provided with your serger.
4. Remove Old Needle: Carefully pull the old needle(s) straight down and out. Dispose of old needles safely.
5. Insert New Needle: Insert the new Janome serger needle(s) into the needle clamp, ensuring the flat side of the needle shank faces the back of the machine. Push the needle(s) up as far as it will go.
6. Tighten Screw: Tighten the needle clamp screw(s) firmly to secure the needle(s) in place. Do not overtighten.
7. Thread Machine: Re-thread your serger according to your machine's instruction manual.

Important: Always consult your specific Janome serger machine's instruction manual for detailed, model-specific needle installation procedures.

5. Operating: Sewing Tips

To achieve the best results with your Janome serger needles, consider the following tips:

• Match Needle to Fabric: Always use the correct needle size and type for your fabric. Using a needle that is too large can create holes, while a needle that is too small can break or cause skipped stitches.
• Test on Scraps: Before sewing your main project, always test your stitch settings and needle choice on a scrap piece of the same fabric.
• Regular Replacement: Needles dull over time. Replace your serger needles after approximately 8-10 hours of sewing or at the start of a new project to ensure clean stitches and prevent fabric damage.
• Proper Threading: Ensure your serger is correctly threaded according to your machine's manual. Incorrect threading can lead to tension issues and skipped stitches.

6. Maintenance

Proper maintenance of your needles ensures longevity and consistent sewing quality.

• Storage: Store unused needles in their original packaging or a designated needle case to protect them from damage and keep them organized.
• Inspection: Before each use, inspect needles for any signs of bending, burrs, or dullness. A damaged needle can snag fabric or break during sewing.
• Disposal: Dispose of broken or dull needles safely in a sharps container or by wrapping them securely before discarding to prevent injury.

7. Troubleshooting

If you encounter issues while sewing, the needle might be a contributing factor. Here are some common problems and potential solutions:

• Skipped Stitches:
  • Ensure the correct needle type (ball point for knits) and size is used for the fabric.
  • Check if the needle is inserted correctly and fully seated.
  • Replace the needle; it might be bent or dull.
• Broken Needles:
  • Verify the needle is the correct size for the fabric thickness.
  • Ensure the needle is inserted correctly and tightened securely.
  • Avoid pulling or pushing fabric forcefully while sewing.
• Fabric Snagging or Damage:
  • Replace the needle immediately; it likely has a burr or is dull.
  • Confirm you are using a ball point needle for knit fabrics.
