 Setup and Adjustment

• Choose the right needle and thread: Select the appropriate needle and thread based on the thickness and type of material. For heavy materials like canvas or denim, use stronger needles and threads.
• Adjust sewing modes: Select the sewing mode (e.g., straight stitch, zigzag stitch) according to the requirements of your work, ensuring that the machine settings are suitable.
• Set stitch length and needle position: Adjust the stitch length and needle position according to the sewing needs, adapting to different stitching requirements.

2. Operating Tips

• Handling fabric: Avoid pulling the fabric too tight or too loose during sewing. Guide the fabric smoothly to maintain even tension throughout the stitching process.
• Starting sewing: Ensure the fabric is correctly aligned in front of the needle before starting the machine. Gently push the fabric and avoid pulling it to prevent machine jams or needle breakage.
• Sewing speed: Adjust the sewing speed based on the complexity of the work and the thickness of the fabric. For complex tasks, a slower speed may be needed for precision.
• Needle replacement: Regularly check the needle for sharpness and replace dull or bent needles to avoid stitching issues or fabric damage.

3. Sewing Techniques

• Sewing edges: Use edge guides or stitch guides when sewing fabric edges to maintain even stitching and straight lines.
• Reverse stitching: Perform reverse stitching (backstitching) at the beginning and end of seams to lock the thread and prevent it from unraveling.
• Trimming thread ends: Trim excess thread after sewing to keep the seams clean and tidy.

4. Fabric and Machine Coordination

• Use appropriate presser feet: Choose the correct presser foot based on the type of fabric. Different presser foot designs can help handle various fabric types and sewing needs.
• Cleaning and maintenance: Clean the needle, feed dogs, and other machine parts after each use to remove fabric remnants or dust.

5. Safety Precautions

• Power management: Ensure a secure power connection before use, and avoid touching the machine when plugging or unplugging it.
• Avoid touching moving parts: Keep fingers away from the needle and sewing area during operation to prevent accidents.
