Frequently Asked Questions - JS-20 BROTHER
How do I thread the upper thread on the Brother JS-20?
Start by raising the presser foot and turning the handwheel until the needle is at its highest position. Place a spool on the spool pin and guide the thread through the thread guide, then down between the tension discs. Pull the thread through the take-up lever from right to left, then down to the needle clamp. Finally, thread the needle from front to back using the automatic needle threader if needed.
How do I wind the bobbin?
Place the thread spool on the pin and wrap the thread around the bobbin winder tension disc. Push the bobbin onto the bobbin winder spindle and push the spindle to the right. Hold the thread end and press the foot controller or speed control to wind. When full, the spindle will stop automatically; cut the thread and push the spindle back to the left.
How do I adjust stitch length and width?
Use the stitch length dial on the front of the machine. Numbers usually range from 0 to 4, where 0 is no feed and 4 is about 4 mm per stitch. For stitch width, turn the dial for zigzag or decorative stitches; a higher number gives a wider stitch. Always make a test seam on scrap fabric first.
The machine is skipping stitches. What should I do?
Skipped stitches are often caused by a dull, bent, or incorrectly inserted needle. Replace the needle with a new HAx1 (or 15x1) needle, ensuring the flat side faces the back. Also re-thread the upper thread and check the bobbin is wound evenly. Clean any lint from the feed dogs and the needle plate area.
How do I clean and oil the sewing machine?
Turn off and unplug the machine. Remove the needle plate and brush out lint and dust with a soft brush or lint brush. Use a small vacuum if available. Oil the hook area and any moving parts indicated in the manual with sewing machine oil. Do not over-oil, and wipe any excess. It's recommended to oil after every few hours of use or when the machine runs stiff.
What presser feet are included and how do I change them?
The JS-20 comes with a standard all-purpose foot, a zipper foot, a buttonhole foot, and a button sewing foot. To change the foot, raise the presser foot and press the release lever on the back of the foot holder. Slide the new foot into place and lower it until it clicks securely.
How do I make a buttonhole?
Set the stitch selector to the buttonhole position (usually one of the numbered patterns). Attach the buttonhole foot and mark the fabric for the buttonhole length. Lower the presser foot so the mark aligns with the dot on the foot. Pull the buttonhole lever down, hold the thread lightly, and let the machine sew the buttonhole automatically. Then cut the opening with a seam ripper.
The needle keeps breaking. Why?
Needle breakage commonly occurs when the needle is bent, the needle is incorrectly installed, or the thread tension is too tight. Check that the needle is straight and fully inserted with the flat side toward the back. Also ensure you are using the correct needle size for the fabric (e.g., 90/14 for medium fabrics). Avoid pulling the fabric while sewing, as this can bend the needle.
How do I sew different fabrics? What tension should I use?
For lightweight fabrics like silk or chiffon, use a fine needle (65/9) and set the tension lower (2-3). For medium fabrics like cotton, use a 75/11 or 90/14 needle and tension around 4. For heavy fabrics like denim, use a larger needle (100/16) and increase tension slightly. Always test on a scrap piece first. The tension dial typically ranges from 0 to 9, with 4 as the default.
Where can I find spare parts or accessories for the Brother JS-20?
Spare parts such as bobbins, needles, presser feet, and belts are available at authorized Brother dealers, online marketplaces, or directly from Brother's official website. Always order genuine Brother parts to ensure compatibility and performance. You can also check the manual for part numbers and local service centers.
