To thread the Janome HD9 Professional, begin by raising the presser foot and turning the handwheel to raise the needle to its highest position. Place the spool on the spool holder and guide the thread through the thread guide at the top. Follow the thread path, ensuring it goes through the tension discs and thread take-up lever. Finish by threading the needle from front to back.
If the machine skips stitches, first check if the needle is inserted correctly or is bent. Ensure you are using the correct needle and thread for your fabric. Re-thread the machine, making sure the thread is correctly seated in the tension discs.
To maintain the Janome HD9, regularly clean the bobbin area and feed dogs with a brush. Oil the machine according to the manual's recommendations. Avoid using compressed air as it may push lint further into the machine.
Thread bunching may be caused by incorrect threading, tension issues, or a bobbin incorrectly wound. Re-thread both the upper thread and the bobbin, and check the tension settings. Ensure the bobbin is inserted properly.
To adjust the tension, use the tension dial located on the machine. For thicker fabrics, increase the tension; for lighter fabrics, decrease it. Test on a scrap fabric to ensure the stitching is balanced.
For denim fabric, it is recommended to use a size 16/100 or 18/110 needle to ensure effective and smooth stitching without needle breakage.
A loud noise may indicate that the machine needs cleaning or oiling. Check for any trapped threads or lint in the bobbin area. Ensure that the needle is not bent and is correctly installed.
Yes, the Janome HD9 Professional can sew leather. Use a leather needle and consider using a walking foot to help move the leather smoothly through the machine. Adjust the tension according to the thickness of the leather.
To wind the bobbin, place an empty bobbin on the bobbin winder spindle. Guide the thread from the spool, through the bobbin winding guide, and wrap it around the bobbin a few times. Push the spindle to engage the winding mechanism and start the machine.
Needle breakage can be caused by incorrect needle size or type, incorrect threading, or sewing over pins. Ensure the needle is appropriate for the fabric and correctly installed. Avoid sewing over pins, and re-thread the machine if needed.
