Janome 7312 Magnolia Instruction Book

To thread the Janome 7312 Magnolia, start by raising the presser foot and turning the handwheel to raise the needle. Place the spool on the spool pin and draw the thread through the guide, tension discs, and take-up lever. Then, thread the needle from front to back.
If the machine is skipping stitches, try re-threading the machine, ensuring the needle is inserted correctly, and using the correct needle type and size for the fabric. Also, check if the needle is bent or dull and replace it if necessary.
Regularly clean the machine by removing lint and dust from the bobbin area and feed dogs using a small brush. Oil the machine as per the manufacturer’s instructions and have it serviced annually by a professional.
For heavy fabrics, use a size 16/100 or 18/110 needle. Make sure to use a needle specifically designed for heavy-duty sewing to ensure smooth stitching.
To adjust the tension, use the tension dial located on the front of the machine. Increase the tension for thicker fabrics and decrease it for lighter ones. Test on a scrap fabric to find the perfect setting.
If the bobbin thread is bunching, re-thread the upper thread, ensuring it is in the tension disc correctly. Also, check if the bobbin is wound evenly and inserted properly in the bobbin case.
Ensure the machine is threaded correctly, use the appropriate needle and thread for the fabric, and adjust the tension settings as needed. Regular cleaning and maintenance can also improve stitch quality.
Unusual noises may indicate that the machine needs cleaning or oiling. Check for any thread or lint caught in the bobbin area and ensure all parts are properly tightened. If the noise persists, consult a professional technician.
To sew buttonholes, use the buttonhole foot and select the buttonhole stitch on the machine. Mark the fabric where the buttonhole is needed, place the fabric under the foot, and sew the buttonhole following the machine’s instructions.
If the fabric isn't feeding smoothly, check that the presser foot is down and the feed dogs are engaged. Adjust the presser foot pressure and ensure the fabric is properly aligned. Clean the feed dogs to remove any lint or debris.
