To thread the machine, start by raising the presser foot and turning the handwheel to raise the needle. Follow the threading path as indicated in the user manual, ensuring the thread passes through the tension discs and the take-up lever. Finally, thread the needle from front to back.
If the machine is skipping stitches, check that the needle is correctly inserted and not bent or dull. Ensure you are using the correct needle size and type for your fabric. Re-thread the machine to ensure proper threading.
To adjust the tension, use the tension dial located on the front of the machine. Turn it clockwise to increase tension and counterclockwise to decrease it. Test on a scrap piece of fabric to ensure proper tension settings.
Regular maintenance tasks include cleaning the machine of lint and dust, oiling the designated lubrication points as per the manual, and checking the needle and thread guides for wear. It's also important to have the machine serviced by a professional annually.
A loud noise can be caused by a lack of lubrication or a jam. First, check for any thread or fabric caught in the bobbin area. Clean and oil the machine according to the manual's guidelines. If noise persists, consult a technician.
To change the needle, turn off the machine and hold the old needle while loosening the needle clamp screw. Remove the needle and insert a new one, ensuring the flat side is facing the correct direction. Tighten the needle clamp screw securely.
Ensure the presser foot is down and the feed dogs are engaged. Check for any obstruction in the feed dog area. Adjust the presser foot pressure if necessary, and ensure the stitch length is set appropriately for the fabric type.
Thread breaking can be caused by incorrect threading, tension settings, or a damaged needle. Re-thread the machine carefully, check the tension settings, and replace the needle if it appears damaged or worn.
To clean the machine, use a soft brush to remove lint and dust, especially around the feed dogs and bobbin case. Avoid using compressed air, which can push debris further inside. Wipe the exterior with a soft, damp cloth.
Adjust the needle type and size based on the fabric, and set the tension and stitch length accordingly. For heavier fabrics, increase the presser foot pressure and use a thicker needle. Always test on a fabric scrap before starting your project.
