To thread the machine, start by placing the spool on the spool pin, guide the thread through the thread guide, down through the tension discs, and up through the take-up lever. Finally, thread the needle from front to back.
Check that the needle is correctly inserted and not bent. Ensure proper threading and that the tension is properly adjusted. It’s also important to use the correct needle and thread type for the fabric.
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 tension. Test on a scrap piece of fabric to ensure proper tension.
Regular maintenance includes cleaning the bobbin area, oiling the machine as per the manual, checking and replacing needles, and ensuring that all moving parts are free from lint and debris.
Turn off the machine, loosen the needle clamp screw, remove the old needle, and insert a new one with the flat side facing the back. Tighten the needle clamp screw securely.
Check the power cord connection and ensure the outlet is functional. Inspect the power switch and confirm that it is turned on. If the problem persists, consult a technician.
Ensure that the fabric is properly fed through the machine. Check thread tension, and inspect the needle for damage or incorrect size. Re-thread the machine if necessary.
Use a high-quality sewing machine oil as specified in the user manual. Avoid using household oils as they may damage the machine.
Place the bobbin in the bobbin case, ensuring the thread unwinds in the correct direction. Pull the thread through the slot and guide it under the tension spring before placing the bobbin case into the shuttle.
Stop the machine immediately and check for any jammed fabric or thread. Inspect for loose screws and ensure that all parts are properly lubricated. If the noise persists, consult a professional technician.
