Threading & Bobbin Winding

Correct threading is essential for proper stitch formation.

Winding the Bobbin:

1. Place the spool of thread on the spool pin.
2. Guide the thread through the bobbin winding tension disc on the top.
3. Place an empty bobbin on the winder shaft, push to the right.
4. Hold the thread end, press the foot pedal to wind. Stop when full.
5. Cut the thread and push the winder shaft back to the left.

Threading the Upper Thread:

1. Raise the presser foot and needle to highest position.
2. Follow the numbered path: from spool pin, through thread guides, down to tension discs, up and around the take-up lever, down to the needle.
3. Use the built-in needle threader: Lower the lever, hook the thread, and pull back through the needle eye.

WARNING! Ensure the presser foot is raised when threading to open the tension discs.

Care & Maintenance

Regular cleaning and lubrication ensure long-lasting performance.

1. Cleaning: Unplug the machine. Remove the needle plate and bobbin case. Use the small brush to remove lint and dust from the feed dogs, bobbin area, and hook race. Replace parts.
2. Oiling: Apply one drop of sewing machine oil to the hook race and other moving parts as indicated in the manual. Wipe away excess oil.
3. Needle Replacement: Replace the needle after every 8-10 hours of sewing or with each new project. A dull or bent needle can cause skipped stitches and fabric damage.
4. Storage: Cover the machine when not in use to prevent dust accumulation. Store in a dry place.

CAUTION! Always unplug the machine before cleaning or maintenance. Use only recommended sewing machine oil.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Machine does not run	Not plugged in / Power switch off	Check power cord connection and wall outlet. Ensure foot pedal is connected.
Thread bunching underneath (bird nesting)	Incorrect bobbin threading / Upper thread not in tension discs	Re-thread the bobbin and upper thread, ensuring presser foot is raised during threading.
Skipped stitches	Dull/bent needle / Wrong needle for fabric	Replace the needle with a new, correct type (e.g., ballpoint for knits).
Uneven or loose stitches	Incorrect tension setting / Thread quality	Adjust the thread tension dial. Use good quality thread of the same weight on top and bobbin.
Needle breaks	Wrong needle size / Pulling fabric / Bent needle	Use correct needle size for fabric. Do not pull fabric; let machine feed it. Ensure needle is inserted correctly and straight.
Fabric not feeding	Feed dogs lowered / Stitch length set to 0	Raise the feed dogs using the drop feed lever. Adjust stitch length dial to a setting above 0.
Unusual noise	Lint buildup / Lack of oil / Loose parts	Clean and oil the machine as per maintenance instructions. Check for and tighten any loose screws.
