Main controls are located on the front and right side of the machine.
Stitch Selection Dial: Turn to select one of the 23 stitch patterns (symbols and numbers indicated). Stitch Length Dial: Controls stitch length (0-4). Higher numbers for longer stitches.

Tip: Practice on scrap fabric first. Always test stitch length, width, and tension on a fabric scrap similar to your project.
Regular cleaning ensures optimal performance and longevity.
CAUTION! Always unplug the machine before cleaning or performing any maintenance. Never use compressed air to clean, as it can force lint deeper into the mechanism.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Thread bunching underneath (bird's nest) | Incorrect bobbin threading; upper thread not in tension discs | Re-thread the bobbin and upper thread completely, ensuring presser foot is raised during threading. |
| Skipped stitches | Dull/bent needle; incorrect needle type; needle not fully inserted | Replace needle with a new, correct type (e.g., Universal). Ensure it is pushed fully up and tightened. |
| Machine does not run | Not plugged in; foot control unplugged; machine not turned on | Check all power connections. Ensure the power switch (if present) is in the "on" position. |
| Uneven or puckered seams | Incorrect thread tension; poor quality thread | Adjust tension dial (usually set to 4-5). Use good quality, all-purpose thread. |
| Needle breaks | Wrong needle size for fabric; bent needle; pulling fabric | Use a heavier needle for thick fabrics. Let the feed dogs move the fabric; do not pull. Ensure needle is straight. |
| Difficulty turning handwheel | Thread jam in bobbin area; machine not oiled | Unplug, remove needle plate and bobbin case to clear any tangled thread. Oil the machine as per manual. |
Reset: For persistent issues, unplug the machine, wait 60 seconds, and re-plug. Ensure all settings are returned to default (straight stitch, medium length/width).
