Read the model-specific requirements with each answer before choosing parts.

Needle

Needle insertion

Bobbin

Bobbin insertion

  • Switch the sewing machine off (0) before threading the bobbin or making needle-area adjustments.
  • Follow the complete cited procedure; no inferred material or dimensional equivalence.

Place the bobbin counterclockwise; hold it lightly while drawing thread through notch, follow the groove up and around the top, left then down; pull right to cut. Replace cover with left tabs in needle-plate holes and right side clicked down.

Still to confirm

An unanswered question does not mean a part is incompatible. We have not confirmed enough information to recommend it.

Needle — System: No single universal needle system established; fabric-specific chart is not generalized. Full recorded limit & conditions →

Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.

Next evidence targets

  • Complete illustrated task review, broader specifications and exact compatible items require additional accepted evidence; the cited subset is not a complete machine reference

These are research questions, not claims that the missing relationship exists.
