Place the sewing machine on a stable, level surface. Ensure adequate lighting for your work area. If your machine is treadle-operated, ensure the treadle mechanism is free from obstructions.

To wind the bobbin, first release the balance wheel (D, Fig. 3) to disengage the sewing mechanism. This allows the bobbin winder to operate independently. Follow the specific threading path for bobbin winding as indicated in your machine's design. Once the bobbin is full, re-engage the balance wheel.

1. Placer trådspolen på spoleholderen.
2. Guide the thread through the upper tension discs.
3. Pass the thread through the take-up lever.
4. Tråd nålen forfra og bagpå.
