The Sigma 161 is known as a "zigzadora robusta" (robust zig-zag machine). The manual typically includes:

: Always ensure the needle is at its highest point before threading. Follow the diagram in the manual to route the thread through the tension discs and take-up lever.

: For your safety, always turn the main switch to "O" (off) or unplug the machine when changing needles or performing maintenance. Manual Sigma Modelo 161 Pdf - Google Docs 🎁 Manual Sigma Modelo 161 Pdf - Google Drive. Google Docs Manual Sigma 161 - mimaquina.es
