Zwischenstand
2026-10-31:
Adam und Jakob haben versucht die Maschine ordentlich in Betrieb zu nehmen. Aber nach neuem Einfädeln haben die Fäden sich nicht mehr richtig zusammengefunden. Offenbar hat der Untergreifer den Oberfaden nicht mehr getroffen. Wir haben deshalb den Winkel des Untergreifers verändert. Dadurch wird der Oberfaden jetzt gefangen, aber beim weiteren Testen hat sich dadurch die Nadel verbogen. Die Vermutung, ist dass wir den Winkel des Untergreifers nochmal ordentlich anpassen müssen. Zusätzlich kann geprüft ob die Nadelstange an der richtigen Höhe ist.
Untergreifer gebrochen: Der Untergreifer ist abgebrochen. Wir müssen den Untergreifer ersetzen oder die Maschine ist kaputt.
- Ersatz teil(e) gefunden und ist bestellet - Adam

Threading
For a complete 4-thread setup, thread the machine in this order:

- lower looper — yellow
- right needle — green
- left needle — blue
Refer to the manual (page 10, if you need to thread from scratch, page 17, if you need to change once specific thread). A visual explanation can be found on YouTube.
Basic use
- Extend the thread stand fully and fit the waste container.
- Check the threading, needle position, knife position and selected settings.
- Make a test seam on a scrap of the same fabric. Adjust one setting at a time using the tables in the manual.
- Lower the presser foot and guide the fabric edge towards the knife. Let the feed dogs move the fabric.
- At the end of the seam, continue sewing until a thread chain of approximately 5 cm has formed.
- Switch off the machine and remove fabric scraps and loose threads.
Cleaning and maintenance
Unplug the machine before cleaning or maintenance.
- Regularly remove lint and fabric scraps from the looper and knife area with the supplied brush.
- Wipe the exterior with a slightly damp cloth.
- Lubricate only the points shown in the manual and use sewing-machine oil only.
- Stop using the machine and report the problem if a needle or knife is damaged, the machine jams or it no longer cuts cleanly.
