Maintenance (Cleaning the thread paths of the upper threads)
If dust or lint has accumulated in the thread guides or tension unit in the paths of the upper threads, the thread may break while embroidery is being sewn. Periodically clean the thread paths.
Clean the thread guide plates for both the upper thread guides and the middle thread guides.
