Mantenimiento
Regular maintenance ensures the longevity and smooth operation of your machine.
1. Limpieza
After each use, clean lint and dust from the bobbin area, feed dogs, and tension discs using a small brush. Periodically remove the needle plate for a more thorough cleaning of the feed dog area.
2. Lubricación
Refer to the machine's lubrication points (usually marked with red dots or arrows). Apply a few drops of high-quality sewing machine oil to these points regularly, especially after extended use. Wipe off any excess oil.
3. Reemplazo de aguja
Replace needles frequently, especially when sewing different types of fabric or if the needle shows signs of bending or dullness. A dull needle can cause skipped stitches and fabric damage.
