4. Instrukcja obsługi

Once the new bobbin case is installed, follow these steps to prepare it for sewing.

1. Insert the Bobbin: Place a wound bobbin into the new bobbin case. Ensure the thread unwinds in the correct direction (usually counter-clockwise when viewed from the top, but refer to your sewing machine's manual for specific guidance).
2. Thread the Bobbin Case: Guide the bobbin thread through the tension spring slot on the side of the bobbin case. Pull the thread gently until it slides under the tension spring and emerges from the small opening.

3. Close the Bobbin Cover: Once the bobbin case is correctly threaded and seated, close the bobbin cover plate.
4. Bring Up the Bobbin Thread: Hold the upper thread lightly, turn the handwheel towards you to lower and raise the needle once. The needle will catch the bobbin thread, bringing a loop up through the needle plate. Pull both threads to the back of the machine before starting to sew.

5. Konserwacja

Regular maintenance of your bobbin case will ensure consistent sewing performance.

• Czyszczenie: Periodically remove the bobbin case and use a small brush or lint remover to clean out any lint, dust, or thread fragments that may accumulate around the tension spring or inside the case. Accumulation can affect thread tension.
• Kontrola: Regularly inspect the bobbin case for any signs of wear, nicks, or burrs, especially on the edges where the thread passes. Such imperfections can snag the thread and cause breakage or skipped stitches.
• Regulacja napięcia: The bobbin case has a small screw for tension adjustment. Only adjust this screw if you are experienced and confident in doing so, as incorrect tension can lead to sewing problems. Small adjustments can be made with a precision screwdriver.
