5. Operating Instructions
This section details the process of coiling wire and cutting jump rings.
5.1 Coiling Wire
- Prepare Wire: Select the desired jewelry wire. Ensure the end of the wire is straight for easy insertion.
- Insert Wire: Feed the end of the wire into the small hole at the tip of the chosen mandrel.
- Begin Coiling: While holding the wire taut, slowly turn the handle of the machine. The wire will begin to coil around the mandrel. Maintain consistent tension for even coils.
- Continue Coiling: Continue turning the handle until the desired length of coiled wire is achieved.
- Remove Coiled Wire: Once coiling is complete, loosen the chuck and carefully slide the coiled wire off the mandrel.

5.2 Cutting Jump Rings
After coiling the wire, use the cutting tool to create individual jump rings.
- Position Coiled Wire: Place the coiled wire into the cutting guide slot on the base unit. Ensure the coil sits snugly within the guide.
- Prepare Cutting Tool: Insert the cutting blade into the flexible shaft holder.
- Cut Rings: Carefully guide the cutting blade along the coiled wire in the slot. Apply steady pressure and move the blade smoothly to cut individual jump rings.
- Collect Rings: Once cut, the jump rings will be separated. Collect them for your jewelry projects.

- Mandrel Care: Keep mandrels clean and free of scratches. Store them in their designated slots to prevent damage.
- Blade Sharpening/Replacement: If the cutting blade becomes dull, sharpen it or replace it with a new one to ensure clean cuts.
