- Grip: Hold the nipper firmly by its ergonomic handles. The green handles are designed for a comfortable and secure grip.
- Positioning: Place the wire or component to be cut between the double-edged jaws. Ensure the material is positioned as close to the pivot point as possible for maximum leverage and a clean cut.
- Cutting: Apply steady, firm pressure to the handles to close the jaws and cut through the material. Avoid twisting the nipper during the cut.
- Cutting Capacity: The nipper is designed to cut copper wire up to 3.2 mm (0.1 inch) in diameter. Do not attempt to cut materials exceeding this capacity or harder materials like steel wire, as this can damage the blades.

- Cleaning: After each use, wipe the nipper clean with a dry cloth to remove any debris, dust, or moisture.
- Lubrication: Periodically apply a small amount of light machine oil to the pivot point to ensure smooth operation and prevent rust.
- Storage: Store the nipper in a dry, clean environment, away from corrosive chemicals and extreme temperatures. A tool roll or box is recommended to protect the blades.
- Blade Inspection: Regularly inspect the cutting edges for nicks, dullness, or damage. While the blades are durable, excessive force or cutting inappropriate materials can cause damage.
