3. Operating Instructions
3.1 Opening a Can
- Position the Can Opener: Place the can opener flat on top of the can, ensuring the cutting wheel and gear are aligned with the can's rim.
- Start Operation: Press the single button on top of the can opener. The device will automatically grip the can and begin rotating, cutting along the side of the rim.
- Automatic Stop: The can opener will automatically stop once it has completed a full rotation around the can. If it does not stop automatically, press the button again and wait 2 seconds for it to halt.
- Remove the Lid: Once the cutting is complete, the can opener's magnet will hold the lid. Carefully lift the can opener away from the can. If the lid remains on the can, use the integrated lid lifter to gently pry it off.

3.2 Smooth Edge Cutting
The can opener cuts along the side of the can's rim, leaving a smooth, safe edge on both the can and the lid. This design minimizes the risk of injury from sharp edges.

3.3 Magnetic Lid Removal
After cutting, the can opener's integrated magnet securely holds the lid, preventing it from falling into the can's contents. For stubborn lids, use the small lever on the side of the opener to lift the lid away.

4. Maintenance and Care
4.1 Cleaning
To clean the can opener, wipe the exterior with a damp cloth. Do not immerse the device in water or wash it under running water, as this can damage the electronic components. Use a small brush or cloth to clean any food residue from the cutting wheel and gear after each use.
4.2 Storage
Store the can opener in a dry place, away from direct sunlight and extreme temperatures. Its compact size allows for easy storage in kitchen drawers or cabinets.
5. Troubleshooting
- Device does not start: Ensure the can opener is fully charged. If the battery is low, connect it to a USB-C charger.
- Can opener stops mid-operation: The battery might be low, or the can opener might be misaligned. Re-position the device and try again. If the issue persists, charge the battery.
- Lid is not completely cut: Ensure the can opener is properly seated on the can's rim. The device may require a second press of the button to complete the cut if it stopped prematurely.
- Lid falls into the can: The magnetic lid lifter may not have engaged properly. Ensure the can opener is lifted straight up after cutting. Use the integrated lid lifter if needed.
