4. Setup and Blade Replacement

4.1 Power Connection

Connect the device to a power source using the provided USB-C to USB-C data cable and 30W charging head. The input voltage should be 12-15V. The device does not have a built-in battery and requires continuous power during operation.

4.2 Blade Replacement

Follow these steps to safely replace the blade:

1. Before replacing the blade, ensure that the power has been cut off and the blade and body have completely cooled down. This prevents scratches and cuts.
2. Use the hex wrench to loosen the fastening screw and remove the old blade.
3. Insert the new blade into the slot of the blade fixing clamp, paying attention to the correct direction of the blade edge (facing outward). Ensure the blade is inserted to the bottom of the blade fixing clamp.
4. Use the hex wrench to tighten the fastening screws again completely.

5. Operating Instructions

5.1 Safety Lock

The device features a humanized safety lock design for secure operation:

• Normally illuminated: The safety lock function is disabled.
• Blinking: The security lock feature is activated.

Activate the safety lock function when not in use to prevent accidental activation. When cutting, toggle the safety lock function to immediately stop cutting and protect your safety.

5.2 Adjusting Cutting Modes

The Awgem KH1 offers 5 levels of adjustable cutting options to suit different materials and tasks:

• Level 1: Gentle Mode
• Level 2/3: Standard Mode
• Level 4/5: Power Mode

Select the appropriate mode based on the material's hardness and desired cutting precision. The device features industrial-grade automatic frequency tracking for stable and precise cutting.

5.3 Material Compatibility

The Awgem KH1 is capable of cutting and polishing a wide range of materials, including but not limited to:

• Paper/Cardboard
• Wooden Board/Chip
• Carbon Fiber Board
• Acrylic
• Plastics (such as ABS, PE, PVC)
• Leather
• Handmade/Toy materials (e.g., 3D resin, foam)
• Circuit Board
• Gypsum
• Composite materials (such as FRP, carbon fiber panels)

It is not suitable for cutting most metal materials, soft rubber, sponges, and other materials that absorb vibrations.

6. Maintenance

• Cleaning: After each use, ensure the device is powered off and cooled. Gently wipe the blade and device body with a soft, dry cloth to remove any debris or residue.
• Blade Care: Regularly inspect blades for wear and tear. Replace dull or damaged blades promptly to maintain optimal cutting performance and prevent damage to the device or material.
• Storage: Store the ultrasonic cutter and its accessories in the provided storage box in a dry, cool place, away from direct sunlight and moisture. Ensure the safety lock is engaged before storing.
• Avoid Contact: To extend the service life of the blades, avoid contact between the blade and non-food materials such as metal parts.

7. Troubleshooting (FAQ)

Q: What is the difference between KH1 ultrasonic cutting knife and traditional cutting knife?

A: Ultrasonic cutting knives use high-frequency vibration for cutting, without the need for traditional sharp blades. It is suitable for cutting soft, elastic, or viscous materials, while traditional cutting knives rely on physical pressure and sharp edges.

Q: What is the principle of ultrasonic cutting knife and what materials is it suitable for cutting?

A: The principle is 40KHz high-frequency vibration, causing fatigue in the molecular structure of the material, thereby achieving cutting with almost no wear and heat generation. It can cut a variety of materials including paper products, plastic materials (such as ABS, PE), composite materials (such as FRP, carbon fiber panels), 3D prints, and textiles. It is not effective on most fabrics, soft rubber, sponges, and cannot cut metal.

Q: How to extend the service life of ultrasonic cutting knives?

A: Avoiding contact between the blade and non-food materials such as metal parts, proper use, and good maintenance habits can significantly extend the service life of the blade.

Q: Is the ultrasonic cutting knife completely silent?

A: Under normal operation, the vibration frequency of the blade exceeds the range of human hearing, making it almost silent. However, at certain specific cutting angles, some subtle high-frequency noise may be generated.

Q: Does the product come with a built-in battery?

A: The product does not include batteries and needs to be used with a 45W adapter and Type-C data cable.

Q: Is the product waterproof?

A: This product does not have waterproof function, especially the Type-C interface at the rear, which must avoid any contact or infiltration of moisture.

Q: Will the product generate heat during use, and is there an overheat protection mechanism?

A: Due to the frictional heat generated by ultrasonic transducers and blades during high-frequency vibration operations, this product is designed with a temperature protection mechanism. When the internal temperature of the equipment exceeds 70 degrees, a temperature control protocol will be triggered. At this point, it is necessary to allow the product to cool naturally until the temperature drops, and then restart it to ensure safety and continued use.

9. User Tips

• For optimal performance and to avoid continuous cutting stuttering, ensure the device is adequately powered by a 45W adapter.
• When cutting delicate materials, start with a lower gear (Gentle Mode) and gradually increase if needed.
• Always ensure the blade is securely fastened before operation to prevent accidents and ensure precise cuts.
• If you experience poor cutting quality or low cutting efficiency, check for tool wear, improper settings, or if the equipment needs maintenance/calibration.
• The device is lightweight and portable, making it easy to handle for extended periods without fatigue.
