Safety Information
Please read and understand all safety warnings and instructions before operating this tool. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage.
- Ventilation: Always operate the hot knife in a well-ventilated area. Cutting foam with heat can release fumes that may be harmful if inhaled. Consider using a fume hood or working outdoors.
- Hot Surfaces: The blade and surrounding components become extremely hot during operation. Avoid contact with skin and flammable materials. Allow the tool to cool completely before storing.
- Overheat Protection: The tool features an overheat protection system (displaying "OTT"). If activated, allow the tool to cool down. It will automatically restore operation within 30 seconds. This system protects the tool from damage.
- Blade Installation: Ensure blades are securely fastened with the included wrench. Loose blades can lead to poor performance and potential hazards.
- Power Source: Use only with a 110V-127V power supply.
- Storage: Store the tool and accessories in a dry, safe place, out of reach of children.

Operating Instructions
Operating the Preciva Hot Knife Foam Cutter is straightforward. Always ensure you are in a well-ventilated area.
- Connect Power: Plug the tool into a standard 110V-127V power outlet.
- Adjust Temperature: Use the temperature control roller to select the desired heat setting. The digital display will show the current temperature. The temperature scale rises from top to bottom. Start with lower settings and gradually increase as needed for your material.
- Temperature Range: 200-600°C (392°F-1112°F)
- Temperature Conversion: Display value × 9 + 212 = °F
- Heat Up: Press the switch to activate heating. The tool heats up rapidly, reaching 200°C (392°F) in approximately 6 seconds.
- Cutting: Once the blade is hot, gently guide it through the material. Apply steady, even pressure. The hot knife provides clean cuts and automatically seals edges, preventing fraying.
- Overheat Protection: If the display shows "OTT", the overheat protection is active. Release the switch and allow the tool to cool. Operation will resume automatically within 30 seconds.

Maintenance
Proper maintenance ensures the longevity and performance of your hot knife.
- Blade Cleaning: After use, and once the blade has cooled sufficiently but is still warm, use the included wire brush to clean any residue from the blade. This prevents buildup and maintains cutting efficiency.
- Storage: Ensure the tool is completely cool and clean before storing it in its case or a safe, dry location.
- Inspection: Periodically inspect the power cord and blades for any signs of damage or wear. Replace damaged blades immediately.
Refer to Step 6 in Figure 3 for a visual guide on cleaning the blade.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not heat up. | Not plugged in; loose blade connection; power issue. | Check power connection. Ensure blade screws are tightened securely. Verify power outlet is functional. |
| "OTT" displayed on screen. | Overheat protection activated. | Release the switch and allow the tool to cool down. It will reset automatically within 30 seconds. |
| Cuts are rough or uneven. | Incorrect temperature setting; dull or dirty blade; improper technique. | Adjust temperature (increase for harder materials, decrease for softer). Clean the blade with the wire brush. Use a steady hand and a guide for straight cuts. |
| Blade twists or bends during cutting. | High temperature setting; inherent blade characteristic (especially long blades). | Reduce temperature. Ensure blade is securely fastened. Consider using a shorter blade for more stability or a guide for long cuts. |
