1. Turn off the power switch and unplug the unit.
2. Allow the current nib to cool down completely. This may take several minutes.
3. Using the provided small screwdriver, carefully loosen the two screws holding the nib in place.
4. Use the tweezers to gently remove the old nib.
5. Select the desired new nib and insert its two prongs into the corresponding holes on the pen.
6. Tighten the two screws firmly to secure the new nib. Do not overtighten.

5.3 Pyrography Techniques

Experimentation is key to mastering pyrography. Always practice on scrap wood before working on your final project.

• Long Strokes: For consistent lines and shading, use smooth, continuous strokes. Avoid drawing too fast, as this can lead to faded color. Drawing too slowly can result in overly dark or burnt areas. Aim for consistent speed and pressure.
• Shading: Use a lower temperature or lighter pressure for subtle shading. For darker shades, increase temperature or apply more pressure, moving the pen slowly.
• Detailing: Utilize finer nibs and precise movements for intricate details and textures.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your wood burning kit.

• Cleaning Nibs: After each use, once the nib has cooled, gently clean any carbon buildup using a fine wire brush or sandpaper. This helps maintain consistent heat transfer and prevents uneven burning.
• Storage: Store unused nibs in the provided wire nib collector to keep them organized and prevent loss. Store the main unit and pen in a dry, safe place away from dust and moisture.
• Unit Cleaning: Wipe the main unit with a soft, dry cloth. Do not use liquid cleaners or immerse the unit in water.

7. Troubleshooting

If you encounter any issues with your YIHUA 939D-V Wood Burning Kit, refer to the following common problems and solutions:

• No Heat from Nib:
  • Ensure the power switch is in the 'ON' position.
  • Check that the power cord is securely plugged into a working outlet.
  • Verify that the wood burning pen is correctly connected and tightened to the main unit.
  • Confirm that a temperature is set on the digital display.
• Inconsistent or Faint Burn:
  • Increase the temperature setting on the main unit.
  • Ensure the nib is clean and free of carbon buildup.
  • Apply consistent pressure and maintain a steady speed while burning.
  • Check if the nib is securely fastened; loose screws can affect heat transfer.
• Nibs Not Holding Securely:
  • Ensure the two screws on the pen are tightened firmly after inserting the nib.
