6. Operating Instructions

1. Power On: Press the ON/OFF button on the control unit to power on the device. The LED display will illuminate.
2. Set Temperature: Use the UP and DOWN arrow buttons to adjust the desired temperature. The temperature range is 100°C to 480°C. Press SET to confirm the temperature. The unit will rapidly heat to the set temperature.
3. Adjust Airflow: While the unit is heating or operating, you can adjust the airflow using the UP and DOWN buttons (after pressing SET to cycle to airflow adjustment, if applicable, or if the unit has dedicated airflow buttons). The maximum airflow is 120 liters per minute.
4. Operation: Once the desired temperature is reached, you can begin your soldering or desoldering task. Always hold the hot air gun handle firmly and direct the hot air carefully.
5. Automatic Cool-down: When the hot air gun handle is placed back into its stand, the unit will automatically detect this and initiate a cool-down process. The fan will continue to run until the temperature drops below 70°C, at which point it will automatically stop. This feature extends the life of the heating element.
6. Power Off: Press the ON/OFF button to turn off the device. If the hot air gun is still hot, it will enter cool-down mode before fully shutting down.

Note: The unit features microcomputer control for rapid heating and stable temperature output (stability of ±2°C). The high-quality heating element ensures a long service life.

7. Maintenance

• Cleaning: Ensure the device is unplugged and completely cool before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Nozzle Care: Keep the nozzles clean and free from debris. Replace damaged or clogged nozzles.
• Heating Element Replacement: If the heating element's resistance value becomes incorrect or it fails, it can be replaced. Refer to the included spare heating element (Image 6). This procedure should only be performed by qualified personnel or with extreme care, ensuring the device is unplugged and cool.
