5. Operating Instructions
5.1 Hot Air Gun Operation
- Power On: Flip the main power switch to ON. The LCD screen will illuminate.
- Activate Hot Air Gun: Press the independent start switch for the hot air gun.
- Adjust Temperature: Use the "TEMP ▲" and "TEMP ▼" buttons to set the desired hot air temperature. Long press for rapid adjustment, short press for fine tuning.
- Adjust Airflow: Rotate the "AIR" knob to set the desired air volume (1% to 100%).
- Use Quick-Set Keys: Press one of the "1", "2", or "3" buttons to recall a saved temperature and airflow preset. To save a preset, adjust to desired settings, then long-press the desired quick-set button until it beeps.
- Nozzle Replacement: The hot air gun uses pluggable nozzles. Allow the gun to cool, then carefully remove the current nozzle and insert the desired one.

- Auto-Sleep Function: When the hot air gun is placed on its stand, the touch sensor will activate the auto-sleep function, reducing temperature and airflow to save energy and prolong heater life. It will resume operation when picked up.
5.2 Soldering Iron Operation
- Activate Soldering Iron: Press the independent start switch for the soldering iron.
- Adjust Temperature: Use the "TEMP ▲" and "TEMP ▼" buttons to set the desired soldering iron temperature. Long press for rapid adjustment, short press for fine tuning.
- Use Quick-Set Keys: Similar to the hot air gun, use buttons "1", "2", or "3" to recall or save temperature presets for the soldering iron.
- Tip Replacement: The soldering iron uses an integrated heating core design for quick heating and temperature recovery. To replace the tip, ensure the iron is cool and disconnected from power. Unscrew the retaining collar and carefully pull out the old tip, then insert the new one and secure the collar.

6. Maintenance
- Cleaning Tips/Nozzles: Regularly clean soldering iron tips with a damp sponge or brass wool. Clean hot air nozzles as needed to ensure unobstructed airflow.
- Unit Cleaning: Wipe the main unit and handles with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Brushless Vortex Fan: The hot air gun features a brushless vortex fan for gentle and even airflow, contributing to longer lifespan and lower noise. Keep the air intake clear of dust and debris.

- Cable Inspection: Periodically check all cables for signs of wear or damage. Replace if necessary.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on | Power cord not connected, main switch off, blown fuse. | Check power cord connection, ensure main switch is ON. Check and replace fuse if necessary (refer to specifications for fuse type). |
| Hot air gun not heating/no airflow | Hot air gun switch off, temperature/airflow set too low, heater element failure. | Ensure hot air gun switch is ON. Increase temperature/airflow settings. If problem persists, contact support. |
| Soldering iron not heating | Soldering iron switch off, temperature set too low, heating element/tip failure. | Ensure soldering iron switch is ON. Increase temperature setting. Check if tip is properly installed. If problem persists, contact support. |
| Incorrect voltage operation (e.g., 110V unit on 220V supply) | Unit connected to incompatible power supply. | The unit is designed for specific voltages (110V or 220V). Ensure your unit matches your local power supply. Using the wrong voltage can damage the unit. |
