6. Operating Instructions

6.1. Hot Air Gun Operation

1. Power On: Flip the power switch to the 'ON' position. The LCD display will illuminate.
2. Adjust Temperature: Press the 'SET' button to select temperature adjustment mode. Use the 'Up' (+) and 'Down' (-) buttons to set the desired temperature between 100°C and 480°C. Pressing and holding the buttons will adjust the temperature continuously. The newly set temperature will be saved after 3 seconds and retained for the next power-on.
3. Adjust Airflow: Press the 'SET' button again to select air volume adjustment mode. Use the 'Up' (+) and 'Down' (-) buttons to adjust the airflow. The maximum airflow is 150 liters per minute.
4. Nozzle Replacement: To replace a nozzle, ensure the unit is cool. Carefully remove the current nozzle and attach the desired one. The product comes with four types of nozzles (large, medium, small, and micro) to suit various applications.
5. Automatic Stop Feature: The hot air gun features an automatic rotation stop function when the temperature drops below 70°C, enhancing safety and extending component life.
6. Power Off: Flip the power switch to the 'OFF' position. Allow the unit to cool down completely before storing.

6.2. Soldering Iron Operation (Model 908U)

The 908U soldering iron operates with a voltage of AC 220-240V or AC 100-130V and has a power output of 80W. Its temperature range is 180°C to 500°C (356°F to 932°F) with a stability of ±5°C.

1. Power On: Connect the soldering iron to the power supply. The LCD display will show the current temperature.
2. Adjust Temperature:
   • Press the (+) button once to increase the temperature by 1°C. Press and hold to increase continuously.
   • Press the (-) button once to decrease the temperature by 1°C. Press and hold to decrease continuously.
   The newly set temperature will be saved after 3 seconds and will be maintained for the next power-on.
3. Temperature Indicator: When the symbol (F) or (C) blinks, it indicates that the heating element has not yet reached the set temperature.
4. Usage: Once the desired temperature is reached, the soldering iron is ready for use. Always use appropriate soldering techniques and safety precautions.
5. Power Off: Disconnect the soldering iron from the power supply when finished. Allow it to cool down completely in its stand before storage.

7. Maintenance

• Cleaning: Regularly clean the hot air gun nozzles and soldering iron tips to prevent residue buildup. Use a damp cloth for the main unit after ensuring it is unplugged and cool.
• Soldering Tip Care: Keep soldering iron tips tinned to prevent oxidation. Use the steel ball cleaner to remove excess solder.
• Storage: Store the device and its accessories in a dry, dust-free environment, away from direct sunlight and extreme temperatures. Ensure all components are cool before storage.
• Heating Element Replacement: The heat gun heating element is replaceable. Refer to the included spare part for replacement if necessary.

8. Troubleshooting

• Device Not Powering On: Check the power connection and ensure the power switch is in the 'ON' position. Verify the power outlet is functional.
• Temperature Not Reaching Set Value (F/C Blinking): This indicates the heating element is still working to reach the set temperature. Allow more time. If it persists, ensure the nozzle is clear and the heating element is functioning correctly.
• Weak Airflow: Check for any obstructions in the nozzle or air intake vents. Ensure the air volume setting is appropriately adjusted.
• Soldering Iron Not Heating: Ensure the iron is properly connected and the temperature is set above ambient. Check the heating element if the issue persists.
