- Assemble Hot Air Gun Holder: Secure the hot air gun holder to the side of the main unit or place it on the workbench.
- Connect Soldering Iron: Plug the soldering iron handle connector into the 'SOLDERING STATION' port on the front of the main unit. Secure it by tightening the threaded collar.
- Connect Hot Air Gun: Plug the hot air gun handle connector into the 'REWORK STATION' port on the front of the main unit.
- Power Connection: Connect the power cord to the back of the main unit and then to a suitable grounded power outlet.

Operating Instructions
Power On/Off
Flip the main power switch located on the front panel to 'ON' to power on the station. Flip to 'OFF' to power off.
Soldering Iron Operation
- Temperature Adjustment: Use the '+' and '-' buttons next to the 'SOLDERING STATION' display to set the desired temperature. The LED display will show the current temperature.
- Rapid Heating: The T12 soldering iron features rapid heating, quickly reaching the set temperature for efficient work.
- Auto Sleep Mode (10-Minute): If the soldering iron detects no usage or movement for longer than 10 minutes, it will automatically enter sleep mode. This prevents tip oxidation, extends tip lifespan, saves energy, and protects the environment. To wake up the soldering iron, simply pick it up or press any button.


Hot Air Gun Operation
- Temperature Adjustment: Use the '+' and '-' buttons next to the 'REWORK STATION' display to set the desired hot air temperature.
- Air Volume Adjustment: Use the rotary knob to adjust the air volume output.
- Automatic Start/Standby: The hot air gun automatically starts when picked up from its holder and enters standby mode when placed back.
Digital Temperature Calibration
Both the hot air gun and soldering iron support digital temperature calibration to ensure precise temperature readings and improve work efficiency. This process typically involves:
- Simultaneously pressing the temperature '+' and '-' buttons on the respective station.
- Measuring the current actual temperature of the tool using an external, calibrated thermometer.
- Adjusting the displayed temperature on the station to match the measured temperature.

Maintenance
Soldering Iron Tip Care
- Regularly clean the soldering iron tip using the provided metal cleaning ball or cleaning sponge. This helps prevent oxidation and ensures efficient heat transfer.
- Always tin the tip with a small amount of solder after cleaning and before storing to protect it from oxidation.
- Replace tips when they become excessively worn or corroded.

Hot Air Gun Maintenance
- The hot air gun features a brushless fan for long service life and smooth air delivery. No specific user maintenance is typically required for the fan itself.
- Keep the air nozzles clean and free from obstructions.

General Cleaning
- Wipe the main unit and handles with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ensure the unit is unplugged and cool before cleaning.
Troubleshooting
- No Power: Check the power cord connection and ensure the main power switch is in the 'ON' position. Verify the power outlet is functional.
- Soldering Iron Not Heating: Ensure the soldering iron is properly connected to the station. Check if it's in auto-sleep mode (pick it up to reactivate). Verify the temperature setting.
- Hot Air Gun Not Working: Ensure the hot air gun is properly connected and picked up from its holder. Check the temperature and air volume settings.
- Inaccurate Temperature Reading: Perform a digital temperature calibration as described in the Operating Instructions section.
