2.3 Power Connection
- Connect the hot air gun and soldering iron handles to their respective ports on the main unit.
- Plug the main unit's power cord into a suitable electrical outlet (ensure voltage compatibility).
3. Operating Instructions
3.1 Power On/Off
- Flip the main power switch on the front panel to turn the unit on or off.
3.2 Hot Air Gun Operation
- **Temperature Adjustment**: Use the 'TEMP' up/down buttons in the 'SMD REWORK' section to set the desired hot air temperature.
- **Air Volume Adjustment**: Use the knob in the 'SMD REWORK' section to adjust the air volume.
- **Hot/Cold Air Switch**: The hot air gun handle features a separate button to switch between hot and cold air modes. Pressing this button will cycle between heating and cooling the air.
- **Preset Channels**: The hot air gun has three preset channels (CH1, CH2, CH3) for quick recall of frequently used temperature and air volume settings. Use the 'CH' button to cycle through these presets.

3.3 Soldering Iron Operation
- **Temperature Adjustment**: Use the 'TEMP' up/down buttons in the 'SOLDERING' section to set the desired soldering temperature. The soldering iron handle also has a separate button for quick temperature adjustments.
- **Preset Channels**: Similar to the hot air gun, the soldering iron also has three preset channels (CH1, CH2, CH3) for quick recall of temperature settings. Use the 'CH' button to cycle through these presets.

4. Maintenance
4.1 Sleep Mode and Automatic Stand-by
- The soldering iron features a sleep mode that activates when the iron is placed in its holder. This helps prolong tip life and enhances safety.
- An automatic shutdown feature will power off the unit approximately 5 minutes after entering sleep mode, further improving safety and energy efficiency.

4.2 General Cleaning and Care
- Regularly clean soldering tips with a damp sponge or brass wool to remove oxidation and solder residue.
- Ensure hot air gun nozzles are free from debris.
- Keep the main unit clean and free from dust. Use a soft, dry cloth for cleaning.
- Store the unit in a dry, safe place when not in use.
5. Troubleshooting
5.1 Common Issues and Solutions
- **No Power**: Check the power cord connection and the main power switch. Ensure the power outlet is functional.
- **Hot Air Gun Not Heating**: Verify the temperature setting and ensure the hot/cold air switch on the handle is in the hot air position. Check for any error codes on the display.
- **Soldering Iron Not Heating**: Verify the temperature setting. Ensure the tip is properly installed and making good contact.
- **Inaccurate Temperature Reading**: Perform a digital temperature calibration as described in section 3.4.
- **Weak Airflow**: Check for any obstructions in the hot air gun nozzle or hose. Ensure the air volume knob is set correctly.
5.2 Replacement Parts

8. User Tips
- When working with delicate components, always start with lower temperature and airflow settings and gradually increase them as needed to prevent damage.
- Utilize the preset channels (CH1, CH2, CH3) to save your most common temperature and airflow settings for quick and efficient workflow.
- Regularly check the condition of your soldering iron tips and hot air nozzles. Worn or dirty tips can significantly impact soldering quality.
- If you notice any issues with the handles (C210/C245), such as inconsistent heating or connection problems, consider contacting support for replacement options to ensure optimal performance and safety.
