7. Operating Instructions
7.1 General Operation

Figure 2: The 898D station ready for operation.
After connecting the unit to power, turn on the main power switch. The digital displays will illuminate.
7.2 Hot Air Rework Station Operation
- Turn on the SMD Rework Station Power Switch. The hot air display will show the current temperature.
- Press the Function Key (ENTER) until the hot air temperature display is selected (it may flash or indicate selection).
- Use the Temperature Adjustment Keys (Up/Down) to set the desired hot air temperature. The unit will quickly heat up to the set temperature.
- Adjust the Air Volume Adjustment Knob to control the airflow rate.
- When the hot air gun is placed in its holder, it will automatically enter standby mode and cool down. Picking it up will resume operation.

7.3 Soldering Station Operation
- Turn on the Soldering Station Power Switch. The soldering iron display will show the current temperature.
- Press the Function Key (ENTER) until the soldering iron temperature display is selected.
- Use the Temperature Adjustment Keys (Up/Down) to set the desired soldering iron temperature. The iron will heat up to the set temperature.
- Always clean the soldering iron tip with the damp sponge before and after use to ensure optimal performance and longevity.
7.4 One-Key Shift Function

Figure 4: Using the one-key shift to adjust temperature.
The Function Key (ENTER) allows for a quick shift between adjusting the hot air temperature and the soldering iron temperature. Simply press this key to toggle between the two modes, then use the Up/Down keys to adjust the temperature for the selected tool.
7.5 Temperature Calibration
If the displayed temperature differs significantly from a known accurate temperature measurement (e.g., using a thermometer designed for soldering tips), you can calibrate the unit:
- Ensure the unit is powered on and at a stable operating temperature.
- Press and hold the Function Key (ENTER) for a few seconds until the display enters calibration mode (the displayed temperature might flash or show a specific calibration indicator).
- Use the Temperature Adjustment Keys (Up/Down) to adjust the displayed temperature to match your external temperature measurement.
- Press the Function Key (ENTER) again to save the calibration and exit the mode.
8. Maintenance
- Cleaning: Regularly clean the unit's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Soldering Tip Care: Keep the soldering iron tip clean by wiping it on a damp sponge or brass wool. Tin the tip with solder after each use to prevent oxidation. Replace tips when they become excessively worn or corroded.
- Hot Air Nozzles: Ensure hot air nozzles are free from obstructions. Clean them if necessary after the unit has cooled down.
- Storage: Store the unit in a dry, dust-free environment when not in use.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on | No power supply; Power cord loose; Unit switch off | Check power outlet; Ensure power cord is securely connected; Turn on unit switches |
