1. Introduction
This manual provides detailed instructions for the safe and effective use of your Silverflo 857D+ Hot Air Rework Station. Please read this manual thoroughly before operation and retain it for future reference. This device is designed for precision soldering and desoldering tasks, offering reliable performance for various electronic components.
2. Important Safety Warnings
- Always ensure the air outlet is clear and free from any blockages.
- Nozzles should only be installed or removed when the steel pipe and nozzle are cool to prevent burns. Do not use excessive force or tools that could damage the nozzle or pipe.
- Maintain a minimum distance of 2mm between the hot air gun's air outlet and the object being worked on.
- Never direct the hot air stream towards your face or body parts to avoid severe burn injuries.
- During initial use, the hot air gun may emit a small amount of white fumes. This is normal and will dissipate shortly.
- The steel tube of the hot air gun may show a slight bronze discoloration after use. This is a normal result of the high-temperature testing and calibration processes during manufacturing and does not affect performance.

5. Setup
5.1 Unpacking and Initial Inspection
Carefully remove all components from the packaging. Inspect the unit for any visible damage. Ensure all accessories are present.
5.2 Critical Pre-Operation Step: Remove Locking Bolt
Before using the machine, you MUST remove the red-marked locking bolt located at the bottom of the station. Failure to remove this bolt will cause serious damage to the internal blower during operation.
Note: The locking bolt is essential for securing the blower during transportation. If you need to transport the station again, ensure this bolt is re-installed to prevent damage.
5.3 Assembly
- Place the rework station on a stable, heat-resistant surface.
- Install the hot air gun holder onto the left side of the station.
- Select the appropriate nozzle for your task. For general use, larger diameter nozzles are recommended. When using smaller nozzles, refer to the operation section for specific guidance.
- Connect the station's power cord to a suitable electrical outlet (120V US or 220V EU depending on your model).
6. Operation
- **Power On**: Turn on the power switch. The hot air gun will enter standby mode.
- **Set Temperature and Air Volume**: Use the "TEMP CONTROL" knob to set the desired temperature (100°C - 450°C) and the "AIR CONTROL" knob to adjust the air volume. The LED digital display will show the current temperature.
- **Begin Operation**: Pick up the hot air gun from its holder. The gun will automatically enter normal operating status. The operation indicator light will stay ON while heating up and blink rapidly once the set temperature is stabilized.
- **Using Smaller Nozzles**: If using nozzles smaller than the standard ones, it is crucial to set the air volume to maximum and use a relatively lower temperature. Perform the operation in the shortest possible duration to prevent damage to the hot air gun.
- **Standby Mode**: When you finish your work, place the hot air gun back into its holder. The power to the heating element will automatically turn OFF, and the operation indicator light will turn OFF. The gun will continue to blow air without heat to cool down the heating element.
- **Power Off**: Once the temperature cools to below 100°C (212°F), the station will enter standby mode. You can then turn off the power switch. If the station will not be used for an extended period, disconnect the power cord.
7. Maintenance
- Regularly check the air outlet for any dust or debris and ensure it remains unobstructed.
- Clean the exterior of the station with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ensure the hot air gun and nozzles are cool before handling or cleaning.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows "S-E" | Faulty sensor module in the hot air gun. | Replace the heating element (which includes the sensor module). |
| Operation indicator is ON, but hot air gun is not heating up | Faulty heating element. | Replace the heating element. |
| After replacing heating element, unit still malfunctions | Incorrect wiring of the heating element. | Ensure the connecting wires are reconnected in their original order and color. Incorrect connections can cause further issues. |
| Slight noise during operation | Normal operation of the Roots-type blower. | No action required; this is normal for this model. |
9. User Tips
- For optimal performance and longevity, ensure proper ventilation around the unit during operation.
- The machine generally performs well for its intended purpose. Familiarize yourself with temperature and airflow settings for different tasks.
