Introduction
Thank you for purchasing the Silverflo 858D-II Hot Air Rework Station. This manual provides detailed instructions for the safe and efficient operation, maintenance, and troubleshooting of your device. Please read this manual carefully before use and keep it for future reference.
For additional information, you may refer to the official user manual PDF: Silverflo 858D-II User Manual (PDF).
Safety Precautions
- Always keep the hot air gun's air outlet clear and free of blockages.
- Install hot air nozzles ONLY when the hot air gun's steel pipe and the nozzle have cooled. Install the nozzle correctly; do not use brute force, pull the edge of the nozzle with tweezers, or over-tighten screws.
- Select the appropriate nozzle based on your operation requirement (temperatures may vary when using nozzles in different diameters). When using nozzles smaller than the stock nozzles, you MUST use the maximum air volume with a relatively lower temperature setting. Complete this operation in the shortest duration possible to avoid damaging the hot air gun.
- Keep a minimum distance of 2mm between the subject and the hot air gun's air outlet.
- Do NOT allow the hot air to come in direct contact with facial parts and beware of the danger of burn injuries.
- Upon first use, the hot air gun may emit white fumes, which will dissipate shortly.
- The station's hot air gun and soldering iron use high-strength stainless steel tubes. The steel tube may exhibit a slightly bronze color when new due to quality control testing; this is normal.
Applications
The Silverflo 858D-II Hot Air Rework Station is designed for a wide range of electronic repair tasks, including:
- Rework and soldering operations on various components such as SOIC, CHIP, QFP, PLCC, BGA, and SMD. It is particularly well-suited for rework operations on in-line sockets.
- Heat shrinking.
- Drying.
- Paint removal.
- Conformal coating removal.
- Defrosting.
- Pre-heating.
- Glue soldering.
Product Overview
The Silverflo 858D-II Hot Air Rework Station features a compact design with intuitive controls for temperature and air volume. Below is an illustration of the main components and their functions.
Main Components:
- Temperature Display (Hot Air)
- Temperature Increase Button
- Temperature Decrease Button
- Air Volume Adjustment Knob
- Power Switch
Setup Instructions
- Position the Rework Station: Place the rework station on a stable, heat-resistant surface. Attach the hot air gun holder to the right side of the main unit.
- Place Hot Air Gun: Rest the hot air gun securely in its holder when not in use.
- Install Nozzle: Select the required nozzle for your task. It is recommended to use larger diameter nozzles when possible. Ensure the nozzle is installed correctly and securely.
- Connect Power: Connect the station's power cord to a suitable electrical outlet.
Operating Instructions
- Power On: Turn ON the hot air rework station's power switch. The temperature display will show "---", indicating the rework station is in standby mode.
- Set Temperature: Press the Temperature Increase (+) or Decrease (-) buttons to set the desired temperature.
- Begin Operation: Pick up the hot air gun from its holder. The hot air gun will enter the standard operation status, and its operation indicator (the dot located at the bottom-right corner of the hot air display) will turn ON. The indicator stays ON when the hot air gun is heating, blinks rapidly when the temperature stabilizes, and turns OFF when the hot air gun is cooling.
- Adjust Air Volume: Use the Air Volume Adjustment Knob to set the desired air volume.
- Stabilization: Begin operation once the hot air temperature has stabilized. The rapidly blinking indicator light indicates temperature stabilization; the PID program is tracking and compensating the actual hot air gun temperature in milliseconds. The hot air gun is now in a high-stability and high-precision thermostatic state.
- Sleep Mode: When you place the hot air gun back into its holder, the system automatically cuts off power to the heating element, and the operation indicator light turns OFF. The heating element then starts to cool. When the temperature cools below 100°C/212°F, the display will show "---".
- Power Off: Turn OFF the rework station. If not in use for an extended period, disconnect the station's power plug.
Digital Temperature Calibration
Temperature discrepancies may occur due to environmental changes or replacement of components. This function allows you to correct temperature deviations, improving work efficiency and prolonging the heating element's lifespan.
- When the hot air gun's temperature has stabilized, press both the Temperature Increase (+) and Decrease (-) buttons simultaneously for approximately 2 seconds. The display will alternate between the set temperature and "CAL".
- Press the Temperature Increase (+) or Decrease (-) buttons to input the measured hot air temperature value.
- Once the setting is complete, press both the Temperature Increase (+) and Decrease (-) buttons simultaneously to confirm. The system will automatically calibrate the temperature and exit the calibration interface.
Maintenance
- Keep Air Outlet Clear: Ensure the hot air gun's air outlet is always clear and free of any blockages.
- Nozzle Installation: Only install or remove nozzles when the hot air gun's steel pipe and the nozzle are cool. Avoid using excessive force or tools that could damage the nozzle or the hot air gun.
- Nozzle Selection: When using smaller nozzles than the standard ones, set the air volume to maximum and use a lower temperature for a shorter duration to prevent damage.
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). |
| Temperature discrepancies after heating element replacement. | Incorrect wiring during replacement. | Ensure the original connecting order and colors of the wires are followed precisely. Do NOT connect incorrectly. |

User Tips
- Always ensure the hot air gun is securely placed in its holder when not actively in use to activate the sleep mode and prolong the heating element's life.
- For delicate components, start with lower temperature and air flow settings and gradually increase as needed to prevent damage.
- Regularly check the air outlet for any dust or debris to maintain optimal performance and prevent overheating.
