2. Safety Instructions
Your KFD power supply is engineered with multiple safety features to protect both the device and the user. Adhering to these guidelines is crucial for safe operation:
- Over Voltage Protection (OVP): Prevents damage from excessive input voltage.
- Over Current Protection (OCP): Safeguards against damage from excessive output current.
- Short Circuit Protection (SCP): Automatically shuts down in case of a short circuit to prevent hazards.
- Over Temperature Protection: Monitors and regulates internal temperature to prevent overheating.
- Over Load Protection: Protects against excessive power draw.
- Over Charger Protection: Ensures safe charging cycles.
Always ensure the power supply is used in a well-ventilated area and avoid covering it during operation. Do not expose the adapter to water or extreme temperatures.

9. Troubleshooting
If you encounter issues with your KFD power adapter, consider the following common troubleshooting steps:
- No Power/Not Charging:
- Ensure the power adapter is securely plugged into both the wall outlet and the vacuum cleaner.
- Try plugging the adapter into a different wall outlet to rule out a faulty outlet.
- Verify that the vacuum cleaner's charging port is clean and free of debris.
- Confirm that the vacuum cleaner itself is functioning correctly (e.g., battery is not completely depleted or faulty).
- Adapter Overheating:
- Ensure the adapter is in a well-ventilated area and not covered.
- Disconnect the adapter and allow it to cool down before reconnecting. If overheating persists, discontinue use and contact support.
- Incorrect Fit:
- Double-check the model compatibility list. The adapter may not be suitable for all vacuum cleaner models, even if the voltage is similar.
- Ensure the DC connector size matches your device's port exactly.
