• Disconnection: To disconnect, first unplug the adapter from the wall outlet, then remove the connector from the vacuum cleaner.

5. Maintenance

Proper maintenance ensures the longevity and performance of your AC/DC adapter:

• Cleaning: Disconnect the adapter from both the power outlet and the device before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Storage: Store the adapter in a cool, dry place when not in use. Avoid wrapping the cable too tightly around the adapter to prevent stress on the connections.
• Cable Care: The adapter cable is designed for durability, featuring high-quality copper wire and PVC insulation, and has undergone extensive bending tests. However, avoid sharp bends, kinks, or excessive pulling on the cable to prevent internal damage.
• Heat Dissipation: The adapter incorporates pure copper plates for efficient heat dissipation, reducing heat buildup during charging. Ensure adequate ventilation around the adapter during operation.
