5. Operating Instructions

Once properly connected, the adapter will begin supplying power to your vacuum cleaner. If the vacuum cleaner is off, it will typically begin charging its battery. Refer to your vacuum cleaner's manual for specific charging indicators (e.g., LED lights).

Important Note on Batteries: Rechargeable batteries have a finite lifespan, typically lasting 1 to 3 years. If your vacuum cleaner's battery is old or depleted, it may no longer accept a charge, which is a battery issue, not a charger malfunction. If you suspect a battery issue, consult your vacuum cleaner's manufacturer or a qualified technician.

6. Maintenance

• Cleaning: Disconnect the adapter from both the power outlet and the vacuum cleaner before cleaning. Wipe the adapter with a dry, soft cloth. Do not use liquid cleaners or solvents.
• Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
• Inspection: Periodically inspect the adapter and its cable for any signs of wear, cuts, or damage.

7. Troubleshooting

• No Power/Charging:
  • Ensure the 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 battery is not at the end of its lifespan. An old or dead battery will not accept a charge, even from a functional adapter.
  • If you have a voltmeter, you can test the adapter's output voltage to confirm it is working correctly.
• Adapter Overheating: Disconnect the adapter immediately. Ensure it is in a well-ventilated area and not covered. If overheating persists, discontinue use and contact support.
• Physical Damage: If the adapter or cable is physically damaged, discontinue use immediately to prevent electrical hazards.
