4. Setup

1. Connect to Device: Insert the barrel connector of the Onerbl AC-DC Adapter firmly into the power input port of your YUEWXTER BD-001 Electric Weed Eater or 4-in-1 Grass Trimmer.
2. Connect to Power Outlet: Plug the adapter's two-prong plug into a standard 110V AC electrical wall outlet.

5. Operating Instructions

Once the adapter is correctly connected to both your device and a functional power outlet, your YUEWXTER BD-001 device should either power on directly or begin charging its battery, indicated by the device's charging indicator (if applicable).

Important Note on Batteries: Rechargeable batteries have a limited lifespan, typically lasting 1 to 3 years. If your device's battery is old or depleted, it may not accept a charge, even with a functional adapter. This is a battery issue, not a fault with the charger. If you are uncertain whether the battery or the charger is the cause of a charging problem, a voltmeter can be used to test the charger's output voltage.

6. Maintenance

• Cleaning: Keep the adapter clean and dry. Use a soft, dry cloth to wipe off any dust or dirt. Do not use liquid cleaners.
• Cable Care: Avoid sharp bends or kinks in the power cord. Do not place heavy objects on the cord.
• Storage: Store the adapter in a cool, dry place away from direct sunlight and moisture when not in use.

7. Troubleshooting

• Device Not Powering On or Charging:
  • Ensure the adapter's barrel connector is fully inserted into the device.
  • Verify the adapter is securely plugged into a working wall outlet. Test the outlet with another device if necessary.
  • Refer to the Important Note on Batteries in Section 5. An old or dead battery will not charge.
  • If the issue persists and you've ruled out battery problems, use a voltmeter to check the adapter's output voltage.
• Adapter Getting Warm: It is normal for the adapter to become slightly warm during operation. If it becomes excessively hot to the touch or emits a burning smell, immediately unplug it from the wall outlet and discontinue use.
