3. Setup Instructions
Follow these steps to set up your onerbl AC/DC Adapter:
- Unpack the Adapter: Carefully remove the AC/DC adapter from its packaging. Inspect it for any visible damage.
- Verify Compatibility: Ensure your WORKPRO tool (W121015A, W122044A, W122045A) or other 12V device requires a 12V DC input with a compatible barrel connector.
- Connect to Device: Insert the DC output plug of the adapter firmly into the power input port of your WORKPRO tool or device.
- Plug into Power Outlet: Insert the AC input prongs of the adapter into a standard AC 100-240V wall outlet.
- Verify Power: Once connected, your device should indicate that it is receiving power or charging (e.g., a charging indicator light).
4. Operating Instructions
The onerbl AC/DC Adapter operates automatically once connected. It converts the incoming AC power to the stable DC power required by your device.
- Charging: When connected to a compatible WORKPRO tool, the adapter will supply power for charging its battery. Refer to your tool's manual for specific charging indicators and times.
- Direct Power: For devices that can operate directly from an external power source, the adapter will provide continuous power as long as it is plugged into an active outlet.
- Safety Features: The built-in protection mechanisms (over-voltage, over-heat, short-circuit, over-current) will automatically activate to protect both the adapter and your connected device in case of an electrical anomaly.
5. Maintenance
To ensure the longevity and optimal performance of your onerbl AC/DC Adapter, follow these maintenance guidelines:
- Keep Clean: Regularly wipe the adapter with a dry, soft cloth to remove dust and dirt. Do not use liquid cleaners.
