Package Contents

Setup
- Identify the Charge Port: Locate the charge port on your Arrow Fastener T50DCD Cordless Electric Staple Gun. It should be a circular port designed for a barrel plug.
- Connect the Adapter: Carefully insert the barrel plug tip of the UpBright AC/DC Adapter into the charge port of your stapler. Ensure a snug fit.
- Plug into Power Outlet: Insert the adapter's prongs into a standard wall power outlet.


Operating Instructions
Once the adapter is properly connected to the stapler and plugged into a live wall outlet, the stapler's battery will begin charging. The UpBright adapter itself does not have an indicator light. Refer to your Arrow Fastener T50DCD stapler's user manual for information regarding its charging indicator lights and expected charging times.
Always ensure the stapler is turned off before connecting the charger.

Maintenance
- Cleaning: Disconnect the adapter from the power outlet and the device before cleaning. Use a dry, soft cloth to wipe the adapter. 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 moisture. Avoid wrapping the cord too tightly around the adapter.
- Inspection: Periodically inspect the adapter and its cable for any signs of damage, such as cuts, fraying, or bent prongs. If damage is found, discontinue use immediately.
Troubleshooting
- Device Not Charging:
- Ensure the adapter is securely plugged into both the wall outlet and the device.
- Verify the wall outlet is functional by plugging in another appliance.
- Check the device's battery condition. If the battery is old or damaged, it may not accept a charge.
- Adapter Feels Warm: It is normal for the adapter to feel slightly warm during operation. If it becomes excessively hot, disconnect it immediately and contact customer support.
- Incorrect Connector: If the adapter's barrel plug does not fit your device, ensure you have the correct model. This adapter is specifically designed for devices requiring a barrel plug, not a USB connector.
