This cordset is intended as a direct replacement part. Refer to your specific DEWALT rotary hammer's owner's manual for detailed, model-specific installation instructions. The following are general guidelines:
- Disconnect Power: Ensure the rotary hammer is unplugged from the power source.
- Access Cord Connection: Open the tool's housing to access the internal cord connections. This may require removing screws and covers.

- Remove Old Cordset: Disconnect the old cordset wires from their terminals and remove any strain relief mechanisms.

5. Operating Instructions
Once the DEWALT N486031 Cordset is correctly installed on your rotary hammer, its operation is integrated with the tool's normal function. Ensure the cordset is fully plugged into a compatible, grounded electrical outlet before operating the tool. Always ensure the cord is free from kinks, cuts, or damage during use.
6. Maintenance
Regular inspection of the cordset is crucial for safe operation and longevity.
- Visual Inspection: Before each use, visually inspect the entire length of the cordset for any signs of damage, such as cuts, abrasions, exposed wires, or discolored insulation. Check the plug for bent prongs or cracks.
- Strain Relief: Ensure the cord's strain relief where it enters the tool and the plug is intact and functioning correctly.
- Cleaning: Keep the cordset clean and free of grease, oil, and chemicals that can degrade the insulation. Wipe with a damp cloth if necessary, ensuring it is unplugged and dry before use.
- Storage: Store the cordset in a clean, dry place, away from sharp objects or extreme temperatures. Avoid tightly coiling the cord, which can lead to internal wire damage.
If any damage is observed, replace the cordset immediately with a genuine DEWALT N486031 replacement part.
7. Troubleshooting
As a passive electrical component, troubleshooting for the cordset is straightforward.
- Tool Not Receiving Power:
- Check if the cordset is securely plugged into a live, grounded outlet.
- Inspect the cordset for visible damage (cuts, frayed wires, bent prongs).
- Verify the internal connections of the cordset to the tool are secure and correct.
- Test the outlet with another device to ensure it is functioning.
- Intermittent Power:
- This often indicates a loose connection or internal damage to the cordset. Discontinue use immediately.
- Inspect all connections and the cordset for damage.
If the cordset is suspected to be faulty, it must be replaced. Do not attempt to repair damaged cordsets.
