The Dewalt NG660 – A Reliable Tool for Professionals
Before addressing the reasons why your Dewalt NG660 may have stopped working, it’s important to appreciate what makes this tool so popular among professionals and DIY enthusiasts alike. The Dewalt NG660 is a heavy-duty pneumatic nailer used in various applications such as framing, decking, and roofing. It is renowned for its durability, strong performance, and user-friendly design.
With robust construction and advanced features, the Dewalt NG660 is engineered to withstand tough job site conditions. However, even the best tools can encounter issues, which brings us to the core of our discussion – why did yours stop working?
Common Reasons for Deactivation
Understanding frequent reasons your Dewalt NG660 might stop functioning can help you troubleshoot quickly and effectively. Here are some common issues:
1. Air Supply Issues
One of the primary reasons your Dewalt NG660 might suddenly stop working is inadequate air supply. Pneumatic tools rely heavily on air pressure to operate. If your compressor isn’t delivering enough air, your nailer will not function as intended.

Solutions for Air Supply Issues
- Check the air compressor: Ensure it’s set to the necessary PSI for your Dewalt NG660, typically between 90-110 PSI.
- Inspect hoses and fittings: Make sure there are no leaks or blockages that could restrict airflow. Check your air hose for damage or kinks that could hinder performance.
2. Jammed Nails
Another common issue with nailers, including the Dewalt NG660, is nail jams. A jammed nail can halt your work abruptly and lead to further complications if not addressed.
Symptoms of a Jammed Nail
- You hear the motor running, but no nails are firing.
- The nail gun feels sluggish or unresponsive.
Solutions for Jammed Nails
- Turn off the tool: Always disconnect the air supply before attempting to clear a jam.
- Open the feed chamber: Carefully remove any jammed nails following the manufacturer’s instructions.
- Check for nail size: Ensure you are using the correct nail size that the Dewalt NG660 is designed to handle.
3. Improper Maintenance
Regular maintenance is crucial for the longevity and reliability of your Dewalt NG660. Neglecting maintenance can lead to performance issues, and eventually, the tool may stop working altogether.
Common Maintenance Oversights
- Neglected lubrication
