The dewalt 18 gauge brad nailer is an excellent tool for every woodworker, trim carpenter, and diy enthusiast alike. However, despite its efficiency, it is not impervious to malfunctions. If you are encountering issues with your dewalt 18 gauge brad nailer not firing nails, then it’s crucial to diagnose the problem correctly.

One of the common issues that arise in this type of nailer is its firing mechanism. Understanding how it works is crucial, which is why we will provide you with a detailed explanation of the firing mechanism of dewalt 18 gauge brad nailer.

How does The Firing Mechanism Work?

Compressed air enters and moves the forward piston when the trigger valve is pulled. The forward piston enables the cylinder valve to open, which allows pressure to enter the cylinder. This pressure will force the driver blade forward, driving the nail into the workpiece.

Similarly, when the trigger is released, the rear piston functions, which releases the compressed air from the cylinder. It will then allow the spring to move the front piston back into its original position, which releases any residual pressure.

Here are some common reasons why the firing mechanism can malfunction:

  • Jammed nail: When the firing mechanism becomes jammed, it may be due to the nail feeding mechanism malfunctioning or nails not feeding correctly. This can also lead to other issues, like the driver blade not retracting, causing a double fire.
  • Low spring tension: If the magazine spring and the follower are not working correctly, there might be low tension, and nail feeding might malfunction. This can also lead to nail jams.
  • Trigger valve issues: Trigger valve problems can be anything from dirt inside the trigger valve causing it to malfunction or the valve not opening when triggered.
  • Improper maintenance: Poor maintenance can cause the firing mechanism to malfunction over time. Dirt buildup, worn-out parts, or not lubricating the necessary parts can all lead to firing problems.

A Dewalt 18 gauge Brad nailer is an effective tool that can last for years if correctly used and maintained. Knowing how the firing mechanism works can help fix any issue that might arise during its operation. If you encounter a problem with the firing mechanism, such as nail jams, low spring tension, trigger valve issues, or poor maintenance, you can now diagnose the possible cause and fix the problem.
