The device comes in several varieties, and its features can depend on it from model to model.

It can be a struggle to find the right fit on your own if you’re new to the market. So, be sure to engage the dealer, and he will make your job much easier.

There is no such thing as one perfect unit for all projects. You will have to cycle between different devices to find the right fit.

So, if you’re not that sure about the project requirements, asking the dealer and sticking with established brands like DeWalt is the best option for you.

Moreover, the company that you get your finish nailer from also plays a huge role in how it will work.

This is why it is best that you carefully select a brand that is known for having good-quality products.

Talking about this, DeWalt is an American manufacturer that has a huge lineup of power tools that people can choose from.

When it comes to this, you should note that there are several models of finish nailers that you can purchase.

While all of these are amazing, there are also some issues that you can run into with them. If your

DeWalt finish nailer is running into problems, then going through this article should help you in finding some troubleshooting steps that can be used.

  1. Checking the Battery

The finish nailer from DeWalt is a cordless tool that works using a battery. This saves people the trouble of having to use air compressors every time they want to use a power tool.

Though, the user has to keep the battery in check at all times to avoid any problems with it. The first thing that you should check is if your battery is completely charged.

You can do this by plugging the finish nailer with the DeWalt charger and waiting till the LED light on it becomes stable. 

This should flash as long as the device is charging, which indicates that you should wait patiently. In case the LED light on your charger is not flashing, then this means that your battery might be loose.

You can easily take this out by holding the small button above the battery compartment and then sliding it down.

Once done, the user can install the battery back in tightly and see if it starts charging.

Other than this, the charger getting damaged is another reason why your battery might not be properly charging.

You can try replacing the fuse inside it to see if the problem is fixed. If not, then you will have to get the charger replaced with a new one.

  1. Clean Your Finish Nailer


Sometimes when trying to use the DeWalt finish nailer, people might notice that the device is not functioning properly. This usually means that something is stuck inside the moving parts of the power tool.

Keeping this in mind, you must clean the piston along with the motors inside the finish nailer every time you are done with your project.

This helps in preventing the device from clogging or running into issues like this in the future.

Additionally, people can also lubricate the power tool so that it runs smoothly. This helps in further preserving the motors used in your device and makes them last a long time without any issues.

Aside from this, the magazine and nosepiece of the device also require a thorough cleanup as this collects a lot of dust and debris.

Clearing it out can also prevent the particles from entering the moving parts of your device.

  1. Faulty or Broken Parts

If you are still getting the same problem with your finish nailer, then there is a high chance that some parts of it might be broken.


You can easily notice this by observing the tool and taking it apart. The broken parts can be replaced with new ones by ordering them from DeWalt.

Although, there might also be some users that feel hesitant about trying to fix the device on their own.

When it comes to this, they can contact the support team for DeWalt. You will then be connected with an agent that should help you in getting rid of the problem.

If the parts have to be fixed or replaced, then the team will ask you to bring the device to them. They will then get it repaired for you within a few working days. 

You can also get free replacements if your Finish nailer is still under warranty. But if you are thinking about claiming this service, then make sure that you go through the guidelines once.
