My Nailer Won’t Fire 

A nailer is a crucial tool for woodworkers, carpenters, and construction workers, However, like all power tools, a nailer can experience problems that can cause it to malfunction and leads to the complaint of its user that “My Nailer is not Firing!”. A nailer is used to shoot nails into wood or other materials with a high degree of precision and speed. It can save a lot of time and effort in nailing down wood planks, framing, and other construction projects. One of the most common issues that a nailer can encounter is when it won’t fire.

In this guide, first let’s explore some of the reasons why your nailer might not be firing, and then discuss how to troubleshoot to fix the problem.

1:Incorrect Nails:

One of the most common reasons why a nailer won’t fire is because the nails that are being used are not compatible with the tool.Using the appropriate size and type of nails for your nailer is crucial.  If the nails are too long or too short, the tool may not be able to fire them correctly. Additionally, if the nails are too thick or too thin, they may get jammed in the nailer, which can prevent it from firing. Let’s focus on how can we resolve this issue.


Initially Check the user’s manual that came with your nailer or the manufacturer’s website to determine the correct size and type of nails to use with your nailer. Ensure that the nails you are using are not bent, rusted, or damaged. If you use a strip of nails, ensure they are correctly aligned in the magazine.

2:Low Air Pressure:

Another reason why a nailer won’t fire is low air pressure. A pneumatic nailer requires a continuous supply of compressed air to function correctly. If the air pressure is too low, the nailer won’t have enough power to drive the nails into the material but this problem can be fixed easily.


Check the air pressure gauge on the nailer to make sure that it is set to the correct pressure. Most nailers require an air pressure of between 70 and 120 psi. If the pressure is too low, increase it to the recommended level. Also, check that your air compressor is capable of providing enough pressure for your nailer.

3:Air Leak

One common reason why your nailer won’t fire is an air leak. An air leak can cause a significant drop in the air pressure, affecting the tool’s ability to fire nails correctly. Air leaks can occur in several places in a nailer, including the hose, the regulator, or the fittings.


Ensure that you carefully examine the nailer’s hose, regulator, and fittings for indications of deterioration or damage. Verify that all the connections are firm and properly fastened. If you find any damage or wear, replace the damaged components immediately. Additionally, use Teflon tape on all threaded connections to ensure that they are airtight. This is how simply how your problem can be solved.

4:Dirty or Damaged Components

The internal components of a nailer can become dirty or damaged over time, which can cause the tool to malfunction. Dirty or damaged components can cause the nailer to misfire, jam, or not fire at all.


Clean the internal components of the nailer regularly to prevent dirt and debris from clogging the tool. Use a damp cloth or a brush to remove any dirt or debris from the nailer’s components. If you notice any damaged components, such as the driver or piston, replace them immediately.

5:Incorrect Trigger Operation

Sometimes, the reason why a nailer won’t fire is that the operator is not using the tool correctly. It is important to use the nailer’s trigger correctly to ensure that the tool fires the nails correctly. Let’s learn how to do this.


Review the user manual that came with your nailer to ensure that you are using the trigger correctly. The trigger should be pressed firmly and quickly released to fire the nail. Holding the trigger down for too long can cause the tool to jam or misfire. Also, ensure that you are using the correct firing mode, whether it is sequential or bump firing.

6:Jammed Nails

If a nailer has been used for an extended period, nails can become jammed in the tool. When this happens, the nailer won’t fire because the jammed nail is blocking the magazine and preventing new nails from feeding into the tool.


Disconnect the nailer from the air supply and remove the magazine from the tool. Check for any jammed nails and use pliers or a nail set to remove the jammed nail. Once the jammed nail has been removed, reassemble the nailer and test the firing function. By following the above steps your nailer will start working again.

7:Worn Out O-Rings

O-rings are small rubber components that help seal the nailer’s internal components and prevent air leaks. Over time, O-rings can wear out, crack, or become damaged, which can cause air leaks and prevent the nailer from firing.


 Inspect the nailer’s O-rings for any signs of wear or damage. Replace any damaged O-rings immediately. It is essential to use high-quality O-rings that are compatible with your nailer to ensure the best performance.

8:Clogged Air Filter

The air filter in your nailer helps to prevent debris and dirt from entering the tool and causing damage to the internal components but If the air filter becomes clogged, it can restrict the airflow, causing the nailer to malfunction and halt your working process. But no need to worry, there is way to fix this problem.


 Check the air filter in your nailer and clean it if it is dirty or clogged, you may also utilize compressed air or a brush with soft bristles. If the filter is in poor condition, it should be replaced with a new one. 

9:Damaged Driver

The driver in your nailer is responsible for driving nails into the material. If the driver is damaged or worn out, it can prevent the nailer from firing correctly.


The pro tip for this problem is to check the driver in your nailer and inspect it for any signs of damage or wear. If the driver is worned out, it will need to be replaced.

10:Low Nail Magazine

If your nailer won’t fire, it could be because the nail magazine is empty or low on nails. When the magazine is low on nails, it can cause the tool to misfire or not fire at all. Read on how to fix it.


Check the nail magazine in your nailer and make sure that it is loaded with enough nails. Refill the magazine if it is low.

11:Clogged Nailer Head

If your nailer won’t fire, it could be because the nailer’s head is clogged with debris or dirt. This can prevent the nails from feeding into the tool correctly.


Remove the nailer’s head and clean it thoroughly. Use a soft-bristled brush or compressed air to remove any dirt or debris. Once the nailer’s head is clean, reassemble the tool and test the firing function.


Q.1: Why is my nail gun not firing nails?

ANS: One possible reason for your nail gun not firing nails, but still triggering, could be inadequate air pressure setting. Another possible cause could be an obstruction in the nail feed mechanism. A third possibility is that the nails you are using are not suitable for the particular nail gun.

Q.2: Why is my nail gun only shooting air?

ANS: If you only hear air leaking when engaging the trigger, while firing a pneumatic nail gun, it’s likely that your tool’s “O-Ring” is not sealing properly.

Q.3:How much air pressure is needed for a nail gun?

ANS: The minimum pressure should be  at least 70 psi while 90 is a more useful target level.

Q.4:How much oil goes in an air nail gun?

ANS: In order to dissolve buildup and guarantee seamless initiation and termination, most pneumatic nailers and staplers necessitate 4-5 drops of pneumatic tool oil to be added into the air fitting every day, with the quantity adjusted depending on the level of usage..

Q.5: What causes a brad nailer to jam?

ANS: Lack of Adequate Oil can cause your nailer to jam. Adequate lubrication is crucial for the functioning of the air cylinder located in the nose of the nailer. Insufficient oil can result in sluggish nail feeding, which can lead to a jam.


In conclusion, a nailer that won’t fire can be frustrating, but there are several reasons why this may happen. By following the troubleshooting tips that we discussed in this guide, you can quickly diagnose and fix the problem, getting your nailer firing again in no time. It is important to ensure that you are using the correct size and type of nails, that the air pressure is correct, and that there are no air leaks or damaged components.

Additionally, make sure that you are using the trigger correctly and that the nailer is clean and free from debris. If none of these solutions work, it may be necessary to take the nailer to a professional for repair. 

Remember to always follow the manufacturer’s instructions and safety precautions when using power tools to prevent injury or damage to the tool. By fixing the problem through the guide that we discussed  you can get your nailer firing again and get back to your woodworking or construction project.
