And when it comes to nailing tasks, a Bostitch Brad Nailer is a trusted companion for many. However, what do you do when your go-to nail gun suddenly refuses to cooperate and won’t fire? It’s a frustrating scenario, but fear not, for in this article, we will explore common issues that can cause your Bostitch Brad Nailer to misfire and guide you through troubleshooting steps to get it back in action.

Understanding the Basics

Before we dive into problem-solving, let’s get to know the star of the show – your Bostitch Brad Nailer. This versatile tool is designed to drive brad nails into various materials, making it an ideal choice for trim work, paneling, and delicate woodworking. The Bostitch brand is renowned for producing reliable and durable nailers, but even the best tools can encounter hiccups now and then.

Possible Reasons Your Bostitch Brad Nailer Won’t Fire

Several factors can lead to your Bostitch Brad Nailer failing to fire, and it’s crucial to identify the root cause. Here are some common issues:

1. Air Pressure Problems

Your nailer relies on compressed air to function correctly. If the air pressure is too low, your nailer might not have the power to drive the nails effectively.

Troubleshooting Steps:

  • Check the air compressor’s pressure gauge to ensure it’s within the recommended range (typically 70-120 PSI).
  • Examine the air hose for leaks, and ensure it’s connected securely to the nailer.

2. Jam or Obstruction

Nail jams or obstructions in the nail magazine can impede the firing process. Even a small piece of debris can cause issues.

Troubleshooting Steps:

  • Disconnect the air supply.
  • Open the nail magazine and carefully remove any jammed nails or debris.
  • Inspect the nails for damage and replace any bent or deformed ones.

3. Incorrect Nail Size

Using the wrong size of brad nails can lead to misfires. Ensure the nails you’re using are compatible with your Bostitch Brad Nailer model.

Troubleshooting Steps:

  • Refer to your nailer’s user manual to confirm the recommended nail size.
  • Verify that the nails you’re using match the gauge and length specifications.

4. Maintenance Neglect

Regular maintenance is crucial to keep your nailer in top shape. Dust and debris can accumulate over time, affecting its performance.

Troubleshooting Steps:

  • Clean the nailer’s nosepiece and magazine thoroughly.
  • Lubricate moving parts as per the manufacturer’s instructions.
  • Check for worn-out or damaged O-rings and seals, replacing them if necessary.

5. Trigger and Safety Mechanism Issues

A malfunctioning trigger or safety mechanism can prevent the nailer from firing.

Troubleshooting Steps:

  • Carefully inspect the trigger and safety mechanisms for damage.
  • If you notice any issues, contact Bostitch’s customer support for guidance or replacement parts.

6. Electrical or Wiring Problems (Electric Brad Nailers)

If you’re using an electric brad nailer, electrical issues can cause problems. Check the power source and wiring for faults.

Troubleshooting Steps:

  • Ensure the power cord is intact and plugged in securely.
  • If you suspect electrical issues, consult a professional electrician.


Your Bostitch Brad Nailer is a reliable tool, but like all equipment, it can experience hiccups. By understanding the potential causes of misfiring and following the troubleshooting steps, you can quickly get your nailer back to its efficient, nail-driving self. Remember that regular maintenance and proper handling can help prevent issues and extend the life of your Bostitch Brad Nailer, ensuring it remains your trusted companion on all your nailing tasks.
