If you’re experiencing issues with your Bostitch roofing nailer failing to fire, it can be frustrating and impede your work. However, understanding the common reasons behind this problem and the steps to troubleshoot it can save you both time and money. In this article, we’ll provide clear and concise guidance for diagnosing and fixing issues with your Bostitch roofing nailer.

Common Reasons for a Bostitch Roofing Nailer Not Firing:

1. Air Supply Issues:

A frequent cause of a roofing nailer not firing is insufficient air supply. Ensure that your compressor is functioning correctly, and the pressure is set within the recommended range for your nailer (usually 70-120 PSI). Check for air leaks in the hose or connections, as this can disrupt the nailer’s operation.

2. Jammed Nails:

A jammed nail in the magazine can prevent the nailer from firing. Open the magazine and remove any jammed nails. Be sure to follow the manufacturer’s instructions for unjamming your specific Bostitch model.

3. Insufficient Lubrication:

Inadequate lubrication can cause the nailer’s moving parts to become sluggish. Regularly apply a few drops of pneumatic tool oil into the air inlet to maintain smooth operation.

4. Worn or Damaged Seals:

The O-rings and seals in your nailer can wear out over time, leading to air leaks and reduced firing performance. Inspect the seals for visible wear or damage, and replace them as necessary.

5. Depth Adjustment Setting:

Check your depth adjustment setting to ensure it’s properly configured for the type of material you’re nailing. Incorrect settings can lead to misfires or no firing at all.

Troubleshooting Steps:

1. Verify the Air Supply:

• Ensure the air compressor is working correctly.
• Check for any leaks in the air hose and connections.
• Confirm the pressure setting is within the recommended range.

2. Clear Nail Jams:

• Open the magazine and remove any jammed nails according to the manufacturer’s instructions.

3. Lubricate the Nail Gun:

• Apply a few drops of pneumatic tool oil into the air inlet.

4. Inspect Seals:

• Carefully examine the O-rings and seals for wear or damage.
• Replace any damaged seals with genuine Bostitch parts.

5. Adjust Depth Settings:

• Check and adjust the depth setting to match the material you are nailing.

Conclusion:

Diagnosing and fixing a Bostitch roofing nailer that won’t fire can often be straightforward if you follow a systematic approach. By checking the air supply, addressing nail jams, ensuring proper lubrication, and inspecting seals and depth settings, you can significantly improve the performance of your nailer. Always refer to the manufacturer’s guidelines and safety precautions when working with pneumatic tools. With a well-maintained nail gun, you can continue your roofing projects with ease and efficiency.
