A Bostitch roofing nailer is a reliable and essential tool for roofing professionals and DIY enthusiasts. However, like any tool, it can encounter issues. If you find yourself asking, "Why won’t my Bostitch roofing nailer fire?" you’re in the right place. In this article, we will explore common reasons for this problem and how to troubleshoot it effectively.

1. Insufficient Air Pressure:

One of the primary reasons a Bostitch roofing nailer won’t fire is insufficient air pressure. Ensure that your air compressor is providing an adequate and consistent supply of compressed air.

Solution:

• Check the air compressor’s pressure gauge and adjust it to the recommended PSI for your nailer (typically 70-120 PSI for roofing nailers).
• Inspect the air hose for any kinks or blockages that might impede air flow.

2. Nail Jam or Loading Issues:

A jammed nail in the magazine or improper loading of nails can prevent the nailer from firing.

Solution:

• Disconnect the nailer from the air supply.
• Open the magazine and remove any jammed nails.
• Reload the nail magazine with the correct nail collation and orientation according to your nailer’s manual.

3. Worn or Damaged O-Rings:

Over time, the O-rings inside the nailer may wear out or become damaged, affecting its firing mechanism.

Solution:

• Consult the user manual for your Bostitch roofing nailer for guidance on locating and replacing O-rings.
• Ensure you have the appropriate replacement O-rings and a repair kit.

4. Incorrect Depth Setting:

If the depth adjustment on your nailer is set too low, it may not fire nails properly.

Solution:

• Adjust the depth setting according to the material you’re nailing into. Consult your nailer’s manual for guidance.

5. Exhausted Fuel Cells or Batteries:

For cordless Bostitch roofing nailers, an exhausted fuel cell or low battery can lead to firing issues.

Solution:

• Replace the fuel cell or recharge the battery according to the manufacturer’s instructions.

6. General Maintenance:

Regular maintenance is essential for the proper functioning of your nailer. Neglecting it can lead to various issues, including firing problems.

Solution:

• Periodically clean and lubricate the nailer as instructed in the user manual.
• Ensure all parts and fasteners are tightened and secure.

7. Faulty Trigger or Firing Mechanism:

In some cases, a faulty trigger or firing mechanism may be the root cause of the problem.

Solution:

• If the above steps do not resolve the issue, consult the manufacturer’s support or a qualified technician to diagnose and repair the nailer’s internal components.

Conclusion:

A Bostitch roofing nailer not firing can be a frustrating issue, but most of the time, it can be resolved with simple troubleshooting steps. Regular maintenance, correct air pressure, and proper loading of nails are critical to preventing firing problems. If you’ve tried all the solutions mentioned and the issue persists, don’t hesitate to seek professional help or contact Bostitch customer support for further guidance.
