Bostitch nail guns are renowned for their reliability and performance. However, like any tool, they may encounter issues, such as not firing nails. In this technical guide, we will delve into the common reasons behind a Bostitch nail gun not firing and provide clear and concise steps to troubleshoot and resolve these issues, ensuring your nail gun gets back to its productive best.

1. Check Air Supply

One of the most common causes of a Bostitch nail gun not firing is an inadequate air supply. To resolve this:

• Ensure your compressor is properly connected and provides sufficient air pressure. Refer to your nail gun’s user manual for the recommended PSI.

• Confirm that the air hose is not damaged or leaking, and all connections are secure.

• Ensure the compressor is set to the appropriate PSI range for your nail gun.

2. Inspect the Nails

Sometimes, issues can arise from the nails themselves. Here’s what to do:

• Check the nail magazine for jammed or misaligned nails. Clear any obstructions.

• Ensure that you’re using the correct nail type and size specified by Bostitch for your nail gun model.

• Make sure the nails are loaded properly, and the magazine is not overfilled.

3. Examine the Firing Mechanism

The firing mechanism can be a source of problems. To troubleshoot:

• Inspect the trigger and safety contact tips. They should move freely without obstructions or damage.

• Check for wear or damage on the driver blade. A worn blade may not engage the nails properly.

• Lubricate the firing mechanism as recommended by the manufacturer using pneumatic tool oil.

4. Safety Interlock

Bostitch nail guns often have safety interlock mechanisms to prevent accidental firing. Ensure:

• The safety contact tip is pressed against the work surface before pulling the trigger. The nail gun won’t fire without this step.

• The safety mechanism isn’t stuck or obstructed in a way that prevents it from releasing.

5. Verify Power Source

If you’re using a corded electric Bostitch nail gun:

• Confirm that the power cord is undamaged and properly plugged into a functioning power outlet.

• Check the power switch to make sure it’s in the "on" position.

6. Troubleshoot Nail Gun O-Rings

Leaky O-rings can lead to insufficient pressure for firing. To address this:

• Inspect the O-rings for visible damage or wear. Replace any damaged O-rings following Bostitch’s guidelines.

• Lubricate the O-rings with pneumatic tool oil to maintain their sealing performance.

7. Proper Maintenance

Regular maintenance is key to a reliable nail gun. Make sure to:

• Keep your nail gun clean from dust and debris.

• Follow the manufacturer’s recommendations for maintenance intervals and procedures.

Conclusion

A Bostitch nail gun not firing can be frustrating, but in most cases, the issue can be resolved by following these troubleshooting steps. Always prioritize safety and handle your nail gun with care during the troubleshooting process. If the problem persists or is beyond your expertise, it’s advisable to consult a qualified technician or contact Bostitch customer support for further assistance. Proper maintenance and timely troubleshooting will keep your Bostitch nail gun in excellent working condition for many projects to come.
