Are you experiencing frustration with your Bostitch finish nailer not shooting nails as it should? You're not alone. This common issue can be caused by several factors, and we're here to help you troubleshoot and resolve the problem. In this guide, we'll explore potential causes and provide step-by-step solutions to get your Bostitch finish nailer shooting nails like new again.
Understanding Your Bostitch Finish Nailer
Before we dive into troubleshooting, let's briefly understand how your Bostitch finish nailer works. Finish nailers use compressed air to drive nails into various materials. They're designed for precision and are ideal for trim work, moldings, and other fine woodworking projects. A typical Bostitch finish nailer operates at around 70-100 PSI and uses 15-16 gauge nails, usually 1-2.5 inches in length.
Common Reasons Why Your Bostitch Finish Nailer Won't Shoot Nails
Several factors can cause your Bostitch finish nailer to stop shooting nails. Let's explore the most common ones:

- Air Pressure Issues: Insufficient air pressure can prevent your nailer from firing. The recommended pressure range for your Bostitch finish nailer is 70-100 PSI.
- Clogged Air Filter: A clogged air filter can restrict airflow, leading to insufficient power to drive nails.
- Jam or Broken Nail: A jammed or broken nail in the nose of the nailer can prevent new nails from feeding correctly.
- Worn-out Nail Driver: The nail driver (also known as the 'O' ring) can wear out over time, causing the nailer to lose power and fail to shoot nails.
- Incorrect Nail Size: Using nails that are too large or too small for your nailer can cause feeding issues and prevent the nailer from firing.
Step-by-Step Troubleshooting Guide
Check Air Pressure
Ensure your air compressor is set to the correct pressure range (70-100 PSI) and that there are no leaks in the air hose. You can use an air pressure gauge to verify the pressure at the nailer's inlet.
Clean the Air Filter
Regularly clean your nailer's air filter to prevent clogging. Consult your user manual for the exact location of the air filter in your specific Bostitch model. Most air filters can be cleaned with compressed air or a soft brush.
Clear Nail Jams
If you suspect a jammed or broken nail is causing the issue, follow these steps to clear the jam:

- Disconnect the nailer from the air compressor and unplug it if it's electric.
- Remove the nosepiece and any jammed or broken nails using needle-nose pliers.
- Inspect the nosepiece for any signs of damage or wear. If necessary, replace it with a new one.
Inspect and Replace the Nail Driver (O-Ring)
Inspect the nail driver (O-ring) for signs of wear. If it's damaged or worn, replace it with a new one. Consult your user manual for the correct size and type of O-ring for your Bostitch model.
Use the Correct Nail Size
Ensure you're using the correct nail size for your nailer. Using nails that are too large or too small can cause feeding issues and prevent the nailer from firing. Always use high-quality nails designed for your specific nailer to minimize jams and other issues.
Preventative Maintenance Tips
To keep your Bostitch finish nailer in top working condition and prevent issues like nails not shooting, follow these maintenance tips:
- Regularly clean your nailer, paying special attention to the nosepiece, air filter, and other moving parts.
- Store your nailer in a dry place, away from extreme temperatures and moisture.
- Lubricate moving parts with a suitable lubricant, as recommended in your user manual.
- Inspect your nailer regularly for signs of wear or damage, and replace worn parts promptly.
By following these troubleshooting steps and maintenance tips, you should be able to resolve most issues with your Bostitch finish nailer not shooting nails. If you've tried these steps and are still experiencing problems, it may be time to contact Bostitch customer support or consult a professional repair service.
