A Bostitch roofing nailer is a reliable tool for securing roofing materials efficiently. However, if you encounter the issue of double firing, where the nailer drives two nails instead of one with a single trigger pull, it can be frustrating and impact your project’s quality. In this article, we’ll provide you with accurate, clear, and concise information about the causes of double firing and practical solutions to resolve this issue.

Causes of Double Firing

1. Insufficient Trigger Release: Double firing often occurs when the trigger is not released fully after firing the first nail. This incomplete release can cause the nailer to cycle again, firing a second nail unintentionally.

2. Air Pressure Issues: Inconsistent or fluctuating air pressure can lead to double firing. If the pressure is too high, the nailer may continue cycling even after releasing the trigger.

3. Worn or Damaged Trigger Mechanism: Over time, the trigger mechanism of the nailer can wear out or become damaged. This can result in a failure to reset correctly after each shot.

4. Nail Jam: A jammed nail in the nail magazine can obstruct the smooth cycling of the nailer, causing it to double fire when the obstruction is released.

Solutions to Prevent Double Firing

1. Proper Trigger Technique: Ensure you release the trigger completely after each nail is fired. Maintain steady pressure during the trigger pull without excessive force.

2. Consistent Air Pressure: Use a reliable air compressor and adjust the air pressure to the manufacturer’s recommended range, typically between 70 to 120 PSI. Inconsistent air pressure can lead to double firing.

3. Inspect and Maintain the Trigger Mechanism: Regularly inspect the trigger mechanism for any wear or damage. If you notice any issues, consider replacing the trigger mechanism or contacting a qualified technician for repair.

4. Prevent Nail Jams: Keep the nail magazine clean and free from debris or obstructions. A jammed nail can cause double firing once it’s dislodged. Ensure the nail coil is loaded properly and is not tangled.

Troubleshooting Double Firing

If you experience double firing with your Bostitch roofing nailer, here are steps to troubleshoot the issue:

1. Disconnect the Air Supply: Before troubleshooting, disconnect the nailer from the air supply for safety.

2. Release the Magazine: Open the magazine and check for any jammed nails. Remove any obstructions, and ensure the nails are properly seated.

3. Inspect the Trigger Mechanism: Examine the trigger mechanism for any visible wear or damage. Replace or repair as necessary.

4. Check Air Pressure: Ensure your air compressor is set to the recommended pressure range for your nailer.

5. Practice Trigger Control: Focus on your trigger control technique to prevent double firing. Pay attention to a complete trigger release.

Conclusion

A Bostitch roofing nailer is a valuable tool for roofing projects, but the issue of double firing can hinder your progress and affect the quality of your work. By understanding the causes of double firing and implementing the provided solutions, you can effectively address this problem. Proper trigger technique, consistent air pressure, regular maintenance, and vigilance in preventing nail jams are key to ensuring your Bostitch roofing nailer performs reliably and efficiently.
