Senco air nail guns are known for their efficiency and reliability. However, like any mechanical tool, they may occasionally experience issues. One common problem that users encounter is double feeding, where the nail gun feeds two nails at once instead of one. In this guide, we’ll explore the reasons behind double feeding and provide solutions to address this issue.

Understanding Double Feeding

Double feeding, also known as double fire or double shot, occurs when the nail gun inadvertently drives two nails in quick succession, which can result in damage to the tool, material, or even safety hazards. To resolve this problem, let’s investigate potential causes and solutions.

Possible Causes of Double Feeding

1. Nail Size Mismatch: Double feeding can occur if you are using nails that are not compatible with your nail gun. Ensure that you are using nails of the correct size and type recommended by the manufacturer.

2. Dirty or Worn Parts: Dust, dirt, and wear and tear on the nail gun‘s feeding and firing components can lead to double feeding. Regular maintenance and cleaning can help prevent this issue.

3. Low Air Pressure: Inadequate air pressure may cause the nail gun to misfire or double feed. Check and adjust the air pressure to match the tool’s requirements.

4. Damaged or Worn Driver Blade: If the driver blade is damaged or worn, it may not function properly, leading to double feeding issues. Inspect and replace the driver blade if necessary.

5. Improper Firing Technique: Rapid and excessive trigger pulls can lead to double feeding. Use a controlled and deliberate firing technique to avoid this problem.

6. Feeder Mechanism Issues: Problems with the feeder mechanism, such as misaligned or worn components, can result in double feeding. Inspect and maintain the feeder parts regularly.

Steps to Resolve Double Feeding Issues

1. Use the Correct Nails: Always use nails that match the manufacturer’s specifications for your Senco air nail gun model.

2. Inspect and Clean: Regularly inspect your nail gun for dirt and debris. Clean the tool, paying attention to the feeder and driver blade areas.

3. Check Air Pressure: Verify that your air compressor provides sufficient pressure as per the nail gun’s requirements.

4. Inspect the Driver Blade: Ensure the driver blade is in good condition and correctly positioned. Replace it if damaged or worn.

5. Practice Proper Firing Technique: Avoid rapid and repetitive trigger pulls. Use a controlled and deliberate firing technique to prevent double feeding.

6. Feeder Mechanism Maintenance: Inspect the feeder mechanism for any misalignment or worn parts. Lubricate or replace components as needed.

Conclusion

Double feeding issues in your Senco air nail gun can be resolved by understanding the potential causes and taking appropriate measures. By using the correct nails, maintaining your tool, and practicing proper firing techniques, you can ensure that your Senco nail gun operates smoothly and efficiently, reducing the risk of double feeding. If problems persist, consult your tool’s manual or contact the manufacturer’s support for further guidance.
