The Bostitch N66C Siding Nailer is a reliable tool for professionals and DIY enthusiasts when it comes to installing siding. However, if you’re experiencing double feed issues with this nailer, it can be frustrating and impact your efficiency. In this guide, we’ll help you understand, troubleshoot, and resolve the double feed problem quickly and effectively.

Identifying the Double Feed Issue

A double feed issue occurs when the nailer drives two nails at once, leading to misfires and an incomplete installation. It’s essential to understand the root causes of this problem to address it effectively.

Potential Causes of Double Feed:

1. Nail Selection: Using the wrong nails, or nails of inconsistent length, can lead to double feeding. Ensure you’re using the correct type and size of nails recommended for the N66C.

2. Dirty or Worn Parts: Dust and debris can accumulate in the nailer over time, causing the nail feed mechanism to malfunction. Worn or damaged parts, like the magazine or the feeder, can also lead to double feed problems.

3. Improper Nailer Operation: If the nailer is not operated correctly, it can cause double feeding. This includes holding down the trigger continuously, causing the nailer to fire when it’s not in contact with the work surface.

4. Air Pressure: Inconsistent or too high air pressure can result in the nailer driving nails too quickly, leading to double feeds.

Troubleshooting Steps

Here’s a step-by-step guide to troubleshooting and resolving the double feed issue with your Bostitch N66C Siding Nailer:

1. Nail Inspection:

• Ensure you’re using the correct nails specified in the manufacturer’s guidelines for the N66C.
• Verify that the nails are not damaged, bent, or rusted.

2. Clean the Nailer:

• Disconnect the nailer from the air supply.
• Remove any nails and clear the magazine.
• Inspect the nail feeder and the magazine for dirt, debris, or worn parts.
• Clean any accumulated dust and debris with compressed air or a brush.
• Inspect and replace any worn or damaged components.

3. Adjust Air Pressure:

• Ensure that the air pressure is within the manufacturer’s recommended range, typically between 70-120 PSI. Adjust it as needed.

4. Correct Nailer Operation:

• Only depress the trigger when the nailer is in contact with the work surface.
• Avoid continuously holding down the trigger when not nailing.

5. Test Fire:

• Reconnect the nailer to the air supply.
• Load the recommended nails.
• Test fire the nailer to ensure it’s feeding and firing correctly.

6. Monitor and Fine-Tune:

• Continue to monitor the nailer during use. If double feed issues persist, fine-tune the air pressure and monitor the nailer’s operation closely.

Safety Note

While troubleshooting and addressing the double feed issue, always prioritize safety. Disconnect the nailer from the air supply, wear appropriate safety gear, and handle the tool carefully.

In conclusion, the Bostitch N66C Siding Nailer is a reliable tool, but like any equipment, it can encounter operational issues.
