2. Setup

2.1 Battery Installation

Insert the 20V MAX* Compact 2.0Ah Battery Pack into the base of the nailer until it clicks securely into place. Ensure the battery is fully charged using the provided DCB112 charger before initial use. The nailer is compatible with other DEWALT 20V MAX* batteries, though larger batteries may increase the tool's weight.

2.2 Loading Pin Nails

To load pin nails, open the nail magazine. Insert the pin nails into the magazine, ensuring they are oriented correctly with the arrow on the nail strip facing downwards, towards the firing end of the tool. Slide the nail strip all the way to the left margin of the loading area. Close the magazine securely. The nailer supports 23 Ga. pin nails from 5/8 inch up to 1-1/2 inches in length.

3. Operating Instructions

3.1 Safety Precautions

WARNING: Always wear safety glasses when operating the pin nailer. Nails can ricochet or pop back out if they hit an obstruction like another nail or screw, posing a risk of eye injury.

3.2 Firing Mechanism

To fire a nail, the tool requires two triggers to be pressed in sequence. First, press the lower trigger (contact trip) against the workpiece. Then, press the main trigger to actuate the nailer. This two-step process enhances safety during operation.

3.3 Applications and Nail Visibility

This pin nailer is ideal for delicate applications such as trim work and molding where minimal nail holes are desired. The 23 Ga. pins create extremely small holes that are barely visible, often requiring little to no filling after installation.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your DEWALT Pin Nailer.

  • Tool-Free Jam Release: In case of a nail jam, utilize the tool-free jam release mechanism to quickly clear obstructions without requiring additional tools.
  • Serviceable Driver Blade: The driver blade is designed to be serviceable, allowing for maintenance or replacement if necessary to maintain consistent performance.
  • General Cleaning: Keep the tool clean and free of debris. Use a dry cloth to wipe down the exterior. Do not use harsh chemicals or abrasive cleaners.

5. Troubleshooting

Common issues and their solutions:

  • Nailer Not Firing:
    • Ensure the battery is fully charged and properly seated.
    • Verify that both the contact trip (lower trigger) and the main trigger are pressed correctly and in sequence.
    • Check for a nail jam using the tool-free jam release.
  • Low Nail Lockout: The tool features a low nail lockout system with an LED indicator. If the LED illuminates, it signifies that the nail magazine is nearly empty and requires reloading to prevent dry firing and potential damage to the workpiece or tool.
  • Nails Not Driving Fully:
    • Adjust the tool-free depth adjust mechanism to increase the driving depth.
    • Ensure the correct nail length is being used for the material.
