Why DeWalt DCN45RNN Nail Gun does not drive fasteners fully?
- J
  Jay MillerAug 13, 2025
  If your DeWalt Nail Gun isn't driving fasteners fully, several factors could be at play. First, check the depth adjustment and rotate it to a deeper setting. Ensure you're applying adequate force, securing the tool tightly to the workpiece. The material and fastener length should be appropriate for the application. New tools may require 500–1000 nails to mesh properly, so use shorter nails initially. If using longer ring shank nails, adjust the speed setting to position 2.

  If the motor of your DeWalt Nail Gun doesn't run when the trigger is depressed, first check if the trigger lock is engaged and unlock it. If the tool is stalled, rotate the stall release lever. If the driver blade doesn't return, remove the battery and manually push it back. Try resetting the tool's internal electronics by removing the battery, waiting 3 seconds, and reinserting it. Note that the motor stopping after 5 seconds is normal operation; release and re-depress the trigger. Also ensure that the battery and the tool are not hot; let them cool down if needed.
