What to do if DeWalt Nail Gun motor does not run with trigger depressed?

  If the motor of your DeWalt Nail Gun doesn't run when you depress the trigger, several factors could be at play. First, ensure the trigger lock isn't engaged. If the tool is stalled, rotate the stall release lever. If the driver blade doesn't return, remove the battery and manually push the driver blade back. If the tool is in sequential actuation mode, depress the contact trip first or switch to bump mode. To reset the tool's internal electronics, remove the battery, wait 3 seconds, and reinsert it. Note that the motor stopping after 5 seconds is normal operation; release and redepress the trigger. If none of these resolve the issue, the terminals or internal electronics may be damaged, or the trigger itself might be faulty.

  If the motor of your DeWalt Nail Gun runs but doesn't fire, several factors could be at play. First, the dry-fire lockout might be engaged; try loading nails into the magazine. Second, the battery charge might be low, or the battery could be damaged; check the charge level and replace or charge the battery if needed. Lastly, a nail could be jammed, preventing the drive blade from returning to its home position; remove the battery, clear any jammed nails, cycle the stall release lever, and manually push the driver blade up if necessary before reinserting the battery.

  If the motor of your DeWalt Nail Gun does not run when the contact trip is depressed, start by checking if the trigger lock is engaged and unlock it. Also, check if the dry fire lock out is engaged; if so, load more nails into the magazine. If the tool is stalled, rotate the stall release lever. Note that the motor will stop running after 5 seconds, which is normal operation; release and redepress the contact trip to continue.

How to fix a DeWalt DCN691 Nail Gun that doesn't drive nails all the way in?

  If your DeWalt Nail Gun operates but doesn't fully drive fasteners, first check the depth adjustment and set it to a deeper setting. Ensure the tool is firmly applied to the workpiece. If using bump mode with long nails (DCN692 only), switch to sequential mode. Consider the material and fastener length; if stalling occurs, use appropriate materials and fastener lengths. Remove the no-mar tip if it's attached. New tools may require 500–1000 nails to run-in. If driving longer ring shank nails in soft woods or into harder materials in speed 1, adjust the speed setting to position 2.

  If the motor of your DeWalt Nail Gun doesn't run when you depress the trigger, several factors could be at play. First, ensure the trigger lock isn't engaged. If the tool is stalled, rotate the stall release lever. If the driver blade doesn't return, remove the battery and manually push the driver blade back. For sequential actuation mode, depress the contact trip before firing, or switch to bump mode (DCN692 only). Try resetting the tool's electronics by removing the battery for 3 seconds and reinserting it. Note that the motor will stop running after 5 seconds, which is normal operation; release and redepress the trigger to continue.

  Thomas HuangAug 26, 2025
  If your DeWalt Nail Gun motor doesn't run when you depress the contact trip, start by checking if the trigger lock is engaged and unlock it. Another possibility is that the dryfire lockout is engaged, preventing the contact trip from traveling fully; load more nails into the magazine. Also, the tool might be stalled, which locks the motor; rotate the stall release lever to release it. If the driver blade doesn't return, remove the battery and manually push the driver blade back to its home position. Keep in mind that the motor stopping after 5 seconds is normal operation; release and redepress the contact trip.

Why DeWalt DCN691 operates, but no fastener is driven?

  Debra GuzmanAug 25, 2025
  If your DeWalt Nail Gun operates, but no fastener is driven, it could be due to a few reasons. Check if there are nails in the magazine and load them if necessary. Ensure you are using the correct size and angle nails as recommended. Also, inspect the nosepiece and magazine for any debris and clean them if needed.
