Things You'll Need
A spare DeWalt battery
A spare magazine for your nail gun
While DeWalt makes several different types of nail guns, most of the steps described here will apply to all of them. With any gun, regular inspection and cleaning will minimize needed repairs.
Always remove the battery and magazine (or air hose) before attempting any troubleshooting, especially when clearing jams.
A DeWalt nail gun is a great way to save time on home improvement projects, but only if it is working. Learning how to troubleshoot your DeWalt nail gun can save you the time and effort of contacting customer support, and get you back to your project in little time.
Check the battery. Before attempting any other troubleshooting, make sure your DeWalt nail gun has a freshly charged battery. Charge or replace the battery before proceeding to other steps.
Clean your DeWalt nail gun. Nail guns accumulate dirt and debris over time and that can negatively impact the function of the gun. Thoroughly clean the entire gun, and spend extra time on the nosepiece and magazine, as these are the two places most likely to be affected by dirt and debris.
Check your fasteners. Make sure you are only using fasteners (nails) recommended by DeWalt, and ensure you are using the appropriate size for your nail gun.
Check, and if necessary replace, your magazine. If you've cleaned your gun's magazine and you are still having problems with jams and misfeeds, check you magazine to make sure it isn't worn or damaged. If it is, contact DeWalt for a replacement.
Clear out any jams in your Dewalt nail gun. Remove the battery and the magazine and make sure there are no fasteners causing a jam in the mechanism. If you see a jammed fastener, remove it and manually push the driver blade back up. Reinsert the battery and magazine.
Check your depth adjustment. If your fasteners are driving, but are either going in to deep or not deep enough, rotate your DeWalt nail gun's depth adjustment wheel until the desired depth is achieved.
If none of the previous steps rectify your problem contact DeWalt customer support by going to www.dewalt.com/us.service.
