Using this DeWalt DWFP12231 18 Gauge Brad Nailer is easy. First, make sure to connect the 1/4 - inch fitting properly. You can adjust the depth of the nail drive without tools using the detents for accurate results. When you encounter a jam, use the tool - free jam release mechanism to remove the nail quickly. The adjustable belt hook is handy to keep the nailer close while you work. Keep in mind that the rear exhaust is designed to keep dirt and debris away from your work, so don't block it. For maintenance, since it has a long - life maintenance - free motor, you don't need to do much, but it's a good idea to clean the nailer regularly, especially the nose tip. Remove the non - marring nose tip and clean it as needed. And store it in the provided carrying case when not in use to protect it from damage.
