Using the DeWalt DCN681D1 narrow crown stapler is easy. First, charge the 2.0Ah battery with the included charger. Once charged, insert the battery into the stapler. Load 18-gauge 1/4-inch narrow crown staples that are between 1/2 inch and 1-1/2 inches long into the magazine. Adjust the staple depth using the tool-free depth adjustment feature to get the perfect countersinking for your project. When you're ready to start stapling, just press the stapler against the work surface and pull the trigger. The multi-functional LED lights will help you see your workspace and also show you if there are any issues with the tool. Remember, the low nail lockout feature is there to prevent dry firing, so when it engages, it's time to reload staples. As for maintenance, keep the stapler clean. Wipe it down after each use to remove dust and debris. If the driver blade stalls, use the integrated tool-free stall release lever to quickly reset it. Store the stapler in the included kit bag when not in use to protect it from damage.
