Using the DeWalt D25872K is straightforward. First, make sure it's plugged in since it's a corded tool. When you start chipping, use the variable - speed dial to set the right speed based on the material you're working on. If it's thick or dense, you might want a higher speed. For horizontal or downward chipping on mid - to - lower walls and floors, this tool is a great choice. As you work, the SHOCKS Active Vibration Control® will help reduce the vibration you feel, so you won't get tired as quickly. Don't forget, you can use the Tag Ready™ feature to connect the tool to the DEWALT Tool Connect™ app and keep track of it. When it comes to maintenance, after each use, unplug the tool and clean it. Check the cord for any damage. And every once in a while, lubricate the moving parts as per the manufacturer's instructions. Be careful when using it around other people and always wear safety gear like gloves and goggles.
