Using the DeWalt D25892K is straightforward. First, make sure it's plugged into a proper power source since it's a corded tool. When starting a job, use the variable - speed dial to set the right speed based on the material you're working on. For thicker and denser materials, go for a lower speed at first and adjust as needed. When chipping, hold the hammer firmly and keep it at the right angle for the best results. Since this tool has SHOCKS Active Vibration Control®, you'll feel less vibration, but still take breaks to avoid any long - term discomfort. As for maintenance, after each use, clean the tool to remove any dust and debris. Check the power cord for any signs of damage. If you're using the Tag Ready™ feature, make sure the DEWALT Tag™ is properly attached and the DEWALT Tool Connect™ app is updated. Store the tool in the provided kit box in a dry place when not in use.
