Using the DeWalt D25810K is easy. First, make sure it's plugged in as it's a corded tool. Hold it firmly with the D - ring main handle and the side handle. Turn it on, and you're ready to start chipping or demolishing. For best results, keep the tool perpendicular to the surface you're working on. When using it for long periods, take breaks to avoid fatigue, as the anti - vibration features will reduce discomfort but not eliminate it completely. As for maintenance, after each use, unplug the tool and wipe it down to remove any dust or debris. Check the chuck regularly to ensure it's in good condition. If you notice any issues, refer to the warranty terms for support. Remember, following these steps will keep your hammer working well for a long time.
