Using your DeWalt D25911K demolition hammer is easy. First, make sure it's properly plugged in as it's a corded tool. When starting a job, hold the hammer with the rear handle for a comfortable grip, especially when doing horizontal or downward chipping. For dust control, you can link it to the DCV585 60 - Volt MAX dust extractor using the wireless tool control technology. If you want to keep track of the hammer, attach a DEWALT Tag and use the Tool Connect app. When using it on concrete, let the hammer's high - impact energy do the work. Don't force it too much. For safety, always wear proper protective gear like goggles and gloves. After each use, clean the hammer to remove any debris. Check the chuck regularly to ensure it's in good condition. If you're not using the hammer for a long time, store it in a dry place.
