Using this DeWalt demolition hammer is easy. First, make sure the battery is fully charged as it's a cordless tool. When you start using it, the electronic soft start will give you a smooth and safe start. To operate, just hold the tool firmly and press the trigger. The electronic brake will stop the wheel quickly once you let go of the trigger. When you encounter a pinch or stall, the electronic clutch will reduce the kick - back to keep you safe. For maintenance, regularly clean the tool to prevent dust build - up. Check the battery regularly and charge it properly. Also, make sure to store the tool in a dry place to avoid damage.
