Using the DeWalt DCD799B hammer drill is easy. First, make sure you have a compatible 20V MAX* battery and charger (sold separately). Once you've charged the battery, insert it into the drill. Select the appropriate drill bit for your task and secure it in the 1/2 - inch ratcheting chuck. For masonry drilling, switch to the hammer drill mode. When working in tight spaces, take advantage of the compact design and the on - tool LED work light to see clearly. Remember, this drill can reach up to 1,650 RPMs and 28,050 BPMs, so adjust your speed according to the material. After use, remove the battery to prevent over - discharging. Keep the drill clean by wiping it with a dry cloth. Store it in a dry place to avoid damage. And always wear safety goggles and appropriate safety gear when using the drill.
