Using the DeWalt DCH263R2 is easy. First, charge the 6.0AH 20V batteries with the high - speed charger. Then, insert the battery into the hammer. You can attach the low - vibration side handle and depth rod as needed. For drilling, select the appropriate drill bit and adjust the settings according to the material you're working on. When chipping, set the hammer to the right mode. Always wear safety gear like goggles and gloves. Keep the tool clean after use. Wipe it down with a dry cloth. Store it in a dry place. If the bit jams, don't force it. Use the factory - set clutch feature to reduce torque reactions. Also, if you're using it in a dark area, turn on the bright LED to see better. When not in use for a long time, remove the battery to avoid damage.
