Using the DeWalt DCK227D2 kit is a breeze. First, charge the 20V MAX* compact lithium - ion batteries using the included charger. Once charged, insert a battery into either the drill/driver or the impact driver. For the drill/driver, select the appropriate bit and adjust the torque settings according to your task. The 1/2 in. ratcheting chuck makes it easy to hold the bit securely. When using the impact driver, choose the right bit for driving screws. Remember to wear safety goggles and gloves for protection. As for maintenance, after each use, wipe the tools clean with a dry cloth. Keep the batteries in a cool, dry place and avoid over - charging them. Also, check the tools regularly for any signs of damage. If you notice any issues, stop using the tool and contact DeWalt's customer service.
