Using this DeWalt impact driver kit is easy. First, charge the DCB203 battery with the DCB107 charger. Then, insert the charged battery into the impact driver. When using the impact driver, adjust the speed according to your needs with the variable - speed trigger. It's great for driving screws in tight spaces due to its compact size. For delicate surfaces, use a lower speed to avoid damage. When you're done, store the impact driver in the tool bag. Keep the battery in a cool, dry place. Regularly check the motor and clean any debris from the driver to maintain its performance. Also, make sure to wear appropriate safety gear like goggles when using the tool.
