Using the DeWalt DCK275C2 Combo Kit is a breeze. First, make sure your batteries are fully charged using the DCB107 charger. Once charged, insert the battery into either the drill/driver or the impact driver. For the drill/driver, select the appropriate drill bit for your task and insert it into the 1/2 - inch chuck. Tighten the chuck securely. When using the impact driver, insert the right bit into the 1/4 - inch chuck. Use the variable speed trigger to control the speed and power according to your needs. For example, start with a lower speed on delicate surfaces. The LED light on the tools will turn on when you pull the trigger and stay on for 20 seconds after release, helping you see in dark areas. As for safety, always wear appropriate safety gear like safety glasses. Keep your work area clean and free of clutter. When not in use, store the tools in the carrying bag provided. To maintain your tools, wipe them down after each use to remove dust and debris. Periodically check the batteries for any signs of damage. If you notice any issues with the tools, stop using them immediately and contact DeWalt customer service.
