Using the DeWalt DCK303P2 is a breeze. First, charge the battery packs with the included charger. Then, insert the battery into the tool. You can choose different modes according to your needs. For quick work, use the Trigger Mode (High Speed). If you need more control, go for the Trigger Mode (Low Speed). The PushStart Mode is great for starting easily, and the Lock - On Mode is handy for continuous operation. When changing bits, you don't need a wrench; just use the tool - free bit change feature. To ensure the cutting depth is consistent, use the depth guide. When not in use, store the tools in the kit bag. Keep the battery in a cool, dry place. Regularly clean the tools to remove dust and debris. Don't use the tools if they are damaged, and always follow safety guidelines when operating them.
