Using the DeWalt DCF845D1E1 impact driver is easy. First, choose the right battery for your needs - you've got the DCBP034 POWERSTACK Compact Battery and the DCB203 2Ah Battery. Insert the battery into the driver until it clicks into place. Then, select the appropriate speed on the 3 - speed switch according to your task. For smaller screws or more delicate work, use a lower speed. For larger screws, switch to a higher speed. When working in low - light areas, turn on the 3 - LED work light by pressing the button near the light. Remember to wear safety goggles when using the driver. As for maintenance, keep the tool clean. After each use, wipe it down with a dry cloth. If there's any dust or debris inside, use compressed air to blow it out. Also, make sure to charge the batteries properly and store them in a cool, dry place. If you want to track the tool, install the DEWALT® TOOL CONNECT™ Site Manager App and insert the optional chip (sold separately).
