Using your DeWalt 20V MAX* 1/4 in. brushless cordless impact driver is a breeze. First, make sure the tool is off before you insert a bit into the 1/4' hex drive. Once the bit is in place, you can turn on the tool. Use the variable speed trigger to control how fast the driver spins, depending on the job you're doing. If you're working in a dark area, the 3 - LED work light will help you see what you're doing. Just press the button to turn it on.
When it comes to safety, always wear safety goggles to protect your eyes from flying debris. Don't use the tool if it's damaged. Also, keep your hands dry and hold the tool firmly.
For maintenance, after each use, wipe down the tool with a clean, dry cloth. Check the bit for wear and tear and replace it if needed. Store the tool in a cool, dry place to keep it in good condition.
