Using the DeWalt DCST925M1 is easy. First, charge the 20V MAX* 4.0Ah Lithium Ion Battery with the included charger. Once it's charged, insert the battery into the trimmer. You can choose between high and low speed using the control switch on the trimmer, depending on whether you're dealing with thick overgrowth or just need a quick trim. The variable - speed trigger allows you to adjust the power as you go. When the line runs out, you can use the bump - feed feature to add more line. For safety, always wear protective gear like gloves and goggles. Don't operate the trimmer in wet conditions. To maintain your trimmer, clean it after each use. Remove any grass or debris from the cutting head and the body. Keep the battery in a cool, dry place when not in use. If you notice any issues, check the manual or contact DeWalt support.
