Using the DeWalt DCD999T1 is a breeze. First, make sure to charge the DCB606 FLEXVOLT® battery with the included 6 Amp charger before use. Once charged, insert the battery into the drill. You can attach the 360° side handle for better control and the belt hook for easy carrying. When you're ready to start drilling, select the appropriate speed on the 3 - speed transmission based on your task. The heavy - duty chuck provides a strong grip on the drill bit, so you can work with confidence. The LED light is great for working in dark places. Use the 3 - mode LED to get the right amount of light. If you're using the spotlight mode, remember it has a 20 - minute shutoff to save battery. For asset management on the jobsite, you can insert the Tool Connect™ Chip DCE042 (sold separately) into the chip pocket and connect it with the Tool Connect™ Site Manager app. As for maintenance, keep the drill clean after each use. Wipe it down with a dry cloth. Avoid using it in wet conditions. Periodically check the chuck for any debris and make sure the battery is stored in a cool, dry place when not in use.
