Using the DeWalt DCD999T1 is straightforward. First, insert the FLEXVOLT battery into the drill. You can choose from the three - speed transmission to match the task you're doing, like drilling through wood or metal. The 360° side handle can be adjusted to your comfort for better control. When working in dark spaces, switch on the 3 - mode LED for light. The spotlight mode will stay on for 20 minutes, which is handy for longer jobs. For asset management on the jobsite, you can insert the Tool Connect™ Chip DCE042 (sold separately) into the chip pocket and use the app. When it comes to maintenance, keep the drill clean. After use, wipe it down to remove dust and debris. Charge the battery properly using the 6 - Amp charger provided in the kit. Store the drill in the kit bag when not in use to protect it. Make sure to use the right bits for different materials and always check the bit grip in the heavy - duty chuck before starting work.
