Using the DeWalt DCD471X1 is a breeze. First, make sure the battery is fully charged. You can use the included charger to charge the DCB609 FLEXVOLT® 20V/60V MAX* 3Ah Battery. When you're ready to drill, select the appropriate bit and insert it into the 7/16 in. Hex Quick - Change chuck. It's really easy to change bits with this chuck. Next, choose the right speed setting for your job. You can use the 2 - speed settings (0 RPM to 400 RPM/0 RPM to 1320 RPM) and switch between them using the Quick - shift speed selector. As you start drilling, keep an eye on the red LED indicator. If it lights up, it means the DEWALT anti - rotation E - Clutch System has detected a bind - up situation and has shut down the drill to protect you. Now, for some important notes. Always wear appropriate safety gear, like goggles and gloves, when using the drill. Don't use the drill in wet conditions or near flammable materials. Also, don't force the drill too hard. Let the power of the drill do the work. When it comes to maintenance, after each use, clean the drill with a dry cloth. Check the chuck regularly to make sure it's clean and working properly. Store the drill in the included kit bag in a dry place. And if you want to keep track of your drill, install a DEWALT tool tag and use the DEWALT Tool Connect app.
