Using your DeWalt DCD799L1 hammer drill is a breeze. First, charge the DCB230 20V MAX* 3.0Ah battery with the DCB112 charger. Once charged, insert the battery into the drill. Select the appropriate drill bit and secure it in the 1/2 in. ratcheting chuck. When drilling, start at a slow speed and gradually increase it as needed. The on - tool LED work light can be used in low - light areas. Make sure to keep the drill clean after each use. Wipe it with a dry cloth and store it in the kit bag provided. When not in use, remove the battery to avoid over - discharging. Don't use the drill in wet conditions to prevent damage. If you encounter any issues, contact DeWalt customer service.
