Using your DeWalt DCF900H1 is a breeze. First, make sure the battery is fully charged. Insert the battery into the tool and it's ready to go. When starting a job, select the appropriate speed mode using the 4 - mode push - button switch. For jobs where you need precise torque, use the PRECISION WRENCH™ mode to avoid overtightening or fastener run - off. The variable - speed trigger allows you to control the speed according to your needs. When working in dark areas, turn on the on - tool LED work light. As for maintenance, keep the tool clean after each use. Wipe it down with a dry cloth. If the battery gets dirty, use a slightly damp cloth to clean it. Store the tool and battery in a dry place. Also, don't forget to check the battery's state - of - charge regularly using the 3 - LED fuel gauge. If you're not using the tool for a long time, remove the battery to prevent any potential damage. And always make sure to use the charger that comes with the kit to charge the battery properly.
