Using the Bosch GSR12V - 300HXN screwdriver is easy. First, make sure you have a fully - charged battery (sold separately) and insert it into the tool. Choose the appropriate bit for your job and insert it into the quick - change 1/4 - inch hex drive chuck. You can adjust the speed using the two - speed transmission. For high - power tasks, select the 0 - 460 rpm setting, and for high - speed jobs, go for the 1,750 rpm setting. The 20 + 1 clutch settings let you control the torque precisely, so you don't damage the fasteners. When working in dark areas, turn on the LED light. As for maintenance, after each use, wipe the tool with a clean, dry cloth. Keep the chuck clean and lubricated to ensure smooth bit changes. Store the tool in a dry place. And always remember to remove the battery when not in use for a long time.
