Using the Bosch GDR18V - 1400B12 is a breeze. First, make sure the battery is fully charged. Insert the battery into the tool until you hear a click. Then, select the appropriate insert bit for your task and fit it into the 1/4 inch hex drive chuck. The power groove in the chuck will hold the bit firmly. When you're ready to start, simply hold the tool with the soft slim - grip handle. Press the trigger to start the impact driver. You can adjust the speed and torque according to your needs. For dark work areas, the built - in LED light will come in handy. As for maintenance, after each use, wipe the tool clean with a dry cloth. Keep the battery in a cool and dry place. Don't overcharge the battery. If you're not going to use the tool for a long time, remove the battery. And always store the tool in the provided carrying bag to protect it from damage.
