Using this Milwaukee screwdriver is easy. First, make sure the battery is fully charged. Insert the bit into the 1/4" hex quick-change chuck with one hand. Then, select the appropriate speed setting depending on your task. For more precision, use the low speed (0-400 RPM), and for faster work, switch to the high speed (0-1,500 RPM). The LED light can be very useful when working in dark areas. When not in use, store the screwdriver in the carrying case to protect it. Keep the battery in a cool, dry place. After each use, wipe the tool clean. Check the bit for wear and replace it if necessary. Remember, the tool has a 5-year warranty, but taking good care of it will ensure it lasts even longer.
