Using the Klein 630-9MM Nut Driver is easy. Simply select the right nut and place the driver's tip into the nut. Then, hold the cushion-grip handle firmly and turn it clockwise to tighten or counterclockwise to loosen. When working on long bolts or stacked circuit boards, the hollow shaft will come in handy. Just slide it over the bolt and get to work. As for maintenance, keep it clean and dry. Wipe it down after each use to prevent dirt and debris from building up. Avoid using it in extremely wet or corrosive environments. If it gets dirty, you can use a mild cleaner and a soft cloth to clean it. And remember, always store it in a safe place to avoid damage.
