Using the DeWalt DW2221B magnetic nut driver is easy. Just pick up the tool and align the bit with the nut you want to turn. The strong magnet will hold the bit firmly, so you can start turning the nut right away. When using it, make sure to apply steady pressure to avoid stripping the nut. As for maintenance, keep the tool clean after each use. You can wipe it with a dry cloth to remove any dirt or debris. Store it in a dry place to prevent rusting. If you notice the magnet getting weaker over time, it might be a sign to replace the tool. With proper use and care, this nut driver will serve you well for a long time.
