Using the DeWalt DWAF2053 16 - Piece Magnetic Drive Guide Set is a piece of cake. First, open the ToughCase®+ using the clip latch. The clear lid makes it easy to find the bit you need. Simply remove the bit from the patented bit - bar design. When you're done, put the bit back in its place for easy organization. As for the magnetic drive guide, use it to hold the bit firmly in place while you're working. Here are some things to keep in mind. Don't force the bits when removing or inserting them into the bit - bar to avoid damage. Make sure the clip latch is properly closed to keep the contents secure. For maintenance, wipe the bits and the case with a dry cloth after use. If there's any dirt or debris, you can use a mild cleaner. Store the set in a dry place to prevent rusting of the S2 steel bits. And if you have other ToughCase®+ products, you can connect this set to them to save space and keep everything organized.
