Using the DeWalt DWHT70263M hex key set is easy. First, choose the right size hex key for your job. Press the push - button to unlock the key and adjust it to the angle you need (90°, 135°, or 180°), then lock it in place. When using, make sure to apply force steadily to avoid slipping. After use, clean the keys with a dry cloth to keep them in good condition. Store the set in a dry place to prevent rust. If you notice any damage, stop using the key and replace it if necessary.
