Using the Klein Tools 68413 7/16 - Inch Combination Wrench is straightforward. For tight spots, use the open end with its 15 - degree offset. Place it on the nut or bolt and turn it as needed. The box end, also at a 15 - degree angle, is great when there are obstacles around. Just fit it over the nut and turn. When using, make sure to apply force steadily and in the right direction to avoid slipping. As for maintenance, keep it clean after each use. Wipe off any dirt or debris. Since it's nickel chrome plated and corrosion - resistant, it can handle normal conditions well. But if you use it in a very wet or harsh environment, dry it thoroughly to prevent any long - term damage. Store it in a dry place to keep it in good shape for future use.
