Using the Klein Tools 3222 spud wrench is straightforward. First, identify the 3/4 - Inch bolts or U.S. regular nuts you need to work with. Then, place the 1 - 1/8 - Inch nominal opening of the wrench over the nut or bolt head. Thanks to the tapered handle, you can easily align the bolt holes. Just turn the wrench to tighten or loosen. When using it, avoid applying excessive force beyond what the wrench is designed for, as it could damage the tool. After each use, wipe it clean with a dry cloth to prevent rust. Store it in a dry place. If it gets dirty, you can use a mild soap and water solution to clean it, but make sure to dry it thoroughly afterward.
