Using the Klein 3213TT erection wrench is straightforward. First, identify the 7/8 - Inch bolts or U.S. heavy nuts you need to work on. Then, use the wrench's head to grip the nut. Thanks to the continuous taper of the handle, it's easy to line up the bolt holes. When working at heights, don't forget to use the built - in hole to tether the tool for safety (you'll need to provide your own tether). As for maintenance, keep the wrench clean after each use. You can wipe it down with a dry cloth. If it gets dirty, use a mild detergent and water, then dry it thoroughly. Store it in a dry place to prevent rusting. And always check the stamped information on the wrench to make sure you're using it for the right bolt and nut sizes.
