Using the Klein Tools 507-10 adjustable wrench is easy. First, adjust the knurl to open or close the jaws to fit the size of the nut or bolt you're working on. Once it's the right size, place the jaws around the fastener and turn the wrench in the direction you need to loosen or tighten. When using it in confined spaces, the extra capacity really comes in handy as you can use a smaller wrench for bigger jobs. For maintenance, after each use, wipe the wrench clean with a dry cloth to remove any dirt or debris. If it gets wet, dry it thoroughly to prevent rust. Store it in a dry place. Be careful not to use it for jobs that are beyond its capacity as it could damage the tool. Also, avoid dropping it on hard surfaces as this might affect the precision of the jaws.
