Using this Klein Tools 4-inch adjustable wrench is easy. First, open the jaws by turning the knurl until they're wide enough to fit the nut or bolt you're working on. Then, place the jaws around the fastener and start turning the wrench. Make sure to keep a firm grip on the contoured, plastic-dipped handles for better control. When it comes to maintenance, wipe the wrench clean after each use to prevent dirt and debris from building up. The chrome-plated finish helps resist rust, but if you notice any signs of corrosion, you can use a mild metal cleaner. Store the wrench in a dry place to avoid damage. Also, don't use it for tasks beyond its jaw capacity, as this could damage the tool. With proper use and care, this wrench will serve you well for a long time.
