Using the Klein Tools 3219 Spud Wrench is easy. First, identify the right size of the bolt and nut you're working with. The wrench is marked with the bolt size and nominal opening size, so just match it up. Then, place the wrench over the nut and turn it as needed. For lining up bolt holes, use the tapered handle to slide it in smoothly. When it comes to maintenance, keep it clean after each use. Wipe off any dirt or debris with a dry cloth. You can also apply a light coat of oil to prevent rust. Just a few drops on the metal parts and wipe it evenly. As for safety, always make sure you're using the wrench on the right size of bolts and nuts. Don't use excessive force that could damage the wrench or cause injury. And store it in a dry place when not in use to keep it in good condition.
