Using the Klein Tools 3245 Round Connecting Bar is straightforward. When you need to position steel members or align bolt holes, simply insert the bar into the appropriate places. The pointed end can be used to start the alignment process, and the chisel - end with its 15 - degree angle gives you that extra push for better leverage. As for maintenance, after each use, clean the bar with a dry cloth to remove any dirt or debris. Store it in a dry place to prevent rusting. Always wear appropriate safety gear like gloves and goggles when using this bar. If the bar shows signs of excessive wear or damage, it's best to replace it for safety reasons.
