Using the Klein Tools 3247 round bar is easy. When you're working on positioning steel members and aligning bolt holes, hold the bar firmly and use the pointed end to get into tight spaces. The 15 - degree angled chisel - end can be used to apply extra leverage. Just place it against the surface and push or pull as needed. As for maintenance, after each use, wipe the bar 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, away from moisture. Always wear appropriate safety gear like gloves and goggles when using this tool to avoid any injuries.
