Using your Klein Tools 68234 ratcheting box wrench is a breeze. First, pick the right end size for your bolt. If you need to change the direction of the ratchet, just flip the quick - flip lever. It's perfect for those hard - to - reach spots because of the 25 - degree offset ends. When using it on long bolts, the open sockets work really well. As for maintenance, keep it clean after each use. Wipe off any dirt or debris. Since it has a chrome - plated finish, it's resistant to rust, but if you notice any signs of rust starting, you can use a mild metal cleaner. Store it in a dry place to keep it in good shape. Also, don't use it for jobs it's not designed for, as the laminated construction, while strong, has its limits.
