For installation, place the tool on the bottom bracket and turn it clockwise until the bracket is firmly in place. For removal, turn it counterclockwise. When using the tool, avoid applying too much force suddenly as it might damage the bracket or the tool. After each use, clean the tool with a dry cloth to keep it in good condition. Store it in a dry place to prevent rusting.
