Using the CBP - 8 tool set is a breeze. First, identify whether you're working on an Ultra - Torque™ or Power Torque™ system. For removing bearings, use the appropriate bearing puller. When taking out the crank, pick the right crank puller according to the system. The bearing setter helps you install the bearings correctly. Remember to use the protection pads with carbon cranks and the protection adaptor with aluminum crank arms to prevent damage. When using the crank removal extension plug for Power Torque™, make sure it's properly inserted. As for maintenance, after each use, clean the tools with a dry cloth to remove dirt and grease. Store them in a dry place to prevent rusting. If any parts seem worn out, it's a good idea to replace them to keep the tool set working effectively.
