Using this Pro Mini Performance Tool is easy. For basic tasks like turning screws, just pick the right bit - the PH2 screwdriver bit for regular screws or the Torx bits for specific types. When you need to work on a bike chain, use the 9 - 12 speed chain tool and the chain holder to keep things in place. The spoke wrenches are great for adjusting bike spokes. Remember to always handle the tool with care, especially the hardened steel bits as they can break if used forcefully on very hard materials. 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. If you notice any damage, stop using the tool and have it checked by a professional.
