Using the GearWrench 86247 wrench set is a breeze. First, pick the right-sized wrench for your fastener. The color-coded size markings make it easy to find the one you need. Place the wrench on the fastener and start turning. Thanks to the 3-degree swing arc, you can work in tight spots. The flexible head is great for reaching those hard-to-get bolts. When using it, make sure the wrench is fully seated on the fastener to avoid rounding. As for maintenance, after each use, wipe the wrenches clean with a dry cloth. The chrome finish resists corrosion, but it's still a good idea to keep them dry. Store the wrenches in the included rack to keep them organized and prevent damage. Remember, this set comes with a limited lifetime warranty, so if you have any issues, you're covered.
