Using this GearWrench 89078 tool set is a breeze. First, pick the right tool for the job. If you're dealing with SAE fasteners, look for the double - lined markings. For metric ones, find the knurled - lined. When using the ratchets, just flip the on/off lever to change the direction. The universal joints are great for those hard - to - reach spots. Just attach them to the socket or wrench. When working with the extension bars, hold onto the knurled part for a good grip. As for the combination wrenches, the 15° offset box end gives you more space for your knuckles. When it comes to maintenance, after each use, wipe the tools clean with a dry cloth. If they get dirty, you can use a mild soap and water. Make sure to dry them thoroughly to prevent rust. Store the tools in a dry place, and try to keep them organized in the set. Don't use the tools for jobs they're not designed for, as this can damage the fasteners and the tools themselves.
