Using the Milwaukee M12 FUEL 1/2-inch ratchet is easy. First, if you have a compatible REDLITHIUM battery, insert it into the tool. Then, select the appropriate socket for your job and attach it to the ratchet. You can control the speed of the ratchet using the variable - speed metal trigger. Just squeeze it gently for slower speeds and more firmly for faster speeds. When working in low - light areas, use the LED light to illuminate your work area. The on - board fuel gauge will tell you how much battery life is left. As for maintenance, after each use, wipe the tool clean with a dry cloth to remove any dirt or debris. Make sure to store the tool in a dry place. If you notice any unusual noises or the performance of the tool is decreasing, stop using it and have it checked by a professional. Also, always use the tool with the recommended REDLITHIUM batteries and follow the safety instructions provided in the user manual.
