Using the Milwaukee 2567-20 M12 FUEL™ 3/8 High Speed Ratchet is easy. First, make sure the battery is fully charged or properly installed. To start, just use the extended paddle switch for a comfortable grip. You can use it at high - speed for quick work or rely on its high torque for stubborn nuts and bolts. If you're in a tight space, its compact head profile will give you the access you need. The LED light is handy when working in dark areas, just turn it on to see clearly. You can also use the ratchet manually if you prefer. When it comes to maintenance, keep the tool clean. Wipe it down after each use, especially if it's been exposed to corrosive materials. Check the battery regularly and charge it as needed. Avoid overloading the tool as the REDLINK PLUS™ Intelligence is there to protect it, but overloading can still reduce its lifespan. Store the tool in a dry place and it will serve you well for a long time.
