Using this Milwaukee ratchet is easy. First, charge the battery using the included charger. Once charged, insert it into the tool. You can use the ratchet either with the motor engaged for high - speed operation or manually when you need more control. When working in low - light areas, turn on the LED light for better visibility. Check the on - board fuel gauge to know how much battery life is left. As for maintenance, keep the ratchet clean after each use. Wipe off any dirt or debris, especially if you've been working in a dirty or corrosive environment. Avoid overloading the tool, as REDLINK PLUS™ is there to protect it, but overloading can still reduce its lifespan. Store the ratchet in a dry place when not in use. And remember, this ratchet is part of the M12™ system, so you can swap batteries with other compatible tools in the system.
