Using the Milwaukee M12 FUEL™ 1/4 High Speed Ratchet is straightforward. First, make sure the battery is fully charged. You can check the battery's remaining power using the on - board fuel gauge. If you need to work in a dark area, turn on the LED light. You can operate the ratchet in two ways: use it manually by not engaging the motor, or use it as a power tool. The extended paddle switch gives you different grip options, so find the one that's most comfortable for you. When using it, avoid overloading the tool as the REDLINK PLUS™ Intelligence is there to protect it, but overloading may still reduce its lifespan. As for maintenance, keep the tool clean, especially after using it in a dirty or corrosive environment. The durable rubber on the tool can withstand corrosive materials, but it's still a good idea to wipe it down. Regularly check the steel yoke housing for any signs of damage. Store the tool and its battery in a cool, dry place. And since it's part of the M12™ system, you can swap batteries with other compatible tools in the system.
