Using the Milwaukee 2567-20 M12 FUEL™ 3/8 High Speed Ratchet is easy. First, make sure the battery is fully charged. You can use it with the motor engaged for power or manually when needed. When using it in tight spaces, the 0.75-inch head profile will come in handy. The LED light can be turned on to illuminate your work area. For different tasks, take advantage of the multiple grip options offered by the extended paddle switch. As for maintenance, keep the tool clean after each use. Wipe off any dirt or debris, especially if it's been exposed to corrosive materials. Check the battery regularly and store it in a cool, dry place. If the tool starts to overheat or shows any signs of trouble, turn it off immediately. Thanks to REDLINK PLUS™ Intelligence, the tool and battery are protected from overloading and overheating, but it's still good to be cautious.
