Using the Milwaukee M12 FUEL 1/4 Extended Reach High - Speed Ratchet is quite straightforward. First, make sure the battery is properly inserted. You can choose to use it manually by not engaging the motor or switch it on to take advantage of the high - speed performance. When using it, keep the ratchet steady and apply appropriate pressure. In tight spaces, the extended neck will be very helpful. For safety, always wear appropriate protective gear like gloves. When it comes to maintenance, after each use, wipe the ratchet clean to remove any dirt or debris. Check the battery regularly and charge it as needed. Also, lubricate the moving parts occasionally to keep the ratchet working smoothly.
