Using the Milwaukee M12 FUEL 1/4 Extended Reach High-Speed Ratchet is easy. First, make sure the battery is properly inserted. You can use it manually without turning on the motor if needed. To use it powered, just pull the variable speed metal trigger. The higher you pull, the faster it will run, giving you great control. When working, remember to wear safety goggles to protect your eyes. Don't overload the tool. The maximum torque is 35 ft-lbs, so don't try to use it for jobs that need more force. For maintenance, keep it clean after each use. Wipe off any dirt or debris. Store it in a dry place. Also, if the battery runs low, charge it right away. The POWERSTATE brushless motor is durable, but following these steps will keep your ratchet in great shape for a long time.
