Using your Milwaukee 2552 - 20 M12 FUEL Stubby 1/4 Impact Wrench is easy. First, make sure the M12 REDLITHIUM battery is properly installed. Select the appropriate mode on the 4 - Mode Drive Control according to your task. For precise work, use the 1 - 3 RPM setting. When reassembling, the Auto - Shut Off Mode can be very helpful to avoid over - tightening. When removing stubborn bolts, the high breakaway torque of 100 ft. - lbs. will do the job. As for maintenance, keep the tool clean and dry. After use, store it in a cool and dry place. Periodically check the battery and the motor for any signs of wear or damage. If you notice any issues, it's best to contact Milwaukee's customer service for assistance.
