Using the Milwaukee 48 - 53 - 2564 drain cable is easy. First, make sure your drain machine is turned off. Then, connect the cable to the machine. Feed the cable into the drain slowly and steadily. When you feel resistance, use the machine's power to work the cable through the blockage. As you use it, watch for the end - of - cable indicator, which is about 3 feet from the back end, to avoid over - extending. After use, clean the cable with a brush and water to remove any debris. Store it in a dry place to prevent rust. Remember, this cable is covered by a 2 - year warranty, but handle it with care to avoid breakage or defects.
