Using this Milwaukee leader cable is easy. First, make sure your drain cleaning machine, like the MX FUEL™ Sewer Drum Machine (MXF500 or MXF501), is turned off. Then, connect the cable to the machine using the interlocking cable connectors with pin - key release. Once connected, turn on the machine and slowly feed the cable into the drain. Let the industrial steel spring do its job to break up clogs. When you're done, turn off the machine and carefully pull the cable out. As for maintenance, after each use, clean the cable with a mild detergent and water to remove any debris. Check the stainless - steel release pin and spring regularly for any signs of wear. Store the cable in a dry place to prevent rust. And remember, this cable comes with a 2 - year warranty, so if you have any issues, reach out to Milwaukee.
