Using your Milwaukee drain cable is easy. First, make sure your drain machine is compatible with this cable. Connect the cable to the machine, and then slowly feed it into the drain. As you go, use the cable's strong pull force to break through blockages. When you're done, don't forget to check the end - of - cable indicator to know when you're close to the end. Regarding maintenance, after each use, clean the cable to prevent debris build - up. Since it has RUST GUARD plating, it's quite resistant to rust, but it's still a good idea to store it in a dry place. If you notice any signs of damage or breakage, contact Milwaukee as the cable is covered by a 2 - year warranty. Also, be careful when handling the cable to avoid kinks, as the controlled torque helps but extreme bending can still cause issues. And when swapping attachments, do it gently to maintain the cable's flexibility.
