Using your Milwaukee 48 - 53 - 2684 1 - foot C - Cutter with Rustguard is a breeze. First, make sure it's properly attached to your drain machine, either a Milwaukee® one or other professional cleaners. Then, gently feed the cable into the drain. As you use it, the unique cable wind geometry and small connecting points will help it move smoothly through the pipes. When you're about 3 feet from the end of the cable, the indicator will let you know. To avoid issues, don't apply too much force that could cause the cable to break or kink. The controlled torque is there to help, but it's still good to be careful. After each use, clean the cable to prevent debris build - up. Store it in a dry place to maintain the rust protection. And remember, it comes with a 2 - year warranty, so if you have any problems with defects or breakage, you're covered.
