Using your Milwaukee 48 - 53 - 2787 Medium Drop Head with Rustguard is easy. First, make sure it's compatible with your drain machine. Then, insert the cable into the drain. The unique cable wind design and small - diameter connecting points help it move smoothly through the pipes. When you're done, pull it out gently. Be careful not to over - torque the cable as the controlled torque feature is there to limit breakage and kinks. After each use, clean the cable to keep it in good condition. Check the end - of - cable indicator regularly to know when you're getting close to the end of the cable. Store it in a dry place to maintain the rust - guard feature and extend its lifespan. If you have any issues, remember it's backed by a 2 - year warranty.
