Using the 1/2 - inch QuickCut™ Tubing Cutter is a breeze. First, locate the tubing you need to cut. Then, with one hand, clip the cutter onto the tube. Start rotating the cutter around the tube, and it will smoothly cut through. It's designed to work great in tight spots, so don't hesitate to use it in confined areas. One important thing to note is that when replacing the SXT™ Cutting Wheel (Part 42526), make sure to follow the correct installation steps. For maintenance, keep the cutter clean and dry. The stainless - steel rollers ensure long - lasting performance, but regular checks are still recommended to make sure everything is in good working order. With proper use and care, this cutter will serve you well for a long time.
