Using your Makita cut-off wheel is straightforward. First, make sure your metal cutting power saw, whether it's bench-style or gas-powered, is turned off and unplugged. Then, carefully install the 14-inch wheel onto the saw, following the saw's instructions. When you're ready to cut, put on safety goggles and gloves. Turn on the saw and let it reach full speed before making contact with the metal. Move the saw steadily through the metal for a clean cut. As for maintenance, after each use, clean the wheel to remove any metal debris. Store the wheels in a dry place to prevent rust. If you notice the wheel is wearing out or damaged, replace it right away to ensure safety and good cutting performance.
