Using the Makita B - 10849 is easy. First, make sure your 14' cut - off saw is turned off and unplugged. Then, install the 14' abrasive cut - off wheel onto the saw following the saw's instruction manual. When you're ready to cut, start the saw and let it reach full speed before making contact with the ferrous metal. Move the saw steadily through the metal for a clean cut. Always wear safety goggles and gloves when using this blade. After each use, clean the blade with a soft brush to remove any metal shavings. Store the blade in a dry place to prevent rusting. If the blade becomes dull or damaged, replace it immediately for safe and efficient operation.
