Using the Makita A - 97592 blade is easy. First, make sure your 14 - inch metal cutting saw is turned off. Install the blade securely according to the saw's instructions. When you're ready to cut, hold the saw firmly and start it. Guide the saw slowly through the ferrous metal for a smooth cut. As for maintenance, after each use, clean the blade with a soft brush to remove any metal shavings. Store it in a dry place to prevent rust. Also, always wear safety goggles and gloves when using this blade. If the blade starts to cut less efficiently, it might be time to replace it.
