Using the Makita A - 95984 - 5 grinding wheels is easy. First, make sure your 4 - 1/2' angle grinder is turned off and unplugged. Then, securely attach the grinding wheel to the grinder following the manufacturer's instructions. When you're ready to start grinding, hold the grinder firmly and apply light pressure. Let the wheel do the work. You'll notice it removes material quickly due to its 36 - grit abrasive. When working with stainless steel, the 'N' grade hardness of the wheel is just right. Be aware that even though the wheel is designed to reduce noise and vibration, it's still a good idea to wear ear protection and safety goggles. After each use, unplug the grinder and store the wheel in a dry place. Don't expose it to extreme temperatures or moisture. If the wheel shows signs of excessive wear or damage, replace it right away to ensure safe and efficient operation.
