Using the Makita A-69048 Grinding Wheel is easy. First, make sure you have the Makita Blade Sharpener model 98202. Install the grinding wheel on the sharpener according to the sharpener's instructions. Then, you can start sharpening your blades, knives, or scissors. Just hold the item steadily against the spinning wheel at the right angle. When using the wheel, always wear safety goggles to protect your eyes from any flying debris. Also, don't exceed the maximum speed of 1,200 RPM. After each use, turn off the sharpener and let the wheel stop completely before handling it. To keep the wheel in good condition, clean it regularly with a soft brush to remove any debris. Store it in a dry place to prevent rusting. If you notice any signs of damage or excessive wear, replace the wheel for safety and optimal performance.
