Using these Metabo aluminum cutting wheels is quite straightforward. First, make sure your cutting tool is turned off and unplugged. Select the appropriate wheel type - Type 1 for flat cuts and Type 27 for cuts that need a bit more stability. Install the wheel on your tool following the manufacturer's instructions. When cutting, apply steady pressure and let the wheel do the work. Don't force it too hard as this can cause the wheel to wear out faster or even break. After use, clean the wheel gently with a soft brush to remove any debris. Store the wheels in a dry place away from moisture and extreme temperatures to keep them in good condition. Always wear safety goggles and gloves when using these cutting wheels to protect yourself from flying debris.
