Using the DeWalt DWA8959F is easy. First, make sure your cutting machine is turned off and unplugged. Then, carefully install the wheel onto the arbor of your cutting tool, following the tool's instructions. Once it's securely in place, you're ready to start cutting. When using the wheel, keep a steady hand and apply even pressure. This will help you get a smooth and straight cut. For best results, use the wheel on metals like rebar, heavy - wall pipes, and sheet metal. When it comes to safety, always wear safety goggles to protect your eyes from flying debris. Also, use ear protection as the cutting process can be quite noisy. Make sure the work area is well - ventilated to avoid inhaling any dust. For maintenance, after each use, let the wheel cool down completely. Then, you can use a soft brush to clean off any metal shavings or debris. Store the wheel in a dry place to prevent rusting. If you notice any signs of damage or wear, replace the wheel right away to ensure safe and efficient cutting.
