Using the DeWalt DWA4213 blade is easy. First, make sure your oscillating tool is turned off. Then, attach the blade to the tool following the tool's instructions. Since it has a universal fit, you won't need an adapter for most major brands. When you're ready to cut, start with a slow speed and gradually increase it as needed. This blade is great for cutting wood with nails, but be careful not to put too much pressure on it. After use, clean the blade with a dry cloth to remove any debris. Store it in a dry place to prevent rusting. If you notice the blade is getting dull, it might be time to replace it for the best cutting performance.
