Using your DeWalt DW8309 flap disc is easy. First, make sure your grinding tool is turned off and unplugged. Attach the disc to the tool following the manufacturer's instructions. When you start grinding, hold the tool at a 10 - 25 degree angle for the best results. This angle lets you use the whole disc and gets the job done efficiently. Remember to wear safety goggles and gloves to protect yourself from debris. As for maintenance, keep the disc clean after each use. Store it in a dry place to prevent rust and damage. If the disc starts to wear out unevenly or lose its cutting ability, it's time to replace it.
