Using the DeWalt DWA4216 oscillating tool accessory set is easy. First, pick the right blade for your job. If you're cutting wood with nails, use the dedicated wood - with - nails blade. For a fast cut in wood, go for the fast - cut wood blade. The flush - cut blade is great for precise trimming, and the rigid scraper blade can handle scraping tasks. When installing the blade on your oscillating tool, make sure it fits securely according to the tool's instructions. Remember, since these blades have universal fitment, they should work well on most major brand oscillating tools without an adapter. As for the ToughCase, take advantage of its customizable compartments. You can arrange the blades however you like to keep things organized. When it comes to maintenance, after each use, clean the blades with a brush to remove any debris. Store the blades in the ToughCase to protect them from damage. Also, check the blades regularly for signs of wear and tear. If a blade is too dull or damaged, replace it to ensure the best performance of your oscillating tool.
