Using the DeWalt DWE46125 is easy. First, adjust the shoe to set the cutting depth according to your needs. You can refer to the outer blade guide to ensure a precise cut. When you start and finish cutting, the plunging system will help collect dust effectively. Make sure to connect the hose to the hose port with the specified outer and inner diameters for proper dust extraction. As for maintenance, after each use, clean the dust shroud to keep it in good condition. Also, check the blade and the adjustable shoe regularly for any signs of wear. Store the tool in a dry place to prevent rust and damage. And always follow the safety instructions provided by DeWalt to avoid any accidents.
