Using your Milwaukee 2649-20 M18 Orbital 1/4 Sheet Sander is a breeze. First, make sure your 18V Lithium - Ion battery is fully charged. Then, use the two - step clamp system to attach the sandpaper quickly. Turn on the sander using the on - off switch, and you can lock it on for continuous operation. Adjust the variable speed dial according to the material you're working on. For softer materials, you might want to use a lower speed (11K OPM), and for tougher ones, go for the higher 13K OPM. When it comes to dust collection, connect either the included dust bag or use the universal hose adapter to your vacuum. This will keep your workspace clean. As for maintenance, after each use, empty the dust bag. Check the sandpaper for wear and replace it when it's no longer effective. Also, keep an eye on the battery. Don't over - discharge it, as REDLINK Technology is there to protect it, but it's still good practice. Store the sander in a dry place to prevent any damage.
