Using your PerformaX Shoppro 25 Drum Sander is easy. First, make sure to read the included manual thoroughly. Place the sander on a flat and stable surface. When sanding, feed the wood through the sander at a steady pace. Avoid pushing too hard as it might damage the sandpaper or the sander itself. Always wear safety goggles and a dust mask to protect yourself from dust. For maintenance, clean the sander regularly after use. Check the sandpaper for wear and replace it when it gets dull. Also, keep an eye on the moving parts and lubricate them as needed. Since this is a used item, just give it a bit of extra care to keep it running smoothly.
