Using an orbital sander is a simple process. Ensure you have the correct grit for the type of surface you’re sanding and attach the sandpaper to the face of the sander. Secure the piece you’re sanding to a sturdy surface, using clamps if necessary, and put on your personal protective equipment (PPE). Firmly hold the sander (it can jump from your hand), turn it on, allowing it to reach full speed before applying it to the surface, and let the sander glide across the surface without bearing down. When finished, turn the sander off and remove the sandpaper. Attaching a ventilation system to your sander will prevent heavy sawdust messes.
