Follow the basic machine tool safety protocol: safety glasses, long pants, closed toe shoes, no loose clothing, jewelry or hair that may get caught in the moving machine
Workpiece must be supported on the machine table so that it is not pulled out of your hand.
Only sand on the downward-moving half of the disk sander where friction pushes the workpiece into the table.
Connect a vacuum to the sander if you will be generating a lot of dust.
Friction may heat workpiece to high temperatures - be careful not to touch hot surfaces.
Keep body parts clear of sandpaper. Use a tool to hold small parts.
Don’t wear bracelets, dangling articles of clothing, gloves or long sleeves while using the sander.
