The TEENO sander is suitable for various applications, including rust removal, wood sanding, furniture finishing, and sanding corners/edges.

• General Sanding: Hold the sander firmly with one hand, ensuring the sanding pad is flat against the surface. Move the sander in smooth, overlapping passes. Avoid applying excessive pressure, as the tool's weight is usually sufficient.
