Adjusting Variable Speed
The variable-speed dial allows you to adjust the sanding speed from 8,000 to 12,000 OPM. Rotate the dial to select the appropriate speed for your material and application. Lower speeds are suitable for delicate work or finishing, while higher speeds are for aggressive material removal.

Sanding Techniques
- Always hold the sander firmly with both hands.
- Allow the sander to reach full speed before applying it to the workpiece.
- Apply light, even pressure. Do not press down excessively, as this can reduce sanding efficiency and damage the workpiece or tool.
- Move the sander in overlapping circular or back-and-forth motions for even material removal.
- For best results, sand with the grain of the wood where possible.
