5.1 General Sanding Techniques
- Secure your workpiece to prevent movement during sanding.
- Hold the sander firmly with both hands.
- Switch on the sander before making contact with the workpiece.
- Apply even, moderate pressure and move the sander smoothly across the surface in the direction of the wood grain. Avoid tilting the sander or applying excessive pressure, which can cause gouging or uneven sanding.
