5.2 Sanding Techniques
For best results and to prolong the life of your sander:
- Always allow the sander to reach full speed before applying it to the workpiece.
- Apply light, even pressure. Excessive pressure will not speed up sanding and can damage the tool or workpiece.
- Move the sander in smooth, overlapping passes across the surface.
- Ensure the entire sanding pad is in contact with the surface.
- For fine finishing, use finer grit sandpaper and reduce pressure.
