Sanding tips
If the tool is connected to a vacuum dust extraction system, switch the extraction device
on before switching on the sander. Switch the sander off first, then the vacuum system
Move the machine in a circular motion over the workpiece surface, applying an even,
moderate pressure until you reach the desired surface finish
WARNING: Excessive pressure does not lead to a faster removal of material; it will however
lead to premature wear of the sanding sheet, and may cause damage to the machine.
If there are still scratches on your workpiece after sanding, refer to 'Selecting the right
grade of sanding sheet'
