5. ALWAYS maintain a clearance of 1.5-2mm between the table and the
sanding belt or disc.
6. ALWAYS hold the workpiece firmly so that it cannot be pulled from your

7. ALWAYS feed the workpiece against the direction of rotation of the disc. i.e
the LEFT side of the disc.

DUST EXTRACTION
The sander is provided with a dust extraction facility. Please note however,
that this does not preclude the user from wearing a face mask to prevent the
inhalation of dust particles.
It is an EEC requirement that a dust extraction facility be provided on power
tools, however, due to the nature of the sander, some of the dust produced
will be forced into the surrounding atmosphere and will not be collected.
