SANDING PROCEDURE
With the sander switched on, bring it into contact with the workpiece and move it forward carefully.
Continue sanding using overlapping strokes parallel to the belt track. Always work in the direction of
the grain to avoid undesirable transverse sanding marks.
VACUUM EXTRACTION OF DUST
Wear a dust mask! Vacuum extraction of dust makes disposal easier, prevents the build up of
stubborn dust deposits and keeps dust out of the air you are breathing. It will also prevent sanding
debris from getting on to the workpiece surface and leaving grease or burn marks.
Pull the dust collection bag
µ over the supplied adapter and attach it to the dust extraction spout ¶ .
The stirrup-shaped adapter ensures that the dust collection bag is fully opened out to accept the
sanding dust (see Fig.
ቤ ). Empty the dust collection bag regularly.
You can also attach a domestic vacuum cleaner to the dust extraction spout ¶ (see Fig. ብ ). Do not
use the domestic vacuum cylinder to extract an explosive mixture of dust and air.
If there is an explosive mixture of dust and air you must use a vacuum device especially intended for
that purpose.
ATTENTION - DANGER OF FIRE: Do not use vacuum dust extraction (dust bag or vacuum cleaner)
when sanding metals (flying sparks).
NOTE
• Always move the belt sander over the workpiece surface with both hands using even movements.
• The auxiliary handle
³ can be adjusted or removed to allow you to sand those difficult-to-reach
places.
SELECTING BELT SPEED AND SANDING SHEET
You can select the belt speed using the belt speed selector wheel » , even whilst the sander is
running. The optimum belt speed depends on the workpiece and the workpiece material. Always
confirm the best speed by carrying out a small test. The following table lists some recommended
values to help you determine the optimum speed.
Material / type of work Coarse sanding (grit) Fine sanding (grit) Speed
Softwood 0 60 240 high (5-6)
Hardwood 0 60 180 high (5-6)
Plywood 0 60 150 high (5-6)
Removing paint/varnish 0 60 –– high (5-6)
