by moving the tensioning lever 9 fully outwards . The
tensioner is now open and the sanding belt can be re-
moved.
2. Next insert a new sanding belt or change the belt
for one suitable for a different material or one with a
different grit size.
Important : The direction of the arrows on the inside
of the sanding belt must agree with that on sander
housing.
3. Press the tensioning lever 9 back into its initial po-
sition.
Adjusting the sanding belt:
Pick up the device, switch it on and turn it over.
Adjust the belt tracking by turning the adjuster screw 6
until the edge of the sanding belt is flush with and runs
parallel to the edge of the device.
Important : Always make sure that the sanding belt
does not cut into the housing.
Check the sanding belt regularly and if necessary re-
-adjust it using the adjuster screw 6 .
Advice on use
Light sanding pressure is enough:
Apply light sanding pressure only. The weight of the
belt sander alone is adequate to produce good san-
ding results. By adopting this approach you will also
prolong the life of your sanding belts and obtain a smo-
other workpiece surface.
Sanding and surfaces:
The sanding output and the quality of the surface fi-
nish obtained are determined by the belt speed and
the grade of grit on the sanding belt (see the section
on "Selecting the correct rotational speed and sanding
belt").
Sanding procedure:
With the sander switched on, bring it into contactwith
the workpiece and move it forward carefully. Work in
parallel and overlapping widths. Always work in the
direction of the grain to avoid undesirable transverse
sanding marks.
After sanding always lift the device from the workpiece
before switching it off.
Vacuum dust extraction
Danger of fire! There is the danger of fire when working
with electrical devices that have a dustbox or can be
connected to a vacuum cleaner. Under certain condi-
tions the wood dust in the dust collection box (or in the
vacuum' s dust bag) may self-ignite, e.g. as a result of
flying sparks generated when abrading metals or metal
objects left in wood. This can happen particularly if the
wood dust is mixed with paint residue or other chemi-
cals and the abraded particles are hot from prolonged
abrasion. Therefore you must empty the device's dust
collection box and the vacuum cleaner's dust bag be-
fore taking a break or stopping work and always avoid
overheating of the abraded particles and the device.
Wear a dust mask!
Dust extraction using the dust collection box:
Slide the dust collection box 10 on to the dust
extraction spout 5 on the side of the device .
Emptying the dust collection box:
Pull the dust collection box 10 off the dust extraction
spout 5 . Open the dust collection box 10 and empty it.
Dust extraction using external vacuum extraction:
If there is an explosive mixture of dust and air you must
use a vacuum device especially intended for that pur-
pose.
Danger of fire! Do not use vacuum dust extraction
(dust collection box or vacuum cleaner) when sanding
metals (flying sparks).
1. Push the extraction adapter on to the dust extrac-
tion spout 5 on the side of the device .
2. Slide the hose of a suitable dust extraction device
approved for that purpose (e.g. a workshop vacuum
cleaner) on to the extraction adapter .
Operation
Switching on and off
The belt sander has full-wave electronics with addi-
tional control electronics, soft start with inrush current
limiting.
When operating the belt sander you can select
between intermittent or continuous operation mode.
For short sanding tasks use the intermittent operation
mode. For longer sanding tasks we recommend the
continuous operation mode. Whilst working in your
selected mode the device functions as follows:
To switch on intermittent operation mode:
Press the ON / OFF switch 3 .
To switch off intermittent operation mode:
Release the ON / OFF switch 3 .
To switch on continuous operation mode:
Press the ON / OFF switch 3 , and keep it
pressed, then press the locking knob 2 .
To switch off continuous operation mode:
Press and then release the ON / OFF switch 3 .
Selecting the correct rotational speed and sanding belt
You can select the belt speed using the belt speed ad-
juster wheel 1 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.
Using the sander in a fixed mounting
The fixed mounting kit allows you to use the device
for sanding vertically or horizontally by fastening
it on to a flat stable surface (e.g. workbench).
Tips and tricks
Never use the same sanding belt to sand wood and
metal.
Worn or ripped sanding belts can damage the workpie-
ce. Change sanding belts at the appropriate time.
Keep the sanding belt properly tensioned so that it
does not hang down too much and become unusable
due to nicks, creases etc.
