DUST/ChIp EXTRACTION
f
Dusts from materials such as lead-containing coat-
ings, some wood types, minerals and metal can be
harmful to one’s health. Touching or breathing-in
the dusts can cause allergic reactions and/or lead
to respiratory infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are consid-
ered as carcinogenic, especially in connection with
wood-treatment additives (chromate, wood preser
-
vative). Materials containing asbestos may only be
worked by specialists.
As far as possible, use a dust extraction system
suitable for the material.
Provide for good ventilation of the working place.
It is recommended to wear a P2 filter-class respi
-
rator.
Observe the relevant regulations in your country
for the materials to be worked.
f
prevent dust accumulation at the workplace.
Dusts can easily ignite.
EXTERNAL DUST EXTRACTION
Mount a vacuum hose onto the extraction out
-
let
10
. Connect the vacuum hose with a vacuum
cleaner. An overview for the connection of vari
-
ous vacuum cleaners can be found at the end of
these instructions.
The vacuum cleaner must be suitable for the ma
-
terial being worked.
When vacuuming dry dust that is especially det
-
rimental to health or carcinogenic, use a special
vacuum cleaner.
INTEGRATED DUST EXTRACTION wITh DUST
BAG
for small sanding jobs, a dust bag
7
(accessory)
can be connected. Attach the sleeve of the dust
bag firmly onto the outlet piece
10
. To maintain
optimum dust collection, empty the dust bag
7
in
good time.
ChANGING ThE SANDING BELT
Completely pivot out the clamping lever
3
. The
sanding belt
2
is now loose and can be removed.
Mount the new sanding belt
2
. Pay attention that
the direction of the arrows on the inside of the
sanding belt correspond with the arrow direc-
tion on the machine housing.
Pivot the clamping lever
3
back to its initial posi-
tion.
Pick up the power tool and switch it on. Adjust the
belt run with adjustment knob
9
until the edge
of the sanding belt runs flush with the guide
plate
13
.
Pay attention that the sanding belt
2
does not
move excessively and make contact with the
housing. Check the belt run regularly and readjust
with the adjustment knob
9
.
OpERATION
STARTING OpERATION
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine. pow
-
er tools marked with 230 v can also be operated
with 220 v.
SwITChING ON AND OFF
To
start
the machine, press the On/Off switch
5
and
keep it pressed.
To lock the
pressed
On/Off switch
5
, press the lock-
on button
6
.
To
switch off
the machine, release the On/Off
switch
5
or when it is locked with the lock-on button
6
, briefly press the On/Off switch
5
and then release
it. To save energy, only switch the power tool on
when using it.
pRESELECTING ThE BELT SpEED
The necessary belt speed can be preselected with
the thumbwheel
4
, even during operation.
The required belt speed depends on the material
being sanded and on the working conditions, and
can be determined by practical testing.
wORkING ADvICE
The sanding removal rate and the surface quality
are mainly determined by the selection of the sand-
ing belt as well as by the preselected belt speed. The
higher the belt speed, the more material is removed
and the finer the sanded surface.
Only flawless sanding belts achieve good sanding
capacity and make the machine last longer.
Work using the least possible sanding pressure in or-
der to increase the service life of the sanding belts.
The machine’s own weight is sufficient for a good
sanding performance. An excessive increase of the
sanding pressure does not lead to an increase of the
sanding capacity, but to increased wear of the ma-
chine and the sanding belt.
Apply the machine to the workpiece only when
switched on. Work with moderate feed and car-
ry out the sanding with parallel and overlapping
strokes. Sand in the direction of the grain; sanding
across the grain produces an uneven sanding effect.
Particularly when sanding coats of varnish, sand in
the direction of the grain as the varnish could melt
and smear the surface of the workpiece and the
sanding belt. Therefore, work with dust extraction.
A sanding belt used for sanding metal should not be
used for other materials.
Store sanding belts only hanging; avoid creasing, as
this makes the belts unusable.
The sanding frame (accessory) allows for uniform
and controllable removal capacity when surface
grinding larger wooden surfaces.
