Sandpaper
Selection
1. The grain size of the sandpaper is specified on
its rear side. The smaller the specified number,
the coarser the graining.
2. Use sandpaper with coarse grain for rough grind-
ing, and sandpaper with fine grain for finishing.
We recommend sandpapers with aluminium ox-
ide, silicon carbide or other synthetic abrasives.
3. lf you can chose between sandpapers with differ-
ent graining, you should start with coarse grain-
ing sandpaper and complete the grinding process
with the finest possible graining. Thus you will get
good and smooth grinding results.
How to apply and replace sandpaper
Apply the sandpaper (13) to the grinding plate (9) us-
ing the Velcro strip mechanism.
1. Align the sandpaper (13) with the grinding plate
(9) and press it on evenly.
2. PuII the sandpaper (13) off the grinding plate (9)
and replace it with a new one / another one (fig.
5).
Dust extraction
WARNING! Harmfull noxious gases may be gen-
erated when e.g. lead-containing paint is pro-
cessed. These gases entail a risk for the opera-
tor and the persons in the vicinity!
Therefore only use the power tool in combination
with a dust extraction unit, and protect yourself
and other persons in the working area with ad-
ditional suitable personal protective equipment!
When working with this power tool, a Iot of dust is
generated. The dust extraction unit is very useful if
you want to keep your workplace clean. lt is possi-
ble to combine the extraction system or a vacuum
cleaner with the extraction hose (11) which is con-
nected to the adapter for dust extraction.
1. Align the nose at the hose end with the extraction
hose adapter (12) (fig. 3), insert the end and secure
it by turning in a clockwise rotation (fig. 7).
2. Connect the dust extraction adapter with a suitable
dust extraction unit such as a vacuum cleaner (fig.
8).
Note: Make sure that the vacuum cleaner is suitable
for being used together with a power tool.

Brush edge
The grinding head of this power tool is enclosed by
a brush edge (1 0) which offers the following two
advantages:
a) The brush edge (1 0) protrudes beyond the grind-
ing plate (9) and touches the surface to be pro-
cessed first. Thus, the grinding plate is positioned
in parallel to the working area before the insertion
tool comes in contact with the surface which is
to be processed. This is to prevent the formation
of sickle-shaped recesses caused by the grind-
ing disk edge.
b) Furthermore, the brush edge (10) prevents the
generation of excessive dust. Dust generated du
ring the grinding process is not transported to-
wards the outside but is removed by the extrac-
tion system. Make sure before each operation
with this power tool that the brush edge (10) is
not damaged. Have it replaced if there is dam-
age or wear.
Connection to the power supply
1. Make sure that the power tool is switched off.
Always switch the on/off switch (3) to off position
before connecting the power tool to the power
supply.
2. Plug the power plug into a correctly installed
socket which complies with the requirements
specified in the technical data.
3. Your power tool is now ready for operation.

8. Operation

Oscillation rate
Before you start working with the swing speed to
match the appliance. Use a low swing speed for
coarse grinding, increase the oscillation rate for fine
work.
1. Rotate the adjustment wheel (6) to adjust the os-
cillation rate. Turn the wheel clockwise to reduce
the oscillation rate (fig. 9).
2. Turn the wheel counter-clockwise to increase the
oscillation rate (fig. 10).
Switching on/off
To switch on:
Push the on/ off switch (3)
Continuous operation: (fig. 11)
Secure the on/off switch (3) with the locking button
(a)
To switch off:
Press the on/off switch (3) briefly.
Note: The insertion tool moves for a short while after
having it switched off. Do not put aside the power tool
until the insertion tool has come to a complete halt.
