by turning in a clockwise rotation (Fig.7).
2. Connect the dust extraction adapter with a suita-
ble dust extraction unit such as a vacuum cleaner
(Fig.8).
Note: Make sure that the vacuum cleaner is suitable
for being used tagether 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 advan-
tages:
a) The brush edge (1 0) protrudes beyond the grinding
plate (9) and touches the surface to be processed
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 re-
cesses caused by the grinding disk edge.
b) Furthermore, the brush edge (10) prevents the ge-
neration of excessive dust. Dust generated du ring
the grinding process is not transported towards the
outside but is removed by the extraction system.
Make sure before each operation with this power
tool that the brush edge (10) is not damaged. Have
it replaced if there is damage or wear.
Connection to the power supply
1. Make sure that the power tool is switched off. Al-
ways switch the on/off switch (3) to off position befo-
re connecting the power tool to the power supply.
2. Plug the power plug into a correctly installed socket
which camplies with the requirements specified in
the technical data.
3. Your power tool is now ready for operation.
Operation
Oscillation rate
Before you start working with the swing speed to
match the appliance. Use a low swing speed for coar-
se grinding, increase the oscillation rate for fine work.
1. Rotate the adjustment wheel (6) to adjust the oscil-
lation rate. Turn the wheel clockwise to reduce the
oscillation rate (Fig.9).
2. Turn the wheel counter-clockwise to increase the os-
cillation 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 Ieeking 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.
Grinding
1. Attach an appropriate abrasive sheet (13) and select
the corresponding speed.
2. Hold the power tool securely at the handle surfaces
(1, 2) and switch it on as described.
3. Wait until the insertion tool has reached its full ope-
rating speed.
4. Hold the grinding plate (9) as parallelas possible to
the wall, and touch the surface tobe processed with
the brush edge (10) first.
5. Apply some pressure to the grinding head (8) such
that the insertion tool touches the surface to be pro-

cessed.
6. Constantly move the power tool over the surface.
Note: lf you want to avoid irregular grinding results, do
not keep the power tool at one spot for too long.
7. Lift the grinding plate (9) from the surface to be pro-
cessed before switching off the power tool.
8. Do not put aside the power tool until the insertion
tool has come to a complete halt.
After use
1. Switch off the power tool as described, disconnect it
from the power supply and Iet it cool down.
2. Clean and maintain the power tool as described
below, and store it carefully.
