Dust extraction
m WARNING!
Harmfull noxious gases may be generated when
e.g. lead-containing paint is processed. These
gases entail a risk for the operator and the per-
sons 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 possible
to combine the extraction system or a vacuum cleaner
with the extraction hose (11) which is connected 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 ad-
vantages:
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 grinding
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 extraction
system. Make sure before each operation with this
power tool that the brush edge (10) is not dam-
aged. 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
before connecting the power tool to the power
supply.
2. Plug the power plug into a correctly installed sock-
et 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 grind-
ing, 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.
Grinding
1. Attach an appropriate abrasive sheet (13) and se-
lect the corresponding speed.
2. Hold the power tool securely at the handle surfac-
es (1, 2) and switch it on as described.
3. Wait until the insertion tool has reached its full
operating speed.
4. Hold the grinding plate (9) as parallel as possible
to the wall, and touch the surface to be 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
processed.
