8. Operation
m ATTENTION!
Always make sure the product is fully assembled
before commissioning!
Oscillation rate
Before starting work, set the oscillation rate to suit the
application. Use a low oscillation rate for coarse grind-
ing work, increase the oscillation rate for fine work.
1. Adjust the oscillation rate by turning the setting
wheel (6). Turn to the right to reduce the oscilla-
tion rate (Fig. 9).
2. Turn to the left to increase the oscillation rate
(Fig. 10).
Switching on/off
Switching on:
Press the ON/OFF switch (3)
Continuous operation: (Fig. 11)
Secure the ON/OFF switch (3) with the locking knob (a).
Switching off:
Press in the ON/OFF switch (3) briefly.
Note: The tool attachment continues to rotate a little
after it has been switched off. Wait until the tool at-
tachment has come to a standstill before putting the
electric tool down.
Sanding
1. Attach a suitable sanding sheet (13) and select a
suitable speed.
2. Hold the electric tool securely by the gripping sur-
faces (1, 2) and switch it on as described.
3. Wait until the tool attachment has reached its full
working speed.
4. Guide the grinding plate (9) as parallel as possible
to the wall and place it with the brush edge (10)
first on the surface to be worked on.
5. Apply some pressure on the grinding head (8) to
bring the tool attachment into contact with the sur-
face to be worked.
6. Move the electric tool over the surface with even
movements.
Note: Do not hold the electric tool in one place for too
long to avoid uneven sanding results.
7. Lift the grinding plate (9) from the surface to be
worked on before switching off the electric tool.

standstill before putting the electric tool down.
Sanding a ceiling (Fig. 12)
1. When working on a ceiling area, fix the grinding
head in place using the split pin (15) (included
in the scope of delivery) as shown in Figure 12.
After use
1. Switch off the electric tool as described, disconnect
it from the power supply and allow it to cool down.
2. Clean and maintain the electric tool as described
below and then store it carefully.
9. Cleaning, maintenance and repair
m Warning!
Remove the mains plug from the socket before
working on the electric tool itself (e.g. transport, set
up, modification, cleaning and maintenance work)!
Cleaning
a) Keep protective devices, ventilation openings
and the motor housing as free of dust and dirt
as possible.
b) Wipe the electric tool clean with a clean cloth or
blow it off with compressed air at low pressure
(max. 3 bar).
c) Clean the electric tool immediately after each use.
d) Do not use any cleaning products or solvents as
they could attack the plastic parts of the device.
Make sure that no water can penetrate the de-
vice interior.
Replacing the mains connection cable
If the mains connection cable for the electric tool is
damaged then it must be replaced by the manufacturer
or their customer services personnel or by a similarly
qualified person, in order to avoid hazards.
Maintenance
Before and after each use, check the electric tool and
accessories (e.g. tool attachments) for wear and dam-
age. If necessary, replace them with new ones as de-
scribed in this operating manual. When doing so, ob-
serve the technical requirements.
Grinding plate, brush edge
If the grinding plate (9) and the brush edge (10) are
damaged or badly worn, have them replaced by a qual-
ified specialist with new ones of the same type.
