8.5. Function of the brushed edge (fig.7)
The grinding head of this power tool is enclosed by a brush
edge (A) which offers the following two advantages:
a) The brush edge (A) protrudes beyond the grinding
plate (1) 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 pre-
vent the formation of sickle-shaped recesses caused by
the grinding disk edge.
b) Furthermore, the brush edge (A) prevents the genera-
tion of excessive dust. Dust generated du ring the grind-
ing 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
(A) is not damaged. Have it replaced if there is damage
or wear.

8.6. Connection to the power supply

1. Make sure that the power tool is switched off.
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.
8.7. Switching on/off (fig.8)
To switch on:
Push the on/ off switch (13)
Continuous operation: (fig.8)
Secure the on/off switch (13) with the locking knob (6).
To switch off:
Press the on/off switch (13) briefly and let go.
8.8. Adjusting the oscillation rate (fig.9)
Before you start working, adjust the oscillation rate accord-
ing to the application. Use a low number of oscillations for
rough grinding, increase the oscillation rate for fine work.
Adjust the oscillation rate by pressing the button (5).
• Press the button to increase the oscillation rate (fig.9).
• Press the button to decrease the oscillation rate (fig.9).
Note: The insertion tool moves for a short while after having
it switched off. Do not put aside the power tool until the inser-
tion tool has come to a complete halt.
8.9. Grinding
1. Attach an appropriate abrasive sheet (16) and select
the corresponding speed.
2. Hold the power tool securely at the handle surfaces (7,
2) and switch it on as described.
3. Wait until the insertion tool has reached its full operat-
ing speed.
4. Hold the grinding plate (1) as parallelas possible to the
wall, and touch the surface tobe processed with the
brush edge (A) first.
5. Apply some pressure to the grinding head (1) such that
the insertion tool touches the surface to be processed.

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 (1) 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.

8.10. 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 under
point 10, and store it carefully.
LED - light (fig.10)
To ensure a well lit workplace, use the LED-light (4) if neces-
sary.
Press the switch (a) to switch ON/OFF the LED-light (4).
Ceiling grinding (fig.11)
For working in ceiling area, fix the grinding head with a cot-
ter pin (C) (included) as shown in figure 11.

9. Electrical connection

The electrical motor installed is connected and ready
for operation. The connection complies with the appli-
cable VDE and DIN provisions. The customer's mains
connection as well as the extension cable used must
also comply with these regulations.
Damaged electrical connection cable
The insulation on electrical connection cables is often dam-
aged.
This may have the following causes:
• Passage points, where connection cables are passed
through windows or doors.
• Kinks where the connection cable has been improperly
fastened or routed.
• Places where the connection cables have been cut due to
being driven over.
• Insulation damage due to being ripped out of the wall
outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not be
used and are life-threatening due to the insulation damage.
Check the electrical connection cables for damage regu-
larly. Make sure that the connection cable does not hang on
the power network during the inspection.
Electrical connection cables must comply with the applicable
VDE and DIN provisions. Only use connection cables with
the marking „H05VV-F".
The printing of the type designation on the connection cable
is mandatory.
AC motor
• The mains voltage must be 220 - 240 V~ 50 Hz.
• Extension cables up to 25 m long must have a cross-sec-
tion of 1.5 mm .
