Initial Operation
Check for correct mains voltage: The voltage
of the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching on: Slide the On/Off switch 3
forward without exerting any
pressure.
Press the On/Off switch 3.
Switching off: Release the On/Off switch 3.
Locking: Continue to slide the
On/Off switch 3 forward whilst
depressed.
Switching off: Press and release On/Off
switch 3.
Switch configuration without lock
(specific countries):
Switching on: Slide the On/Off switch 3
forward without exerting any
pressure.
Press the On/Off switch 3.
Switching off: Release the On/Off switch 3.
Test run!
Check the grinding tool before use. The
grinding tool must be flawlessly mounted
and be able to rotate freely. Perform a test
run of at least 30 seconds without load. Do
not use damaged, out-of-round or vibrating
grinding tools.
Starting Current Limiting
16 A
(Type J)
As a result of soft starting, a 13-A fuse is
adequate.
A machine without starting current-limiter
requires a higher fuse protection.
Operating Instructions
Clamp the workpiece if it does not remain
stationary due to its own weight.
Do not load the machine so heavily that it
comes to a standstill.
Roughing and cutting discs become very
hot while working; do not touch until they
have cooled.

Rough Grinding
Never use a cutting disc for roughing.
Flap disc
With the flap disc (optional extra), curved sur-
faces and profiles (contour sanding) can be
worked.
Flap discs have a considerably higher service life
than sanding sheets, lower noise level and lower
sanding temperatures.
Cutting
Cutting grinder Stand
With the cutting grinder stand (optional extra),
work pieces of the same length can be cut at an-
gles of 0 to 45°.
When cutting profiles and square pipes, it is best
to start with the smallest cross section.
For mounting the machine in the cutting stand a
cap or a claw are required, depending on the type
of cutting stand used.

With an approach angle of 30° to
40°, the best roughing results can
be achieved. Move the machine
back and forth with moderate pres-
sure. In this manner, the work piece
will not become too hot, does not
discolour and no ridges are formed.
When cutting, do not press, tilt or
oscillate. Work with moderate ad-
vancing that is adapted to the mate-
rial being worked.
Do not brake coasting cutting disks
with side pressure.
Important is the di-
rection in which cut-
ting is performed.
The machine must
always work opposite
to the direction of ro-
tation.
never move the ma-
chine in the other di-
rection!
the danger exists of it
being
controlled out of the
cut.
