Approved Grinding Tools
All grinding tools mentioned in this operating
manual instruction can be used.
The permissible speed [rpm] or the circumferen-
tial speed [m/s] of the grinding tools used must at
least match the values given in the table.
Therefore, always observe the permissible
rotational/circumferential speed on the label
of the grinding tool.

Initial Operation
Observe 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.
To start the machine, press the On/Off switch 2
forward.
To lock-on, press the On/Off switch 2 down at
the front until it engages.
To switch off the machine, release the On/Off
switch 2 or press the rear tip of it down.
Test run!
Check the grinding tool before use. The
grinding tool must be properly mounted
and rotate freely. Perform a test run of at
least 30 seconds without load. Do not use
damaged, out-of-round or vibrating grind-
ing tools.
Reduced Starting Current
As a result of soft starting, a 13 A fuse is ade-
quate.
A machine without reduced starting current re-
quires higher fuse protection (use at least a
13 A time-delay fuse).

Constant Electronic Control
Constant electronic control holds the speed con-
stant at no-load and under load, and ensures uni-
form working performance.
Speed Preselection
Preselect the required speed using the thumb-
wheel 1 according to the table following the sec-
tion "Product Specification" (reference values).
Operating Instructions
Clamp the workpiece if it does not remain
[m/s]
stationary due to its own weight.
Do not strain the machine so heavily that it
80
comes to a standstill.
Grinding and cutting discs become very
hot while working; do not touch until they
80
have cooled.
Rough Grinding
45
Never use a cutting disc for roughing.
Flap Disc
With the flap disc (accessory), curved surfaces
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
Do not reduce the speed of running down cutting
discs by applying sideward pressure.
English - 6
The best roughing results are
achieved when setting the machine
at an angle of 30° to 40°. Move the
machine back and forth with mod-
erate pressure. In this manner, the
workpiece will not become too hot,
does not discolour and no grooves
are formed.
When cutting, do not press, jam or
oscillate the machine. Work with
moderate feed, adapted to the ma-
terial being machined.
