Lock the grinder
spindle with the spin-
dle locking button 2.
Tighten the quick
clamping nut by
forcefully turning the
grinding disc clock-
wise.
A properly tightened
and undamaged
quick clamping nut
can be loosened by
turning the knurled
ring counter-clock-
wise.
Never loosen a
tightened quick
clamping nut with
pliers. Instead, use
a two-hole spanner.
Insert the two-hole
spanner as shown in
the illustration.
Always use the correct voltage: The voltage of
the power source must agree with the values on
the nameplate of the machine.
Switching On and Off
To start the unit, push the On/Off switch 3 for-
wards but without pressing it, then press it down.
To lock on, push the pressed On/Off switch 3
further forwards.
To switch the unit off, release the On/Off
switch 3 or push and release it then.
Switch configuration without lock
(specific countries):
To start the unit, push the On/Off switch 3 for-
wards but without pressing it, then press it down.
To switch off the unit, 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 or vibrating grinding
tools.
Starting Current Limiting
(Type J)
As a result of controlled starting of the
machine, a 16 A fuse is adequate.
A machine that lacks a residual current
delimitation needs a higher degree of
fuse protection (put in at least a 16 A de-
layed action fuse).
■ Clamp down the workpiece if it does not
stay in place owing to its own weight.
■ Do not load the machine so heavily that it
comes to a standstill.
■ Since roughing and cutting discs become
very hot while working, do not touch them
until they have cooled.
Rough Grinding
The best roughing results can be
achieved with a 30° to 40° ap-
proach angle. Move the machine
back and forth with moderate pres-
sure. In this manner, the work piece
will not overly heat up nor discolor
and no ridges will be formed.
Never use a cutting disc for roughing.
Flap disc
The flap disc (optional extra) can be used for
working on curved surfaces and profiles (contour
sanding).
Flap discs have a considerably higher service life
than sanding sheets, a lower noise level and
lower sanding temperatures.
Cutting
When cutting, do not press, tilt or
oscillate. Gently slide it forward with
a speed adapted to the material be-
ing worked on.
Do not brake cutting discs that are
slowing down to a stop by using
side pressure.
