Lock the grinder spindle with the spindle locking
button 5. Tighten the quick clamping nut by force-
fully turning the grinding disc in the clockwise di-
rection.
A properly tightened undamaged, quick clamping
nut can be loosened by hand turning the knurled
ring in the counter-clockwise direction.
Never loosen a tight quick clamping nut with
pliers but use a two-hole spanner. Insert the
two-hole spanner as shown in the illustration.

Instead of the clamp-
ing nut 11, the quick
clamping nut 12 (op-
tional extra) can be
used. Grinding tools
can be mounted with-
out using tools.
The quick clamping
nut 12 may be used
only for roughing
and cutting discs.
Use only a flawless,
undamaged quick
clamping nut 12.
When screwing on,
take care that the side
with printing does not
point to the grinding
disc. The arrow must
point to the index
mark 22.
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.
Switching off: Release the On/Off switch 3.
Locking: Slide the on/off switch 3 forward
and press down to the front until
it latches.
Switching off: Press down the on/off switch 3 to
the rear - the switch springs to
the off position.
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 (Type C/CE)
As a result of soft starting, a 16-A fuse is ade-
quate.
Constant Electronics (Type C/CE)
The constant speed electronics hold the speed at
no-load and when under load nearly constant and
ensure uniform working performance.

Overload Protection

When overloaded, the motor comes to a stop. Re-
lieve the load on the machine immediately and al-
low to cool for approx. 30 seconds at the highest
no-load speed.
Speed Selection (Type CE)
Preselect the required speed using the thumb
wheel 2 according to the table following the sec-
tion "Product Specification" (reference values).
