Depending on the application, remove the protec-
tion guard 5 and mount the hand guard 10.
For mounting, see the illustration page.
Screw on the round nut 13 and tighten with the
two-pin spanner.
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.

Starting 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 1
forward.
To lock-on, press the On/Off switch 1 down at
the front until it engages.
To switch off the machine, release the On/Off
switch 1 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.

Operating Instructions
Clamp the workpiece if it does not remain
stationary due to its own weight.
Do not strain the machine so heavily that it
comes to a standstill.
Grinding and cutting discs become very
hot while working; do not touch until they
have cooled.

Rough Grinding

Never use a cutting disc for roughing.

When cutting profiles and square pipes, it is best
to start with the smallest cross section.

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.
Do not reduce the speed of running
down cutting discs by applying
sideward pressure.
