Rubber Sanding Plate 11
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.
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.
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.
■ 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
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.
Never use a cutting disc for roughing.
Cutting
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.
The direction in
which the cutting is
performed is impor-
tant.
The machine must
always work in an
up-grinding motion.
Therefore, never
move the machine in
the other direction!
Otherwise, the dan-
ger exists of it being
pushed uncon-
trolled out of the cut.
When cutting profiles and square pipes, it is best
to start with the smallest cross section.
