■ Clamp the workpiece if it does not remain
stationary due to its own weight.
■ Do not load the machine so heavily that it
comes to a standstill.
■ Roughing and cutting discs become very
hot while working; do not touch until they
have cooled.
Rough Grinding
With an approach angle of 30° to
40°, the best roughing results can
be achieved. Move the machine
back and forth with moderate pres-
sure. In this manner, the work piece
will not become too hot, does not
discolour and no ridges are formed.
Never use a cutting disc for roughing.
Flap disc
With the flap disc (optional extra), curved sur-
faces 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
When cutting, do not press, tilt or
oscillate. Work with moderate ad-
vancing that is adapted to the mate-
rial being worked.
Do not brake coasting cutting disks with side
pressure.
Important is the direc-
tion in which cutting is
performed.
The machine must al-
ways work opposite
to the direction of ro-
tation. Therefore,
never move the ma-
chine in the other di-
rection! Otherwise,
the danger exists of it
being pushed uncon-
trolled out of the cut.
Cutting grinder Stand
With the cutting grinder stand 18 (optional extra),
work pieces of the same length can be cut at an-
gles of 0 to 45°.
When cutting profiles and square pipes, it is best
to start with the smallest cross section.
Cutting Stone
■ The machine must be used only for dry cut-
ting/grinding.
It is best to work with
a diamond cutting
disc. To ensure
against tilting, the
cutting guide 21
with special protec-
tive vacuuming hood
must be used.
The machine must be operated only with dust ex-
traction. In addition, wear a dust mask.
The vacuum cleaner
must be approved for
the extraction of ma-
sonry dust.
Bosch provides suita-
ble vacuum cleaners.
Switch on the ma-
chine and place the
front part of the cut-
ting guide on the
workpiece.
Slide the machine with moderate advancing that
is adapted to the material to be worked (Figure).
For cutting especially hard material, e. g., con-
crete with high gravel content, the diamond cut-
ting disc can overheat and become damaged as
a result. This is indicated clearly by a ring of
sparks that rotates with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
frely at no-load speed for a short time.
Noticeable decreasing work progress and a rotat-
ing spark ring are indications of a diamond cutting
disc that has become dull. With brief cuts in an
abrasive material (e. g., chalky sand stone), it can
be sharpened again.
