Owners of the Bosch cut-
ting stand of the design in
figure A require the cap a
(optional extra set, order
no. 2 607 001 306).
Owners of the Bosch cut-
ting stand of the design in
figure B require the claw b
(optional extra set, order
no. 2 607 001 306).
The handle must be
locked in the position
shown in figure C (with the
On/Off switch pointing
downwards). In any other
position the handle and
the handle unlocking lever
can become damaged by
the grinding dust deposit.
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 23
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 suit-
able vacuum clean-
ers.
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.
■ Before any work on the machine itself, pull
the mains plug.
The machine head
can be rotated with
respect to the ma-
chine housing in 90°
steps. In this man-
ner, the on/off switch
can be brought to an
advantageous han-
dling position for
special working situ-
ations, e. g., for cut-
ting work with the
cutting guide 23/
cut-off stand (op-
tional extra) or for
left-handed persons.
Unscrew completely the four screws.
Rotate the machine head carefully and without
removing from the housing to the new position.
Screw in the screws again and tighten.
