Bosch GWS 26-180 B Operating Instructions Manual page 11

Cutting Grinder Stand
With the cutting grinder stand 27 (optional extra),
work pieces of equal length can be cut at 0 to 45°
angles.
The safety notes and operating instructions in the
corresponding operating instructions manual of
the angle grinder are to be strictly observed. Use
only original Bosch grinder stands.
Cutting Stone
The machine should only be used only for
dry cutting/grinding.
Operate the machine only with the dust extraction
device. In addition, wear a dust protection mask.

The cutting direction
is very important.
The machine must
always work opposite
to the direction of ro-
tation. Therefore,
never move the ma-
chine in the other di-
rection! Otherwise,
there is the danger of
it being pushed un-
controlled out of the
cut.

It is best to use a dia-
mond cutting-off
wheel. To prevent
the tool from tilting,
use the guide
block 24 with special
extraction protective
hood.

Gently slide the machine forward with a speed
adapted to the material to be worked on (Figure).
For cutting especially hard materials, 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 letting it
run freely at a no-load speed for a short time.
A noticeable drop in work performance and a ro-
tating spark ring indicate that the diamond cutting
disc has become dull. It can be resharpened with
brief cuts in an abrasive material (e. g., chalky
sand stone).
Rotating the Machine Head
Before any work on the machine itself, pull
the power plug.
Unscrew the four screws completely.
Rotate the machine head carefully and without
removing it from the housing bring it to its new
position.
Screw in the screws again and tighten.
The vacuum cleaner
must be approved for
the vacuuming of
masonry 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.
The machine head
can be rotated in 90°
steps with respect to
the machine hous-
ing. By doing this,
the On/Off switch
can be brought to a
better position for
special working situ-
ations, e. g., for cut-
ting work with the
cutting guide 24/cut-
ting grinder stand 27
(optional extra) or for
left-handed persons.
