Masonry / Concrete Cutting
When cutting never pull the
tool backward since blade
will climb out of the material and KICKBACK
will occur.
With this grinder it is possible to perform cut-
ting of concrete and masonry materials . When
cutting, work with moderate feed, adapted to
the material being cut .
Always follow precautions for kickback .
Operate the tool with a dust extraction system
and personal dust protection, e .g . respirator,
dust mask, etc . The vacuum used for this appli-
cation must be approved for the extraction of
masonry and concrete dust . Bosch sells suitable
vacuum cleaners .
1 . Allow the tool to reach full speed before
touching the tool to the work surface .
2 . If plunge cutting:
a . Tilt tool forward with wheel lined up
with the cut line and hold the tool by the
grinder body and the auxiliary handle
(Fig . 23) .
b . Gradually lower the rear of tool using the
front end of the foot as the hinge point .
c . When the foot rests flat on the surface
being cut, proceed cutting in forward di-
rection to end of cut .
3 . Always maintain contact between the guard
foot and work piece .
4 . Slide the tool forward at a moderate speed
adapted to the material being cut . Always
cut towards the dust extraction port to maxi-
mize dust extraction and reduce likelihood
of kickback (Fig . 24) .
5 . Apply minimum pressure to the work sur-
face, allowing the tool to operate at high
speed . Cutting rate is greatest when the tool
operates at high speed .
6 . When the cut is completed, remove tool from
work piece before turning off . Allow wheel to
stop rotating before setting tool down .
Tip: When performing deep cuts, it is best to
cut in several shallow passes . Each pass should
be only to the segment depth of the wheel . Ma-
sonry dust is abrasive and may wear and weaken
the segment bond .

Operation
When cutting especially hard material, e . g .,
concrete with large aggregate content, the dry
diamond wheel can overheat and become dam-
aged . This is clearly indicated by circular spark-
ing of the rotating dry diamond wheel . In this
case, interrupt the cutting process and allow the
dry diamond wheel to cool by running the tool
for a short period of time at the maximum speed
with no-load .
Noticeable decreasing work progress and cir-
cular sparking are indications of a dry diamond
wheel that has become dull . Briefly cutting into
abrasive materials (e . g . brick) can resharpen
the wheel .
