Metal Cutting
A Type 41/1A wheel guard
may not be included with
this tool but is required when using a cutting
wheel. Cutting with a Type 27 wheel guard
may not provide the operator sufficient protec-
tion in the event of a wheel burst.
With this grinder it is possible to perform cut-
ting of limited small stock such as metal tubes,
piping or rebar. When cutting, work with mod-
erate feed, adapted to the material being cut.
When cutting profiles and square bar, it is best
to start at the smallest cross section.
Always follow precautions for kickback.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. The tool should always be used in such
way that the sparks are directed away from
user.
3. 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.
4. Do not exert side pressure onto the cutting
disc. Do not tilt or oscillate the tool as
wheel may burst, (Fig. 22).
5. Remove the tool from the work surface
before turning the tool off. Allow the tool
to stop rotating before laying it down.

Operating Instructions
Masonry / Concrete Cutting
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 ap-
plication must be approved for the extraction
of masonry and concrete dust. Bosch sells suit-
able vacuum cleaners.
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. Masonry dust is abrasive and may wear
and weaken the segment bond.

Never pull the tool back-
ward since blade will climb
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
direction 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
maximize dust extraction and reduce likeli-
hood 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.
