The flap disc (accessory) enables you to machine curved
surfaces and profiles. Flap discs have a considerably longer
service life, lower noise levels and lower grinding temperat-
ures than conventional grinding discs.
Surface grinding with sanding disc
Always fit the hand guard (18) when working with the
u
rubber sanding pad (19).
Grinding with a sanding disc can be done without a protect-
ive guard.
See the graphics page for fitting instructions.
Cup brush/disc brush/conical brush
Always use the protective guard for grinding (10)
u
when brushing with disc brushes. Brushing with cup
brushes/conical brushes can be performed without
the protective guard.
Always fit the hand guard (18) when working with the
u
cup brush or conical brush.
The wires of the disc brush can get caught on the pro-
u
tective guard and break, if the maximum permitted di-
mensions of the disc brushes are exceeded.
See the graphics page for fitting instructions.
Cutting metal
Always use the protective guard for cutting (11) when
u
cutting with bonded abrasives.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.
Cutting Stone (see figure B)
Provide sufficient dust extraction when cutting stone.
u
Wear a dust mask.
u
The power tool may be used only for dry cutting/grind-
u
ing.
For best results when cutting stone, use a diamond cutting
disc.
When using the extraction guard for cutting with a cutting
guide (25), the vacuum cleaner must be approved for vacu-
uming stone dust. Suitable vacuum cleaners are available
from Bosch.
Bosch Power Tools
The power tool must always
work in an up-grinding mo-
tion. Otherwise there is a
risk that it will be pushed
uncontrolled out of the cut.
For best results when cut-
ting profiles and rectangular
tubing, start at the smallest
cross section.
crete with a high pebble content, the diamond cutting disc
can overheat and become damaged as a result. This is
clearly indicated by circular sparking, rotating with the dia-
mond cutting disc.
If this happens, stop cutting and allow the diamond cutting
disc to cool down by running the power tool for a short time
at maximum speed with no load.
If work is noticeably slower and with circular sparking, this
indicates that the diamond cutting disc that has become
dull. You can resharpen the disc by briefly cutting into abras-
ive material (e.g. lime-sand brick).
Cutting other materials
For cutting materials such as plastic, composite ma-
u
terials, etc. with bonded cutting discs or Carbide Multi
Wheel cutting discs, always use the protective guard
for cutting (11). You can achieve improved dust ex-
traction by using the extraction guard with a cutting
guide (25).
Working with Diamond Annular Cutters
Only use dry diamond annular cutters.
u
Always fit the hand guard (18) when working with dia-
u
mond annular cutters.
Do not place the diamond annular cutter parallel to the work-
piece. Plunge it into the workpiece at an angle and in a circu-
lar motion. This will allow you to achieve optimal cooling and
ensure a longer tool life for the diamond annular cutter.
Information on structural design
Recesses in load-bearing walls are subject to country-spe-
cific regulations. These regulations must be observed under
all circumstances. Seek advice from the responsible struc-
tural engineer, architect or construction supervisor before
starting work.

Switch on the power tool
and position it with the
front part of the cutting
guide on the workpiece.
Move the power tool with a
moderate feed motion that
is suited to the material be-
ing machined.
