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.
The power tool must always work in an
up-grinding motion. Otherwise there
is a risk that it will be pushed uncon-
trolled out of the cut.
For best results when cutting profiles
and rectangular tubing, start at the
smallest cross section.
Cutting stone
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.
Operate the power tool only with dust extraction and also
wear a dust respirator.
The vacuum cleaner must be approved for the extraction of
stone dust. Suitable vacuum cleaners are available from
Bosch.
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 mo-
tion that is suited to the material being
machined.
When cutting especially hard materi-
als such as concrete with a high
pebble content, the diamond cutting disc can overheat and
become damaged as a result. This is clearly indicated by cir-
cular sparking, rotating with the diamond 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 has become dull. You
can resharpen the disc by briefly cutting into abrasive mater-
ial (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 (31).

Working with Diamond Annular Cutters
Only use dry diamond annular cutters.
u
Always fit the hand guard (23) 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.
Start-Up
Switching on/off
To start the power tool, push the on/off switch (3) forward.
To lock the on/off switch (3) in position, push the on/off
switch (3) forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (3);
or, if the switch is locked, briefly push the on/off switch (3)
backward and down and then release it.
Always check abrasive tools before using them. The
u
abrasive tool must be fitted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use abrasive tools that are
damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Maintenance and Service
Maintenance and Cleaning
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Store and handle the accessories carefully.
