2
.
Intended Use
The machine is intended for cutting, roughing and
brushing metal and stone materials without using
water. For cutting stone, a cutting guide is required.
For machines with electronic control: With approved sanding tools, the machine can be used
for sanding and polishing.
Information on Structures
Slots in structural walls are subject to the Standard DIN 1053, Part 1 or country-specific regulations.
These regulations are to be observed under all
circumstances. Before beginning work, consult
the responsible structural engineer, architects or
the construction supervisor.
For Your Safety
Working safely with this machine is possible only when the
operating and safety information
are read completely and the instructions contained therein are
strictly followed. In addition, the
general safety notes in the enclosed booklet
must be observed. Before using for the first
time, ask for a practical demonstration.
■ Wear protective glasses and hearing protec-
tion.
■ Wear additional protection equipment for your
safety, such as protective gloves, sturdy
shoes, hard hat and apron.
■ The dust that is produced while working can be
detrimental to health, inflammable or explosive. Suitable safety measures are required.
Examples: Some dusts are regarded as carcinogenic. Use suitable dust/chip extraction and
wear a dust respirator.
■ Dust from light alloys can burn or explode. Al-
ways keep the workplace clean, as blends of
materials are particularly dangerous.
■ If the mains cable is damaged or cut through
while working, do not touch the cable but immediately pull the mains plug. Never use the
machine with a damaged cable.

■ Connect machines that are used in the open
via a residual current device (RCD) with an actuating current of 30 mA maximum. Do not operate the machine in rain or moisture.
■ When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
■ Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
■ Always direct the cable to the rear away from
the machine.
■ Always switch the machine off and wait until it
has come to a standstill before placing it down.
■ For power outage or when the mains plug is
pulled, unlock the On/Off switch immediately
and turn it to the off position. This prevents uncontrolled restarting.
■ The machine must be used only for dry cutting /
grinding.
■ For all work with the machine, the auxiliary
handle must be mounted.
■ Hold the power tool only by the insulated
gripping surfaces, when performing an operation where the cutting tool may run into
hidden wiring or its own cord.
Contact with a “live” wire will make exposed
metal parts of the tool “live” and shock the operator.
■ Use appropriate detectors to determine if
utility lines are hidden in the work area or
call the local utility company for assistance.
Contact with electric lines can lead to fire and
electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes
property damage or may cause an electric
shock.
■ For work with grinding or cutting discs, the protection guard 6 must be mounted. For work
with the rubber sanding plate 13 or with the
cup brush 16/disc brush/flap disc, the hand
guard 12 (accessory) is to be mounted.
■ Use dust extraction when working with stone.
The vacuum cleaner must be approved for masonry dust. When cutting stone, use the cutting
guide.
■ Do not work with materials containing asbestos.
■ Use only grinding tools with a permissible
speed at least as high as the no-load speed of
the machine.
■ Check grinding tools before use. The grinding
tool must be properly mounted and turn freely.
Perform a test run for at least 30 seconds without load. Do not use damaged, out-of-round or
vibrating grinding tools.
■ Protect the grinding tool from impact, shock
and grease.
■ Apply the machine to the workpiece only when
switched on.
■ Keep hands away from rotating grinding tools.
■ Pay attention to the direction of rotation. Al-
ways hold the machine so that sparks and
grinding dust fly away from the body.
■ When grinding metal, flying sparks are produced. Take care that no persons are endangered. Due to danger of fire, no combustible
materials should be located in the vicinity
(spark flight zone).
■ Be careful when cutting grooves, e. g. in structural walls: See Information on Structures.
■ Blocking the cutting disc leads to jerking reaction forces on the machine. In this case switch
off the machine immediately.
■ Observe the dimensions of the grinding discs.
The hole diameter must fit mounting
flange 8 (M 14), 17 (M 10). Do not use any reducers or adapters.
■ Never use cutting discs for rough grinding. Do
not exert any lateral pressure on the cutting
discs.
■ Observe the manufacturer’s instructions for
mounting and using grinding tools.
■ Caution! The grinding tool runs on after the
machine is switched off.
■ Do not clamp the machine in a vice.
■ Never allow children to use the machine.
■ Bosch is only able to ensure perfect operation
of the machine if the original accessories intended for it are used.
