■ The machine must be used only for dry cutting/
grinding.
■ For all work with the machine, the auxiliary
handle 3 must be mounted.
■ Hold the power tool only by the insulated
gripping surfaces, when performing an op-
eration 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 op-
erator.
■ Use appropriate detectors to determine if
utility lines are hidden in the work area or
call the local utility company for assist-
ance.
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 pro-
tection guard 6 must be mounted. For work
with the rubber sanding pad 13 or with the cup
brush 16/disc brush/flap disc, mounting the
hand guard 12 (accessory) is recommended.
■ Use dust extraction when working with stone.
The vacuum cleaner must be approved for ma-
sonry dust. When cutting stone, use the cutting
guide.
■ Do not work with materials containing asbes-
tos.
■ 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 with-
out 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 pro-
duced. Take care that no persons are endan-
gered. 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 struc-
tural walls: See Information on Structures.
■ Blocking the cutting disc leads to jerking reac-
tion forces on the machine. In this case switch
off the machine immediately.
■ Pay attention to the dimensions of the grinding
disc. The mounting hole diameter must fit the
mounting flange 8 without play. Do not use re-
ducer pieces 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 in-
tended for it are used.
■ Before any work on the machine itself, pull
the mains plug.
Protection Guard
■ For work with grinding or cutting discs, the
protection guard 6 must be mounted.
Open the clamping lever 7.
Place the protection guard 6 onto the spindle col-
lar of the machine head as shown in the illustra-
tion. The encoding keys of the protection guard
must match with the respective recesses on the
spindle collar.
