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 un-
controlled restarting.
The machine must be used only for dry cutting/
grinding.
For all work with the machine, the auxiliary
handle must be mounted.
When performing an operation where the
tool insert can run into concealed electric
lines, hold the machine by the insulated
handles only.
Contact with a "live" wire will make exposed
metal parts of the tool "live" and shock the op-
erator.
Use suitable detectors to determine if util-
ity 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 pro-
tection 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 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.
Observe the dimensions of the grinding discs.
The hole
flange 8 (M 14), 19 (M 10). Do not use any re-
ducers 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.
