Intended Use - Bosch GWS 21-180 H Professional Bedienungsanleitung

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 plate 20 or with the
cup brush 23/disc brush/flap disc, the hand
guard 18 (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.
Pay attention to the dimensions of the grinding
disc. The mounting hole diameter must fit the
mounting flange 9 without play. Do not use 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.

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 re-
quired.
