Bosch GWS 21-180 H Operating Instructions Manual page 16

For all work with the machine, the auxiliary
handle 4 must be mounted.
Hold tools by insulated gripping surfaces
when performing an operation where the
cutting tool may contact 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.
Do not drill, fasten or cut into blind areas
where electric, gas or water lines may exist.
Use appropriate detectors to determine if
these lines are hidden in the work area or
call the local utility company for assis-
tance.
Contacting electric lines may cause fire or
electric shock. Striking a gas line will probably
result in explosion. Breaking into a water pipe
will cause property damage or may cause an
electric shock.
For work with roughing or cutting discs, the
protective guard 6 must be mounted. For work
with the rubber sanding plate 19 or with the
cup brush 22/disc brush/flap disc, mounting
the hand protector 17 (optional extra) is rec-
ommended.
Use a vacuum cleaner for drawing off the dust
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 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 load-
carrying 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-
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 function-
ing of the machine if the original accessories
intended 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.
Information Structures
Slots in load carrying 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.
