■
Hold electric tools by their insulated han-
dles whenever there is the possibility of
touching hidden wires or the tools‚ own
cords while using them.
Touching a “live” wire can transfer the voltage
to the exposed metal parts of the tool and give
the operator an electric shock.
■
Do not drill, saw or cut in blind areas where
there could be hidden electric, gas or water
lines. Use the appropriate detectors to find
these lines in the work area or call the local
utility company for assistance.
Touching electric lines may cause fire or elec-
tric shock. Striking a gas line will probably re-
sult in an explosion. Breaking into a water pipe
will cause property damage or may cause an
electric shock.
■
The protective hood
6
must be mounted when
working with roughing or cutting discs. When
working with the rubber sanding plate
19
or
with the cup brush
22
/disc brush/flap disc, we
recommend you to mount the hand protec-
tor
17
(optional extra).
■
When working with stone, use a vacuum
cleaner for removing dust. The vacuum
cleaner must be approved for removing ma-
sonry dust. When cutting stone, use the cutting
guide.
■
Don’t work with materials containing asbestos.
■
Useonly grinding tools whose allowablespeed
is at least as high as the idling 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 wheel 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. Because of a possible fire hazard, no
combustiblematerials should be nearby (spark
flying zone).
■
Be careful when cutting grooves, e. g. in load-
carrying walls: See the information on statics.
■
Blocking the cutting disc leads to a strong jerk-
ing reaction of the machine. If this happens,
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 re-
garding mounting and use of grinding tools.
■
Caution! The grinding wheel keeps running af-
ter the machine has been switched off.
■
Do not tighten the machine in a vise.
■
Never allow children to use the machine.
■Bosch can only guarantee a flawless function-
ing of the machine if the original accessories
intended for it are used.
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.
Slots in load-carrying walls are subject to Part 1
of the German Industrial Standard (DIN)
No. 1053, or to 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.
