Bosch GWS 7-115 Operating Instructions Manual page 7

Always switch the machine off and wait until it
has come to a standstill before placing it down.
Insert the mains plug only when the machine is
switched off.
For mains failure or when the main 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 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.
Do not drill, cut or saw into blind areas
where electric, gas or water lines may exist.
Use suitable detectors to determine if these
lines are hidden in the work area or call the
local utility company for assistance.
Contact with electric lines may cause fire or
electric shock. Damaging a gas line can result
in an explosion. Penetrating a water pipe will
cause property damage or may cause an elec-
tric shock.
For work with roughing or cutting discs, the
protective guard 6 must be mounted. For work
with the rubber sanding plate 13 or with the
cup brush 16/disc brush/flap disc, mounting
the hand protector 12 (accessory) is recom-
mended.
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 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.
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.
