Bosch Professional GSB 18-2 Original Instructions Manual page 18

Take protective measures when dust can de-
velop during working that is harmful to one's
health, combustible or explosive. Example:
Some dusts are regarded as carcinogenic.
Wear a dust mask and work with dust/chip ex-
traction when connectable.
Keep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.
Always wait until the machine has come to a
complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
Never use the machine with a damaged ca-
ble. Do not touch the damaged cable and pull
the mains plug when the cable is damaged
while working. Damaged cables increase the
risk of an electric shock.
Functional Description
Read all safety warnings and all in-
structions. Failure to follow the
warnings and instructions may result
in electric shock, fire and/or serious
injury.
While reading the operating instructions, unfold
the graphics page for the machine and leave it
open.
Intended Use
The machine is intended for impact drilling in
brick, concrete and stone as well as for drilling in
wood, metal and plastic. Machines with electron-
ic control and right/left rotation are also suitable
for screwdriving and thread-cutting.

Noise/Vibration Information
Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the prod-
uct are: Sound pressure level 97 dB(A); Sound
power level 108 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Drilling into metal: Vibration emission value
2
a =5.0 m/s , Uncertainty K =1.5 m/s
h
Impact drilling into concrete: Vibration emission
2
value a =17 m/s , Uncertainty K =2.0 m/s
h
Screwdriving: Vibration emission value
2
a <2.5 m/s , Uncertainty K =1.5 m/s
h
The vibration emission level given in this informa-
tion sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another. It
may be used for a preliminary assessment of ex-
posure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing period.
