Noise/Vibration Information
Measured
values
determined
EN 60745.
Typically the A-weighted noise levels of the prod-
uct are: Sound pressure level 91 dB(A); Sound
power level 102 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Hammer drilling into concrete: Vibration emis-
2
sion value a
=21 m/s
, Uncertainty K=1.5 m/s
h
Chiselling: Vibration emission value a

Uncertainty K=1.5 m/s
.
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.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the
operator from the effects of vibration such as:
maintain the tool and the accessories, keep the
hands warm, organisation of work patterns.

Assembly
f Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
f Operate your machine only with the auxiliary
handle 8.
The auxiliary handle 8 can be set to any position
for a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 8 in
counterclockwise direction and swivel the auxil-
iary handle 8 to the desired position. Then
retighten the bottom part of the auxiliary handle
8 by turning in clockwise direction.
Changing the Tool
With the SDS-max tool holder, simpler and easier
tool changing is possible without additional aids.
The dust protection cap 1 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care that
the dust protection cap 1 is not damaged.
