Noise/Vibration Information
Measured sound values determined according
to EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 95 dB(A);
Sound power level 106 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
2
Uncertainty K=1.5 m/s .
The vibration emission level given in this infor-
mation 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
exposure.
The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working 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 to-
tal 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
Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 6.
The auxiliary handle 6 can be set to any position
for a secure and low-fatigue working posture.
– Turn the bottom part of the auxiliary handle
6 in counterclockwise direction and swivel
the auxiliary handle 6 to the desired position.
Then retighten the bottom part of the auxilia-
ry handle 6 by turning in clockwise direction.
Changing the Tool
With the SDS-max tool holder, simpler and eas-
ier 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.
A damaged dust protection cap should be
changed immediately. We recommend hav-
ing this carried out by an after-sales serv-
ice.
