Technical Data
Noise/Vibration Information
Measured values determined according to EN 60745.
Typically the A-weighted noise levels of the product
are: Sound pressure level 91 dB(A); Sound power
level 102 dB(A). Uncertainty K =3 dB.

Vibration total values (triax vector sum) determined
according to EN 60745:
Hammer drilling into concrete: Vibration emission value

=21 m/s

Chiselling: Vibration emission value a

.
The vibration emission level given in this information
sheet has been measured in accordance with a stand-
ardised test given in EN 60745 and may be used to
compare one tool with another. It may be used for a pre-
liminary assessment of exposure.
The declared vibration emission level represents the
main applications of the tool. However if the tool is
used for different applications, with different accesso-
ries or poorly maintained, the vibration emission may
differ. This may significantly increase the exposure level
over the total working period.
An estimation of the level of exposure to vibration
should also take into account the times when the tool
is switched off or when it is running but not actually
doing the job. This may significantly reduce the expo-
sure level over the total working period.
Identify additional safety measures to protect the oper-
ator from the effects of vibration such as: maintain the
tool and the accessories, keep the hands warm, organ-
isation of work patterns.
Declaration of Conformity
We declare under our sole responsibility that the product
described under “Technical Data” is in conformity with the
following standards or standardization documents: EN
60745 according to the provisions of the directives

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 counter-
clockwise direction and swivel the auxiliary 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.
f
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
Inserting (see figure A)
Clean and lightly grease the shank end of the tool.
Insert the tool in a twisting manner into the tool holder
until it latches itself.
Check the latching by pulling the tool.
Removing (see figure B)
Push back the locking sleeve
2
and remove the tool.
