Noise/Vibration Information
Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 93 dB(A);
Sound power level 104 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-
sion value a =10 m/s
h
Chiselling: Vibration emission value a
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.

Before any work on the machine itself, pull
the mains plug.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 9.
The auxiliary handle 9 can be set to any position
for a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 9 in
counterclockwise direction and swivel the auxil-
iary handle 9 to the desired position. Then
retighten the bottom part of the auxiliary handle
9 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.
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.
The red symbols (open lock and bars) on the lock-
ing sleeve 2 indicate that the tool holder is open.
Insert the tool into the tool holder with a turning
motion until it is automatically locked. The lock-
ing sleeve automatically snaps toward the front
and the red ring is no longer visible. This indi-
cates that the tool holder is locked.
