Noise/Vibration Information

Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 86 dB(A);
Sound power level 97 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 =14 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.

Assembly
Before any work on the machine itself, pull
the mains plug.

Auxiliary Handle

Operate your machine only with the auxilia-
ry handle 11.
Rotating the Auxiliary Handle (see figure A)
The auxiliary handle 11 can be set to any posi-
tion for a secure and low-fatigue working pos-
ture.

– Turn the wing bolt for adjustment of the aux-
iliary handle 18 in anticlockwise direction
and set the auxiliary handle 11 to the re-
quired position. Then tighten the wing bolt
18 again in clockwise direction.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the
depth stop 9.
– Loosen the wing bolt for depth stop adjust-
ment 19.
– Pull out the depth stop until the distance be-
tween the tip of the drill bit and the tip of the
depth stop correspond with the desired drill-
ing depth X.
– Retighten the wing bolt for the depth stop
adjustment 19 again.
Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus
tools are required that are inserted in the SDS-
plus drill chuck.
For drilling without impact in wood, metal, ce-
ramic and plastic as well as for screwdriving,
use the quick change keyless chuck and drilling
tools without SDS-plus.
