Noise/Vibration Information

Measured sound values determined according
to EN 60745.
Typically the A-weighted noise levels of the
product are: Sound pressure level 90 dB(A);
Sound power level 101 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: Vibrational emis-
2
sion value a =18 m/s , uncertainty K=1.5 m/s
h
Drilling in metal: Vibrational emission value
2
a <2.5 m/s , uncertainty K=1.5 m/s
h
Screwdriving without impact: Vibrational emis-
2
sion value a <2.5 m/s , uncertainty K=1.5 m/s
h
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 12.
Changing the position of the auxiliary handle
(see figure A)
The auxiliary handle 12 can be set to any posi-
tion for a secure and low-fatigue working pos-
ture.
– Turn the bottom part of the auxiliary handle
12 in counterclockwise direction and swivel
the auxiliary handle 12 to the desired posi-
tion. Then retighten the bottom part of the
auxiliary handle 12 by turning in clockwise di-
rection.
