Noise/Vibration Information

Measured values determined according to EN 60745.
Typically the A-weighted noise levels of the product are: Sound pressure level 99 dB(A); Sound power
level 110 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) determined
according to EN 60745:
Drilling into metal:
Vibration emission value a
Uncertainty K=
Impact drilling into concrete:
Vibration emission value a
Uncertainty K=
Screwdriving:
Vibration emission value a
Uncertainty K=
The vibration emission level given in this informa-
tion 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 ex-
posure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing 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 total
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.
