Noise/Vibration Information
Measured
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 =2 dB.
Wear hearing protection!
Vibration total values (triax vector sum) determined
according to EN 60745:
Hammer drilling into concrete: Vibration emission
value a
Chiselling: Vibration emission value a
Uncertainty K=1,5 m/s
measured in accordance with a standardised test
given in EN 60745 and may be used to compare one
tool with another.
The vibration emission level will vary because of the
ways in which a power tool can be used and may
increase above the level given in this information
sheet. This could lead to a significant underestimate
of exposure when the tool is used regularly in such a
way.
Note: To be accurate, an estimation of the level of
exposure to vibration experienced during a given
period of work should also take into account the times
when the tool is switched off and when it is running
