Noise/Vibration Information

Measured values
EN 60745.
Typically the A-weighted noise level of the machine is:
sound pressure level 87 dB(A); sound power level
98 dB(A). Uncertainty K=3 dB.
Wear hearing protection!
Overall vibrational value (vector sum of three direc-
tions) determined according to EN 60745:

The vibration emission level given in
WARNING
this information sheet has been
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
but not actually doing the job. This may significantly
reduce the exposure level over the total working
period.
