Noise/Vibration Information
Measured values determined according to EN 60745.
Typically the A-weighted noise level of the machine is:
sound pressure level 85 dB(A); sound power level
96 dB(A). Uncertainty K=3 dB.
Wear hearing protection!
The typical hand/arm vibration is below 2.5 m/s
The vibration emission level given in this
WARNING
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 expo-
sure 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.
Declaration of Conformity
We declare under our sole responsibility that this prod-
uct is in conformity with the following standards or
standardization documents: EN 60745 according to
the provisions of the
98/37/EC.

Operation
Starting Operation
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
