Protection class
The values given are valid for nominal voltages [U] of 230/240 V. For lower voltage and models for specific countries, these val-
ues can vary.
Please observe the article number on the type plate of your machine. The trade names of the individual machines may vary.
Noise/Vibration Information
Measured values determined according to EN 60745.
Typically the A-weighted noise level of the machine is:
sound pressure level 86 dB(A); sound power level
97 dB(A). Uncertainty K=3 dB.
Wear hearing protection!
Overall vibrational values (vector sum of three direc-
tions) determined according to EN 60745:

The vibration emission level given in
WARNING
this information sheet has been meas-
ured 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.
