The vibration emission level given in 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. It may be
used for a preliminary assessment ofexposure.
WARNING: The declared vibration
emission level represents the main
applications of the tool. However if the
tool is used for different applications,
with different accessories or poorly
maintained, the vibration emission may
differ. This may significantly increase
the exposure level over the total
workingperiod.
