The vibration and/or noise emission level given in this information sheet has
been measured in accordance with a standardised test given in EN62841
and may be used to compare one tool with another. It may be used for a
preliminary assessment ofexposure.

WARNING: The declared vibration and/or noise 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 and/or noise emission may differ. This may
significantly increase the exposure level over the total workingperiod.
An estimation of the level of exposure to vibration and/or noise should
also take into account the times when the tool is switched off or when
it is running but not actually doing the job. This may significantly
reduce the exposure level over the total workingperiod.
Identify additional safety measures to protect the operator from the
effects of vibration and/or noise such as: maintain the tool and the
accessories, keep the hands warm (relevant for vibration), organisation
of workpatterns.
