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.
The vibration and/or noise emission level given in this information
sheet has been measured in accordance with a standardised test
given in EN60745 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.
