The vibration emission level given in this information sheet has been 
measured in accordance with a standardised test given in EN 61029 
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.
   An estimation of the level of exposure to vibration 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 such as: maintain the tool and 
the accessories, keep the hands warm, organisation of 
work patterns.
