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.
