Hand/arm vibrations.
While working with this power
WARNING
tool, hand/arm vibrations
occur. These can lead to health impairments.
The vibration emission value
WARNING
during actual use of the power
tool can differ from the declared value
depending on the ways in which the tool is
used.
It is necessary to identify safety

measures to protect the oper-
ator that are based on an estimation of expo-
sure in the actual conditions of use.
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 pre-
liminary assessment of exposure.

The declared vibration emission level repre-
sents the main applications of the tool. How-
ever 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.
