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 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.
