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.
