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.
