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 vibrational
load over the total working period.
Identify additional safety measures to protect
the operator from the effects of vibration
such as: Maintain the power tool and the
accessories, keep the hands warm, organiza-
tion of work patterns.
Emission values for sound and vibration
