Noise/Vibration Information
The measured values of the machine are listed in the table on
page 133.
Noise and vibrational values (vector sum of three directions)
determined according to EN 60745.
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 expo-
sure.
The declared vibration emission level represents the main ap-
plications 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 in-
crease 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 sig-
nificantly reduce the exposure level over the total working pe-
riod.
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 pat-
terns.
