countries, these values can vary.Please observe the article
number on the type plate of your machine. The trade names
of the individual machines may vary.
Noise/Vibration Information
The measured values of the machine are listed in the table
on page 9. Noise and vibrational values (vector sum of three
directions) determined according to EN60745.
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.
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.
