Vibration
The declared vibration emission values stated in the
technical data and the declaration of conformity have been
measured in accordance with a standard test method
provided by EN 60745 and may be used for comparing
one tool with another. The declared vibration emission
value may also be used in a preliminary assessment of
exposure.
Warning! The vibration emission value during actual
use of the power tool can differ from the declared value
depending on the ways in which the tool is used. The
vibration level may increase above the level stated.
When assessing vibration exposure to determine safety
measures required by 2002/44/EC to protect persons
regularly using power tools in employment, an estimation
of vibration exposure should consider, the actual
conditions of use and the way the tool is used, including
taking account of all parts of the operating cycle such
as the times when the tool is switched off and when it is
running idle in addition to the trigger time.
