DeWalt DCH273 User Manual

ENGLISH
An estimation of the level of exposure to vibration and/
or noise 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 and/or noise such
as: maintain the tool and the accessories, keep the
hands warm (relevant for vibration), organisation of
workpatterns.
The vibration and/or noise emission level given in this
information sheet has been measured in accordance with
a standardised test given in EN62841 and may be used to
compare one tool with another. It may be used for a preliminary
assessment ofexposure.

WARNING: The declared vibration and/or noise 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 and/or
noise emission may differ. This may significantly increase
the exposure level over the total workingperiod.
