The sound values have been determined according to noise test code given in Directive 2000/14/
EC, Annex V & Directive 2005/88/EC, using the basic standards EN ISO 3744:1995 and EN
3744:2010. The sound intensity levels for the operator may exceed 80 dB(A) and ear protection
measures are necessary. The declared vibration total value has been measured in accordance
with a standard test method and may be used for comparing one machine with another; The
declared vibration total value may also be used in a preliminary assessment of exposure.
Warning : The vibration and noise emissions during actual use of the power tool can dier from
the declared values depending on the ways in which the tool is used especially what kind of
workpiece is processed;
Warning : The need to identify safety measures to protect the operator that are based on
an estimation of exposure in the actual conditions of use (taking account of all parts of the
