** The sound intensity level for the operator may
exceed 78.5dB and ear protection measures are
necessary.
*** The declared vibration value has been measured
in accordance with a standard test method and
may be used for comparing one tool with another.
The declared vibration value may also be used in a
preliminary assessment of exposure.
WARNING! The vibration emission value during
actual use of the tool can differ from the declared
value depending on the ways in which the tool is used.
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
operating cycle such as the times when the tool is
switched off and when it is running idle in addition to
the trigger time).
