The declared vibration emission value has been
•
measured in accordance with the standard test
method and may be used for comparing one tool
ENG104-1
with another.
The declared vibration emission value may also be
•
used in a preliminary assessment of exposure.
WARNING:
The vibration emission during actual use of the
•
power tool can differ from the declared emission
value depending on the ways in which the tool is
used.

Be sure to identify safety measures to protect the
•
operator that are based on an estimation of
sum)
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).
