Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Cutting concrete slab:
Vibration emission value
Uncertainty K: = 1.5 m/s

The declared vibration total value has been measured in
accordance with a standard test method and may be used
for comparing one tool with another.
It may also be used in a preliminary assessment of
exposure.
WARNING
○ The vibration emission during actual use of the power
tool can diff er from the declared total 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).
