An estimation of the level of exposure to vibration
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 such as: main-
tain the tool and the accessories, keep the hands
warm, organisation of work patterns.
typical A-weighted sound levels:
L = sound pressure level
pA
L = sound power levell
WA
K , K = unsafe (noise level)
pA WA
Wear hearing protection!
Measured values established according to
EN 60745.
*1 Impuls and Contact models:
High-energy high-frequency interferences can
cause deviations in working speed of up to 20%.
The speed returns to normal as soon as the
interference has faded away.
The technical specifications quoted are subject to
tolerances (in compliance with the relevant valid
standards).
