Emission values
Using these values, you can estimate the
emissions from this power tool and compare these
with the values emitted by other power tools. The
actual values may be higher or lower, depending on
the particular application and the condition of the
tool or power tool. In estimating the values, you
should also include work breaks and periods of low
use. Based on the estimated emission values,
specify protective measures for the user - for
example, any organisational steps that must be put
in place.
Vibration total value (vector sum of three directions)
determined in accordance with EN 60745:
a = Vibration emission value
h, ID
(impact drilling into concrete)
a = Vibration emission value
h, D
(drilling into metal)
a = Vibration emission level (screwing
h, S
without impact)
K = Uncertainty (vibration)
h, ...
Typical A-effective perceived sound levels::
L = Sound pressure level
pA
L = Acoustic power level
WA
K , K = Uncertainty (noise level)
pA WA
During operation the noise level can exceed
80 dB(A).
