Alternating current
The technical specifications quoted are subject to
tolerances (in compliance with the relevant valid
standards).
Emission values
These values make it possible to assess the
emissions from the power tool and to compare
different power tools. Depending on the operating
conditions, the condition of the power tool or the
accessories, the actual load may be higher or lower.
For assessment purposes, please allow for breaks
and periods when the load is lower. Based on the
adjusted estimates, arrange protective measures
for the user e.g. organisational measures.
Vibration total value (vector sum of three directions)
determined in accordance with EN 60745:
a = Vibration emission value
h, HD
(hammer drilling into concrete)
a = Vibration emission value
h, Cheq
(chiselling)
K =Uncertainty (vibration)
h,HD/Cheq
Typical A-effective perceived sound levels:
L = Sound pressure level
pA
L = Acoustic power level
