Emission values for sound (Two-figure – specifications as per ISO 4871)
Sound emission
A-weighted emission pressure power level measured at the workplace L
(re 20 µPa), in decibels
Measuring uncertainty K
Measured A-weighted sound power level L
Measuring uncertainty K
C-weighted peak sound pressure level measured at the workplace L
in decibels
Measuring uncertainty K
pCpeak
REMARK: The sum of the measured emission value and respective measuring inaccuracy
represents the upper limit of the values that can occur during measuring.
Wear ear protection!
Measured values determined in accordance with the corresponding product standard.
Extension cord
If the use of an extension cord
WARNING
is required, its length and con-
ductor cross-section must be adequate for the
application in order to prevent a voltage drop in
the extension cord, power loss and overheating
of the power tool. Otherwise, the extension
cable and power tool are prone to electrical
danger, and the working efficiency is
decreased.
Recommended dimensions of extension cords
