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 hearing protection!
Measured values determined in accordance with the corresponding product standard.
Extension cable.
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 over-
heating of the power tool. Otherwise, the
extension cable and power tool are prone to
electrical danger, and the working efficiency is
decreased.
