REMARK: The sum of the measured emission value and respective measuring inaccuracy rep-

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.
