Emission values for sound
(Two-figure – specifications as per ISO 4871)
Extension cable.
If the use of an extension
cord is required, its length
and conductor cross-section must be ade-
quate for the application in order to prevent
a voltage drop in the extension cord, power
loss and overheating of the power tool.
Oth-
erwise, the extension cable and power tool
are prone to electrical danger, and the
working efficiency is decreased.
