Extension cable.
If the use of an extension cord
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.
Recommended dimensions of extension
cables at an operating voltage of 120 V – sin-
gle-phase a. c., with only one power tool MSf,
MSfo, MSfov connected:
Intended use of the power tool:
Hand-guided angle grinder for use in
weather-protected environments with the
application tools and accessories recom-
mended by FEIN.
