Extension cable.
If the use of an extension cable
is required, its length and con-
ductor cross-section must be adequate for the
applicational case, in order to prevent a volt-
age drop in the extension cable, power loss
and overheating of the power tool.
Other-
wise, the extension cable and power tool are
liable to electrical danger, and the working
efficiency is impaired.
Recommended dimensions of extension
cables at an operating voltage of 120 V – sin-
gle-phase a. c., with only one power tool
KBH25 connected:
Intended use of the power tool:
hand-held core drill for drilling in metal and
for tapping in weather-protected environ-
ments without water supply using the applica-
tion tools and accessories recommended by
FEIN.
Do not use the power tool in a drill stand.
Operation of the power tool off power generators.
This power tool is also suitable for use
with AC generators with sufficient power
output that correspond to the Standard
ISO 8528, design type G2. This Standard is
particularly not complied with when the so-
called distortion factor exceeds 10 %. When
in doubt, please refer to the generator
instruction/specification guide.
Operating the power tool off
power generators whose no-
load speed exceeds the voltage value on the
type plate of the power tool is prohibited.
