Extension cord
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 overheating
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 cords
at an operating voltage of 120 V – single-phase
a. c., with only one power tool
JCM312U/JCM312auto connected:
Intended use of the power tool.
Magnetic base drill for drilling with annular
tools and twist drill bits, reaming, countersin-
king and tapping on materials with surfaces
suitable for magnets in weather-protected
environments using the cutting tools and
accessories recommended by the manufactu-
rer.
Operation of the power tool off power generators.
Operate the power tool only off
a.c. generators with sufficient power
output that do not have any distortion of the
voltage curve.
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.
