Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire exten-
sion cord which has a 3-prong grounding type plug and matching receptacle which will accept the
machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current
of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and over-
heating. Fig. D, shows the correct gauge to use depending on the cord length. If in doubt, use the next
heavier gauge. The smaller the gauge number, the heavier the cord.

3. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating between
150 - 250 volts, inclusive:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. C, the
machine will have a grounding plug that looks like the
plug illustrated in Fig. C. Make sure the machine is con-
nected to an outlet having the same configuration as the
plug. No adapter is available or should be used with this
machine. If the machine must be re-connected for use
on a different type of electric circuit, the re-connection
should be made by qualified service personnel; and
after re-connection, the machine should comply with all
local codes and ordinances.
