Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire
extension 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 overheating. 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
connected 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.
IN ALL CASES, MAKE CERTAIN THE

RECEPTACLE.
4. Permanently connected machines:
If the machine is intended to be permanently connected,
the machine should be connected to a grounded metal
permanent wiring system, or to a system having an
equipment-grounding conductor.

If the motor on your machine is wired for 200V, 230V, or 460V, three phase, the necessary wiring from the starter to the
power should be completed by a qualified electrician.
