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 out-
let 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 ser-
vice personnel; and after re-connection, the machine should
comply with all local codes and ordinances.
