Use only 3-wire extension cords that have 3-prong grounding
type plugs and matching 3-conductor receptacles that accept
the machine’s plug.
Repair or replace damaged or worn cord immediately.
SHOCK HAZARD. In all cases, make certain
that the receptacle in question is properly grounded. If
you are not sure, have a qualified electrician check the
receptacle.
2. 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. A or Fig. B, the machine
will have a grounding plug that looks like the plug illustrated in
Fig. A or Fig. B. 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 the National Electric Code and all local codes and
ordinances.
NOTE: The plug for the 3 HP model looks like the plug
illustrated in Fig. A. Make sure the 3 HP machine is connected
to an outlet having the same configuration as the plug.
NOTE: The plug for the 5 HP model looks like the plug
illustrated in Fig. B. Make sure the 5 HP machine is connected
to an outlet having the same configuration as the plug.
3. Permanently connected machines:
If the machine is intended to be permanently connected, all
wiring must be done by a qualified electrician and conform to
the National Electric Code and all local codes and ordinances.
THREE PHASE OPERATION: Three phase machines are
not supplied with a power cord and must be permanently
connected to a building’s electrical system. Extension cords
can’t be used with a three phase machine.
LVC MAGNETIC MOTOR CONTROL: If you purchased a
machine that has a Low Voltage Magnetic Motor Control
System, refer to its instruction manual for installation guidance.

EXTENSION CORDS
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. C, 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.
