A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should
be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-
prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the
machine to the power line, make sure the switch (s) is in the “OFF” position and be sure that the electric current is of
the same characteristics as indicated on the machine. All line connections should make good contact. Running on low
voltage will damage the machine.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
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. 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 IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This machine is
equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must
be plugged into a matching outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in risk of electric shock. The
conductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely
understood, or if in doubt as to whether the machine is
properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as shown in
Fig. A.
Repair or replace damaged or worn cord immediately.
POWER CONNECTIONS
MOTOR SPECIFICATIONS
Your machine either has a 230V, 60 HZ single phase motor (33-890, 33-895X and 33-891) or it has a 230V/460V 60
HZ three phase motor (33-892). Before connecting the machine to the power source, make sure the switch is off.
GROUNDING INSTRUCTIONS
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
3. 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.
THREE PHASE OPERATION
Three phase MACHINES are not supplied with a power
cord. They must be permanently connected to the
building electrical system and grounded according to
the National Electrical Code. Since they must be
permanently connected to the building electrical
system, extension cords cannot be used with three
phase MACHINES.
