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 time delay fuse. NOTE: Time delay fuses should be marked “D” in Canada and “T” in the US. 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.
MOTOR SPECIFICATIONS
Your machine is wired for 240, or 200/230/460 volt, 60 HZ alternating current. Before connecting the machine to the
power source, make sure the switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
This machine must be grounded while in use to protect the operator from electric shock.
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 instruction 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.
2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than
150 volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the
machine will have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like
the adapter illustrated in Fig. B may be used to connect this plug to a matching 2-conductor receptacle as shown
in Fig. B, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Whenever the
adapter is used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
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.
