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.

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.
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
