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.
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.
qualified electrician check the receptacle.
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,
