GROUNDING INSTRUCTIONS

• This appliance must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.
• This appliance is equipped with a cord having an equipment grounding conductor and ground plug.
• The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

WARNING:

• Improper connection of the equipment grounding conductor can result in a risk of electric shock.
• Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded.
• Do not modify the plug provided with the appliance.
• If it will not fit the outlet, have a proper outlet installed by a qualified electrician.
• This appliance is for use on a nominal 120-volt circuit, and has a grounded plug that looks like the plug illustrated in Fig.A.
• A temporary adapter that looks like the adapter illustrated in Fig.B, may be used to connect this plug to a two-pole 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 (Fig.A) is installed by a quali- fied electrician.
• The green colored rigid ear, lug, or the like extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover.
• Whenever the adapter is used, it must be held in place by a metal screw.
• DO NOT ATTEMPT TO REPAIR POWER CORD.

IN ALL CASES, MAKE SURE THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED.
NEVER REMOVE GROUNDING PRONG FROM POWER PLUG.

EXTENSION CORDS
Use only three-wire extension cords that have three-prong grounding-type plugs and three-pole receptacle that accepts the appliance’s plug. Replace damaged or worn cord  immediately.

Note
In Canada, the use of a temporary adapter is not permitted by the Canadian Electrical Code.
Servicing of double-insulated machines
In a double-insulated machine, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated machine, nor should a means for grounding be added to the machine. Servicing a double- insulated machine requires extreme care and knowledge of the system, and should be done only by qualified service personnel. Replacement parts for a double-insulated machine must be identical to the parts they replace.
