This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.
Consult a qualified electrician or service person if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.
Use of an extension cord is not recommended. If the power supply cord is too short, have a qualified electrician or service person install an outlet near the appliance.
If it is necessary to use an extension cord, use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot socket that will accept the plug on the appliance. The marked rating of the extension cord must be equal to or greater than the electrical rating of the appliance.
Ensure proper ground exists before use.

Keep the electrical power cord dry and do not pinch or crush it in any way.
Improper use of grounding can result in a risk of electric shock.
A short power supply cord is provided to reduce the risks resulting from becoming entangled in or tripping over a longer cord.
Longer cord sets or extension cords are available and may be used if care is exercised in their use.
If a long cord or extension cord is used, (1) the marked electrical rating of the cord set or extension cord must be at least as great as the electrical rating of the appliance, (2) the extension cord must be a grounding-type 3-wire cord, and (3) the longer cord should not be draped over a counter or table where children could pull on it, or located where it could present a trip hazard.
