GROUNDING INSTRUCTIONS

DANGER
Improper use of the grounding plug can result in a risk of electric shock.

Electrical equipment must be grounded. If it should mal-function or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. This vacuum is equipped with a cord having an equipment-grounding conductor and grounding plug.
The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
If repair or replacement of the cord or plug is necessary, DO NOT connect the grounded wire to either flat blade terminal.
The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire.

GROUNDING METHODS

This electric equipment 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 adaptor that looks like the adaptor illustrated in (Fig B & C) may be used to connect this plug to a 2-pole receptacle as shown in (Fig B) if a properly grounded outlet is not available.
The temporary adaptor should be used only until a properly grounded outlet (Fig A) can be installed by a qualified electrician.
The green color rigid ear, lug or the like extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place by a metal screw (Fig C).

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 equipment. If it will not fit the outlet,have a proper outlet installed by a qualified electrician.
Note: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code.
