IMPORTANT SAFETY INSTRUCTIONS

When using an electrical appliance, basic precautions should always be followed, including the following:

READ ALL INSTRUCTIONS BEFORE USING THIS APPLIANCE

WARNING: To reduce the risk of fire, electric shock, or injury:

• Do not leave appliance when plugged in. Unplug from outlet when not in use and
before servicing.

• Do not use outdoors or on wet surfaces.

• Connect to a properly grounded outlet only. See grounding instructions.

• Do not allow to be used as a toy. Close attention is necessary when used by or near children.

• Keep hair, loose clothing, fingers, feet and all parts of body away from openings, rotating
agitator and other moving parts.

• Do not operate cleaner in bare feet or when wearing open toe shoes or sandals.

• Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes.

• Do not use to pick up flammable or combustible liquids such as gasoline, or fine wood
sandings, or use in areas where they may be present.

• Avoid picking up hard, sharp objects with the cleaner. They may damage the cleaner and
the bag.

• Do not use without dust bag or dirt cup in place. Change bag frequently when picking up
very fine materials such as powder.

• Use extra care when cleaning on stairs.

• Do not put any object into openings. Do not use with any opening blocked; keep free of
dust, lint, hair, or anything that may reduce air flow.

• Do not pull or carry by cord, use cord as a handle, close door on cord or pull cord around
sharp edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.

• Always disconnect cord from electrical outlet before servicing the cleaner.

• Unplug cleaner when not in use. Turn off all controls before unplugging.

• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord. Never handle
plug or appliance with wet hands.

• The use of an extension cord is not recommended. If an extension cord is absolutely
necessary, use at least a 16 gauge 3-wire cord which has a 3-prong grounding type plug and
a 3-pole receptacle that accepts the machine plug.

• Do not use with damaged cord or plug. If appliance is not working as it should, has been
dropped, damaged, left outdoors, or dropped into water, take it to a Hoover Commercial
Service Center or Authorized Hoover Commercial Warranty Service Distributor.

• Use only as described in this manual. Use only manufacturer's recommended attachments.

DANGER ‑ Improper connection of the equipment-

grounding conductor can result in the 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
grounding plug that looks like the plug in sketch (1).

A temporary adapter (D) may be used to connect this plug to a
2-pole receptacle (E) if a properly grounded outlet is not available.

The temporary adapter should be used only until a properly grounded outlet (B) can be installed by a
qualified electrician.

The green colored rigid ear, lug, or the like (F) extending from the adapter must be connected to a
permanent ground (G) such as a properly grounded outlet box cover.

Whenever the adapter is used, it must be held in place by a metal screw.

Note: In Canada, the use of a temporary adapter is not permitted by the Canadian Electrical Code.

Grounding Instructions

This appliance must be grounded.
If it should malfunction or breakdown, grounding provides a

path of least resistance for electrical current to reduce the risk of
electric shock.

This appliance is equipped with a cord having an equipment­grounding conductor (C) and grounding plug (A).

The plug must be plugged into an appropriate outlet (B) that
is properly installed and grounded in accordance with all local
codes and ordinances.
