IMPORTANT SAFETY INSTRUCTIONS
When using an electrical appliance, basic precautions
should always be followed, including the following:
READ ALL INSTRUCTIONS BEFORE USING THIS
APPLIANCE. FOR HOUSEHOLD USE ONLY.
IMPORTANT:
The manufacturer cannot accept responsibility for damage
caused when the appliance is not used according to the instructions, or for uses other
than those for which it was intended.
WARNING: To reduce the risk of fire, electric shock, damage or injury:
SAVE THESE INSTRUCTIONS
• 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.
• Do not allow to be used as a toy. Close
attention is necessary when used by or
nearchildren.
• Use only as described in this manual.
• 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, return
it to the distributor where purchased
for service.
• Do not pull or carry by cord, use cord
as a handle, close a door on the cord,
or pull cord around sharp edges or
corners. Do not run appliance over
cord. Keep cord away from heated
surfaces.
• Do not unplug by pulling on cord. To
unplug, grasp the plug, not the cord.
• Do not handle plug or appliance with
wethands.
• Do not put any object into openings.
Do not use with any opening blocked;
keep free of dust, lint, hair and
anything that may reduce air flow.
• Keep hair, loose clothing, fingers and
all parts of body away from openings
and movingparts.
• Do not pick up anything that is
burning or smoking, such as cigarettes,
matches or hotashes.
• Do not use without vacuum bag in place.
• Turn off all controls before unplugging.
• Use extra care when cleaning on stairs.
• Do not use to pick up flammable or
combustible liquids such as gasoline
or use in areas where they may be present.
• Do not attempt to service the unit
while appliance is plugged in.
• Connect to a properly grounded outlet
only. See Grounding Instructions.
• Make sure your extension cord is
in good condition and is the correct
size for your appliance, i.e. 16 AWG.
If in doubt, use the next heavier
gage. The smaller the gage number,
the heavier the cord. An undersized
extension cord will cause a drop in
line voltage resulting in loss of power
and overheating.
• Use only three-wire outdoor extension
cords that have three-prong grounding
plugs and grounding receptacles that
accept the appliance’s plug.
• To reduce the risk of personal injury
due to a loose electrical connection
between the appliance’s plug and
extension cord, firmly and fully attach
the appliance plug to the extension
cord. Periodically check the connection
while operating to ensure it is fully
attached. Do not use an extension
cord that provides a loose connection.
A loose connection may result in
overheating, fire, and increases the
risk of a burning.
• To reduce the risk of disconnection
of the appliance cord from the extension
cord during operating, secure the
extension cord to the appliance plug
as described in the manual.

GROUNDING INSTRUCTIONS
MODELS: CPU-3QD and CPU-3N
This product is equipped with a polarized
alternating current line plug (a plug having
one blade wider than the other). This
plug fits into the power outlet only one
way. This is a safety feature. If you are
unable to insert the plug fully into the
outlet, try reversing the plug. If the plug
still does not fit, contact an electrician to
replace the obsolete outlet. Do not defeat
the safety purpose of the polarized plug.
MODELS: CPU-4N and CPU-4T
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
grounding plug. The plug must be
plugged into an appropriate outlet that
is properly installed and grounded in
accordance with all local codes and
ordinances.
This appliance is for use on a nominal 120 volt circuit and has a grounding attachment
plug. Make sure that the appliance is connected to an outlet having the same configuration
as the plug. No adapter should be used with this appliance.
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 vacuum cleaner comes equipped with a Manual Reset Thermal Fuse Protector.
The thermal protector is designed to protect the vacuum cleaner from overheating
due to a cutoff in airflow (i.e. clogged hose, operating the vacuum without a bag).
Should this situation occur, the thermal fuse protector will safely shut off the vacuum
cleaner to avoid any potential damage.
To Reset the Thermal Fuse
1. Unplug the vacuum cleaner.
2. Check for problem (over-filled bag, clog in hose, clogged filters, etc.).
3. Correct problem.
4. Locate “tripped” fuse — the small black button located on the lower left side
on the back of the main body (roughly one inch to the right of the left wheel).
5. Using a pencil, paper clip, or other pointy object, push the reset button.
6. Plug vacuum cleaner in and begin using.
Please return to a Service Center if the problem continues or if you have any questions.
