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:

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

• Do not use it outdoors or on wet surfaces.

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

• Do not unplug by pulling on the cord. To unplug, grasp the plug, not the cord.

• Do not handle the plug or appliances with wet hands.

• Do not put any objects into openings.
  Do not use any opening blocked; keep free of dust, lint, hair, and anything that may reduce airflow.

• Keep hair, loose clothing, fingers, and all parts of the 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 it without a 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 the 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 gauge. The smaller the gauge 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, and fire, and increases the risk of burning.

• To reduce the risk of disconnection of the appliance cord from the extension cord during operation, secure the extension cord to the appliance plug as described in the manual.

GROUNDING INSTRUCTIONS

MODEL: C-CPU4T
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.

The nozzle hose carries the dirt from the nozzle to the vacuum bag. If the hose should become clogged:

1. Pull out and turn the lid of the accessory attachment opening.
   Remove the clog or blockage (Fig. 1).

2. If the above step is not enough, remove the hose cuff from the attachment port inlet (Fig. 2). If you haven’t located the clog, turn the vacuum cleaner over and remove the bottom plate. Check the nozzle inlet tube for obstructions (Fig. 3). Clear the tube and reinstall the bottom plate.
   

THERMAL FUSE PROTECTION

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 problems (over-filled bag, clog in the hose, clogged filters, etc.).
3. Correct problem.
4. Locate the “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 another pointy object, push the reset button.
