Dry Vacuums
Electric shock could occur if used on wet surfaces.
DO NOT expose to rain – Store Indoors

When using this electric vacuum, basic precautions should always be followed, including the following:

  1. DO NOT leave the vacuum when plugged in. Unplug it from the outlet when not in use and before servicing.
  2. This is NOT a toy. Close attention is necessary when used around or near children.
  3. Use only as described in this safety manual. Use only manufacturer’s recommended attachments and accessories.
  4. DO NOT use this vacuum with damaged cord or plug. If the vacuum is not working as it should, because it has been dropped, damaged, left outdoors or dropped into water, contact an authorized service center or factory.
  5. DO NOT pull the vacuum by the cord, use cord as a handle, close a door on the cord or pull cord around sharp edges and corners. DO NOT run the vacuum over the cord. Keep cord away from heated surfaces.
  6. DO NOT handle the vacuum plug or the vacuum with wet hands.
  7. DO NOT unplug the vacuum by pulling on the cord. To unplug, grasp the plug, not the cord.
  8. DO NOT put any objects into openings. DO NOT use with any openings blocked; keep free of dust, lint, hair, and anything that may reduce air flow.
  9. Keep hair, loose clothing, fingers, and all parts of body away from the openings and moving parts.
  10. DO NOT pick up anything that is smoking or burning such as cigarettes, matches, or hot ashes.
  11. DO NOT use without dust bag and/or filters in place.
  12. Turn OFF all the controls before unplugging.
  13. DO NOT use where anesthetics or oxygen is used.

  16. Replace damaged or worn parts immediately with genuine original equipment parts to maintain safety and to protect your limited warranty.
  17. DO NOT use an extension cord unless absolutely necessary. If an extension cord is used, then the wire size must be #14 gauge or larger and should not exceed 50 feet in length. The extension cord must be three-wire type to insure GROUNDING protection.

This vacuum must be connected to a properly grounded outlet only. See grounding instructions below. If your vacuum has an outlet for a motorized power nozzle, always turn it OFF before connecting or disconnecting the motorized nozzle.
DANGER
Improper use of the grounding plug can result in a risk of electric shock.

GROUNDING INSTRUCTIONS

Electrical equipment 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 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 risk of electric shock. Check with 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.
