IMPORTANT SAFEGUARDS
1. Disconnect power supply before servicing and/or cleaning the unit.
2. Do not leave appliance plugged in. Unplug from outlet when not in use or before servicing.
3. Do not use outdoors or on wet surfaces. Do not pick up water or wet materials.
4. Do not handle plug or appliance with wet hands.
5. Do not allow it to be used as a toy. Close attention is necessary when used by or near children.
6. Use only as described in this manual. Use only attachments recommended by manufacturer.
7. Do not use with damaged cord or plug. If the supply cord is damaged, it must be replaced by the manufacturer
or an Authorized Service Center or a similarly qualified person in order to avoid a hazard.
8. Do not pull or carry by the power cord as a handle, close door on cord, or pull the cord around sharp edges or
corners. Do not run appliance over the cord. Keep the cord away from heated surfaces.
9. Do not unplug by pulling the cord. To unplug, grasp the plug, not the cord.
10. Do not put any object into openings. Do not use with any opening blocked. Keep free from dust, lint, hair and
anything that may reduce air flow.
11. Keep hair, loose clothing, fingers, and all parts of body away from the openings and moving parts.
Do not use vacuum cleaner to pick up sharp, hard objects, small toys, pins, etc.
12. Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes.
13. Do not use to pick up flammable or combustible liquid or vapors such as gasoline or use in areas where they
may exist.
14. Do not use vacuum cleaner without dust bag and/or filters in place.
15. Always turn off all controls before unplugging.
16. Do not keep vacuum cleaner on chairs, tables, etc. Extra care must be taken when cleaning stairs.
17. Always unplug the unit or turn off the switch when the unit automatically stops unintentionally.
If you don’t, the cleaner could re-start unintentionally.
Polarized plug: This appliance has a polarized plug (one blade is wider than the other). As a safety feature to
reduce the risk of electric shock, this plug is intended to fit in polarized outlet only one way. If the plug does not fit
fully into the outlet, reverse the plug. If still does not fit, contact a qualified electrician. Do not attempt to defeat this
safety feature.
Thermal protector: This vacuum cleaner has a special thermostat that protects the vacuum cleaner in case of
motor overheating. If the cleaner suddenly shuts off, turn off the switch and unplug the vacuum cleaner. Check the
vacuum cleaner for a possible source of overheating such as a full bag, a blocked hose or clogged filter. If these
conditions are found, fix them and wait at least 30 minutes before attempting to use the vacuum cleaner. After the
30 minutes period, plug the vacuum cleaner back in and turn on the switch. If the vacuum cleaner still does not
run, contact a qualified electrician.
THIS PRODUCT IS FOR HOUSEHOLD USE ONLY
WARNING
Your safety is important to us. To reduce the risk of fire, electrical shock, injury to persons, or damage when
using your vacuum cleaner, follow basic safety precautions, including the following:
