TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY:
1 Do not leave appliance when plugged in. Unplug from electrical
outlet when not in use and before servicing.
2 Do not use outdoors or on wet surfaces or to vacuum water or other
liquids – electric shock and personal injury could occur.
3 Do not allow to be used as a toy. Close attention is necessary when
used by or near children.
4 Do not allow use by anyone unable to operate the vacuum properly.
5 Use only as described in this manual. Use only with Dyson-
recommended attachments, accessories, and replacement parts.
6 Check to ensure your electricity supply corresponds to that shown on
the rating plate, which can be found on the base of the machine
between the wheels. The machine must only be used as rated.
7 If the machine is not functioning properly, has been dropped,
damaged, left outdoors, or immersed in liquid, contact the Dyson
Helpline at 1-
866-
693-
9766.
8 Do not use with a damaged cord or plug; do not pull or carry by the
cord; do not use the cord as a handle; do not close a door on the
cord or pull the cord around sharp edges or corners. Do not run the
machine over the cord. Keep the cord away from heated surfaces
and open flames.
9 Do not unplug by pulling on the cord. To unplug, grasp the plug,
not the cord.
10 Do not handle the plug or machine with wet hands.
11 Do not use the machine without the clear bin
TMand the filters
in place.
12 Do not put any objects into openings in the machine. Do not use
with any opening blocked; keep free of dust, lint, hair, and anything
that may reduce air flow.
13 Keep hair, loose clothing, fingers, and all parts of body away from
openings in the machine and moving parts such as the brushbar.
14 Do not use the machine to pick up sharp hard objects, small toys,
pins, paper clips, etc. They may damage the machine.
15 The use of an extension cord is not recommended.
16 Store the machine indoors. Put the machine away after use with the
cord wrapped safely to prevent tripping accidents.
17 Turn off all controls before unplugging.
18 Take extra care when cleaning on stairs; always work with the
machine at the bottom of the stairs. Keep vacuum on the floor. 
Do not put on chairs, tables, etc.
19 Do not pick up anything that is burning or smoking, such as
cigarettes, matches, or hot ashes.
20 Do not use to pick up flammable or combustible liquids, such as
gasoline, or use in areas where they may be present.
21 When vacuuming, certain carpets may generate small static charges
in the clear bin
TMor wand. These are not associated with the
electricity supply. To minimize any effect from this, do not put your
hand or insert any object into the clear bin
TMunless you have first
emptied it and rinsed it out with cold water.
22 Do not carry out any maintenance or repair work other than that
shown in this manual or advised by the Dyson Helpline.
23 Consult your flooring manufacturer’s instructions before vacuuming
and caring for your flooring, rugs, and carpets. Some carpets will
fuzz if a rotating brushbar is used when vacuuming. If this happens
we recommend vacuuming in bare floors mode and consulting with
your flooring manufacturer.
