The brush bar will always default to ‘ON’ (spinning) each time you switch the appliance ‘ON’ and recline it for cleaning.
The brush bar will not rotate when the appliance is upright.
To switch the brush bar ‘OFF’ (e.g. for delicate rugs and hard floors):
- switch the appliance ‘ON’
- recline the appliance
- press the brush bar ‘ON/OFF’ button – the brush bar will stop spinning.
The brush bar will automatically stop if it becomes obstructed. See ‘Brush bar – clearing obstructions’.
Before vacuuming your flooring, rugs and carpets, check the manufacturer’s recommended cleaning instructions.
Some carpets may fuzz if a rotating brush bar is used when vacuuming. If this happens, we recommend vacuuming in ‘hard floor’ mode and consulting with the flooring manufacturer.
The brush bar on the appliance may damage some carpet types. If you are unsure, turn ‘OFF’ the brush bar.

LOOKING AFTER YOUR DYSON APPLIANCE

Do not carry out any maintenance or repair work other than that shown in this Dyson Operating Manual, or advised by the Dyson Helpline.
Only use parts recommended by Dyson. If you do not this could invalidate your warranty.
Store the appliance indoors. Do not use or store it below 32°F (0°C). Ensure the appliance is at room temperature before operating.
Clean the appliance only with a dry cloth. Do not use any lubricants, cleaning agents, polishes or air fresheners on any part of the appliance.
If used in a garage, always wipe the base plate, ball and stabilizer wheels with a dry cloth after vacuuming to clean off any sand, dirt or pebbles that could damage delicate floors.

Dyson DC 40 Upright Vacuuming Cleaner

Do not use without the clear bin and filters in place.
Fine dust such as plaster dust or flour should only be vacuumed in very small amounts.
Do not use the appliance to pick up sharp hard objects, small toys, pins, paper clips, etc. They may damage the appliance.
When vacuuming, certain carpets may generate small static charges in the clear bin or wand. These are harmless and are not associated with the main electricity supply. To minimize any effect from this, do not put your hand or insert any object into the clear bin unless you have first emptied it and rinsed it out with cold water (see ‘Cleaning the clear bin’).
Powerful suction can cause the hose to ‘pull back’ – please take care.
Do not work with the appliance above you on the stairs.
Do not put the appliance on chairs, tables, etc.
Before vacuuming highly polished floors, such as wood or linoleum, first check that the underside of the floor tool and its brushes are free from foreign objects that could cause marking.
Do not leave the cleaner head in one place on delicate floors.
Do not use this vacuum cleaner outdoors. The Dyson Car Cleaning Kit (Model 08909) is intended for use only inside a garage.

EMPTYING THE CLEAR BIN

Empty as soon as the dirt reaches the level of the MAX mark – do not overfill.

To release the dirt, press all the way down on the red button at the rear of the carrying handle on the cyclone.

Remove the clear bin carefully.
Seal the bag tightly, dispose as normal.

CLEANING THE CLEAR BIN

Ensure the clear bin is completely dry before replacing.
Do not use detergents, polishes or air fresheners to clean the clear bin.
Do not put the clear bin in a dishwasher.
Do not immerse the whole cyclone unit in water or pour water into the cyclones.

- close the clear bin base so it clicks into place
- push the cyclone and clear bin unit into the main body of the appliance; it will click into place
- ensure the cyclone and clear bin unit is secure.

WASHING YOUR FILTERS

Your appliance has two washable filters, located as shown.

The filters may require more frequent washing if vacuuming fine dust.

LOOKING FOR BLOCKAGES

Switch ‘OFF’ and unplug before looking for blockages. Failure to do so could result in personal injury.
Look for blockages in the wand, airways and cleaner head.
To remove the base plate to access an obstruction, see ‘Base plate – disassembly/reassembly’.
To look for blockages in the airway between the ball and the cleaner head you will need to remove the cleaner head: see ‘Base plate – disassembly/reassembly’ below on how to do this.
Beware of sharp objects when checking for blockages.
Refit all parts securely before using.
Clearing blockages is not covered by your warranty.

DYSON CLEARING BLOCKAGES

THERMAL CUT-OUT

This appliance is fitted with an automatically resetting thermal cut-out.
Large items may block the tools or wand inlet. If any part becomes blocked the appliance may overheat and automatically cut-out.
Switch ‘OFF’ and unplug. Leave to cool down for 1-2 hours before checking the filters or for blockages.
Clear any blockage before restarting.
Clearing blockages is not covered by your warranty.

BRUSH BAR CLEARING OBSTRUCTIONS

If your brush bar is obstructed, it may shut off. If this happens, you will need to remove the blockage.
Switch ‘OFF’ and unplug before proceeding. Failure to do so could result in personal injury.
Beware of sharp objects when clearing obstructions.
If you still cannot clear the obstruction, please follow the instructions below to remove the base plate. This gives more access to the obstruction. Alternatively, contact a Dyson expert on the Dyson Helpline or visit the website. Clearing brushbar obstructions is not covered by your warranty.

BASE PLATE

DISASSEMBLY/REASSEMBLY

Switch ‘OFF’ and unplug before proceeding. Failure to do so could result in personal injury.
Lie the appliance on its front.
Detach the red ‘C’ clip, which is on the connection between the cleaner head and the appliance. It is quite firm, but do not pull it off roughly. Use a constant, firm pressure.
Pull the cleaner head away from the appliance. Use a constant, firm pressure.
At each end of the cleaner head are two levers:
- swing them out at right angles
- the base plate will disengage
- lift up the top edge (of the base plate), so it rotates to the upright position
- lift out.
Beware of sharp objects when clearing obstructions.
To refit the base plate:
- fit the 3 lugs on the lower edge of the base plate into the 3 slots in the base of the cleaner head
- swing the upper edge of the base plate down; it will click into place.
To secure the base plate push both levers back into position so they are flush with the surface of the cleaner head.
Refit the red ‘C ‘clip onto the cleaner head. The flatter edge of the clip fits against the cleaner head. It is easier to slide one lug into its slot before the other.
Lie the appliance on its back.
Attach the cleaner head by sliding it on to the connections on the lower front part of the ball. Ensure the electrical plug on the cleaner head fits into the twin-block connection on the body of the appliance, which is directly above the airway.
Push firmly: the cleaner head will click into place.
