DUST COMPARTMENT OPERATION (Fig. 7)

When the orange sign ⑥ appears continuously in the window, empty the dust compartment.

Never allow the dust compartment to become so full that the dirt will block the passage to the compartment.

Empty the dust compartment frequently when using the cleaner on new carpets, due to rapid accumulation of carpet fluff. And maintain the filters along Filter Care on Page 6.

In case the orange sign is still visible after emptying the dust compartment, turn the cleaner off, unplug the cord and check whether the duct hose is clogged. If so remove blockages.

NOTE: If the cleaner is used when the orange sign appears in the window, it will not draw enough air and the motor may overheat and may eventually burn out.

CARRYING HANDLE (Fig. 8)

Tomove your cleaner from room to room, carry it by the carrying handle ⑦ on the back of the cleaner or roll it on the rear wheels.

EDGE CLEANING (Fig. 8)

Brushed edge cleaning is provided on the both sides of the cleaner to remove imbedded dirt in carpet close to the skirting board or wall.

Guide each side of the cleaner parallel to the wall or furniture.

FRONT EDGE CLEANING (Fig. 9)

The front edge cleaning is a special head function that provides good performance at the corner and wall edges of a room.

How to empty the dust compartment

1) Empty the dust compartment before dust reaches the max line.
2) If you continue using the cleaner, the suction power will be diminished due to dust clogging the filter.
3) Please remove the dust.

NOTE:

Switch off the power and remove the mains plug from the socket before emptying the dust compartment.

How to dispose of the dust (Fig. 17)

1) Press the clamp of dust case.
2) Remove the dust case from the lower side.

NOTE:

1) When you remove the dust compartment from the body, don't press the open button on the compartment. If you do so, the dust will spill out from the compartment.
2) When using the cleaner, don't remove the dust compartment from the body.
3) Be careful when removing the dust compartment not to spill dust.
4) Put the whole dust compartment into a poly bag and press the open button to empty dust into the poly bag.
5) Turn the dust compartment downwards, push the open button for the lid of the dust compartment, to release the dust.
6) Remove dust around the mesh filter and under mesh filter.

Filter care (Fig. 18)

It is recommended that the filter is cleaned once or twice a month to ensure optimum suction power:

1) Empty the dust compartment as described in the previous section.
2) Take off the filter supporter from the filter holder.
3) Wash the filter in tepid water or a neutral detergent. If detergent is used, rinse it out thoroughly.
4) Allow the filter to dry naturally.

NOTE:

1) Don't wash in boiling water or in a washing machine.
2) Don't dry over a fire, in hot sunlight or in a tumble dryer.
3) If the filter is used when wet, suction will be impaired and the motor may be damaged.

HOW TO MAINTAIN CLEANING EFFICIENCY

●The plug of the power supply cord should be removed from the socket outlet before cleaning the appliance or undertaking maintenance operations.
●The supply cord on this appliance can only be replaced by the use of special tools and if it is damaged the appliance must be returned to the manufacturer or an accredited service agent for repair.
●Empty the dust compartment before it is filled excessively.
- If the rotary brush becomes jammed by picking up large solid objects, bulky matter or the like, take it out after unpluging the cord. Remove any threads and long strings entwined round the rotary brush after cutting through.
●Only Hitachi special composition carbon brushes must be used in this cleaner. Replacement of the brushes must be carried out by an Hitachi dealer/service center.
● To clean the cleaner body and attachments, wipe with a soapsuds-soaked cloth. Avoid using alcoholic content liquids.

TO AVOID ACCIDENTS

●Always disconnect cord from electrical outlet before servicing the cleaner.

- Keep fingers, hands, feet and hair away from revolving rotary brush.

●Do not pick up matches, fireplace ashes or smoking material with the vacuum cleaner as a possible fire hazard may result.

● Avoid picking up sharp objects. They may damage the vacuum cleaner and the bag.

●Do not use the cleaner to pick up wet dirt, and avoid using it in a wet and moist place as moisture may damage the motor and other mechanical parts.

- Do not block the air flow. Any blockages or obstructions to the nozzle, hose, etc. or the exhaust air outlet can cause loss of power and motor overheating.

●Do not run the cleaner over cord. It may damage insulation.

● Avoid cleaning the switch and receptacle parts with wet cloth and splashing water on it as moisture may cause a short circuit.

- Your vacuum cleaner is not a toy. Do not allow children to play with it. Do not leave the vacuum cleaner connected to and electrical outlet unattended.

● Warning: Electric shock could occur if used outdoors or on wet surfaces.

● Warning: During use of the (accessory) tools, the rotary brush will continue to rotate and care must be taken to keep hands and the mains lead clear of the underside of the vacuum cleaner.

● Warning: When using accessory tools, the rotary brush will continue to rotate, so care must be taken not to leave the vacuum cleaner standing on an uneven surface, e.g. stairs, as this may result in damage to a carpet or other surface.

● Warning: Do not leave the vacuum cleaner running continuously on one part of a floor surface, e.g. when answering the phone, as this may result in damage. Switch off the vacuum cleaner.

IMPORTANT

The mains lead on this equipment is supplied with a moulded plug incorporating a fuse, the value of which is indicated on the pin face of the plug. Should the fuse need to be replaced, an ASTA or BSI approved BS 1362 fuse must be used of the same rating. If the fuse cover is detachable never use the plug with the cover omitted. If a replacement fuse cover is required, ensure it is of the same colour as that visible on the pin face of the plug. Fuse covers are available from your dealer.

DO NOT cut off the mains plug from this equipment. If the plug fitted is not suitable for the power points in your home or the cable is too short to reach a power point, then obtain an appropriate safety approved extension lead or consult your dealer.

Should it be necessary to change the mains plugs, this must be carried out by a competent person, preferably a qualified electrician.

If there is no alternative to cutting off the mains plug, ensure that you dispose of it immediately, having first removed the fuse, to avoid a possible shock hazard by inadvertent connection to the mains supply.

IMPORTANT

The wires in the mains lead are coloured in accordance with the following code:

Blue=Neutral, Brown=Live

As these colours may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

The wire coloured BLUE must be connected to the terminal marked with the letter N or coloured BLUE or BLACK. The wire coloured BROWN must be connected to the terminal marked with the letter L or coloured BROWN or RED.

On no account connect either of these wires to the terminal marked E or by the earth symbol or coloured green or green and yellow.
