DUST BAG FULL INDICATOR

When the orange sign appears in the window continuously, change the dust bag.

Never allow the bag to become so full that the dirt may choke the passages to the bag.

Change the bag frequently when using the cleaner on new carpets, due to rapid accumulation of carpet fluff. In case the orange sign is still visible after changing the bag, 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

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.
  ● Change the dust bag before it is excessively filled.
• 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.
- Be sure to replace a new paper bag after disposing of the full one. There is a device which prevents the bag compartment lid from being closed when the paper bag has not been replaced. Do not tamper with this to use without bags as dust will be sucked directly into the mechanical parts and may damage the motor.
- 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 clener 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 an 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 main slead 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. Shoud 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.
