Dustbag indicator and changing the dustbag For peak performance the dustbag should be changed when full. The mechanical dustbag indicator window will gradually turn red when filling and completely red when full. If the dustbag should get broken in the cleaner, take cleaner to service centre for cleaning. This is not covered by the guarantee. The dustbag full indicator may signify that the bag is blocked (occasionally caused by finer dust) which will cause loss of suction and may result in overheating. If this occurs change the bag even if it is not full. DO NOT VACUUM VERY FINE DUST (PLASTER, CEMENT, COLD CINDERS...). To check the dustbag, the cleaner must be switched on, with all attachments connected but the nozzle does not have to be placed on the floor. To change the dustbag 7 Open the cleaner cover. 8 Remove the dustbag from its holder. Insert the new dustbag into the holder. Close the cover (8, 7). We recommend the dustbag is changed after using a carpet cleaning powder or if there is a bad smell from the cleaner. Note: Only use original dustbag and filters Dustbag (Ref. number: E62n) Dustbag safety device To avoid damaging the cleaner, do not use it without a dust bag. A safety device is fitted which prevents the cover closing without a dust bag in place. Do not attempt to force cover shut. Changing/cleaning the filters Never use the cleaner without the filters in place. The filters should be changed/cleaned approximately every fifth dustbag. To maintain Motor Protection filter 7 Open the cleaner cover. 9 Remove the filter unit, rinse the filter under warm tap water only and dry the filter completely (9,12,13). The original filtering performance is now restored. Replace the unit back into the cleaner and close cover ensuring it is securely in place and the cover is properly closed. (9,7) Latest every second year replace the old filter with a new one.

Troubleshooting
Dustbag: please check that the dustbag is placed correctly and ensure that it is not jammed (1). Power: if the electric power does not come on, disconnect from mains and check plugs, cable and fuses where appropriate. The cleaner may switch itself off in event of severe blockage or excessively dirty filters. In such cases, disconnect from mains and allow to cool for 30 minutes. Clear blockage and/or replace filter(s) and restart. The clearing of blocked hoses is not covered by the guarantee. To avoid blockages and maintain suction efficiency, the floor nozzles should be cleaned regularly using the hose handle. Please see additional Volta information towards the back of this booklet. Water: if water is sucked into the cleaner the motor must be changed at a service centre. This is not covered by the guarantee.
