5. Live conductors must not be vacuum cleaned by themachine for dry dust before their current has been switchoff. This is to avoid creating a short-cut through the dustremaining in the nozzles and tubes.6. The machine must not be used for picking up combustibleor explosive materials, nor should it be used in anexplosive atmosphere.7. Under no circumstances should the machine be used forpicking up hot material. In particular the machine must notbe used for cleaning open and closed fireplaces, ovens orsimilar that contain warm or glowing ashes.8. The machine must not be used if the electrical cordshows any sign of damage. Regularly inspect the cord fordamage, in particular if it has been crushed, shut in a dooror run over.9. The machine must not be used if it is faulty.10. Do not unplug by pulling on cord. To unplug, grasp theplug, not the cord.11. Always turn off this appliance before connecting ordisconnecting motorised nozzle.12. When repairing or replacing the cord, the same type ofcord as originally supplied with the machine must beused. This cord can be supplied by NILFISK.13. The plug must always be removed from the socket outletbefore starting any service work of the machine or thecord.14. Repair of the electrical unit with motor or the cord mustonly be carried out by a skilled or instructed person afterhaving disconnected the main switch installed prior to themachine or after having removed the plug from the currentsocket.15. No changes or modifications to the mechanical orelectrical safety devices should be made.Instructions for useBefore using the machine make sure that the frequency andvoltage shown on the rating plate corresponds with the mainsvoltage.Specifications and details are subject to change without priornotice.On/offAttaching the power cord 80P/90CPlace the appliance plug of the cord in the motor socket, only80P. Pressing the button turns the motor on and off alternately.Q Detaching the power cord 80P/90CDo not roll the cord tightly around the motor as this will placea strain on the cable and considerably shorten its life.W Connection of power cords 82/83/625/626The short cords from the junction box are connected to themotors. The long cord from the junction box is plugged intothe wall socket.The motors start and stop when the switches are operated.NoteThe motors must run simultaneously to ensure maximumsuction power. The motors should always be switched on andoff individually.Power cord All ModelsAvoid any damage which may be caused by running over,jamming, or pulling the power cord. When replacing the powercord make sure that an approved cord of the same type asthe original is used.Thermal cut-out protection (USA and Canadaonly - All Models)The vacuum motor is provided with a thermal cut-outprotection mechanism. This prevents the motor fromoverheating should a blockage occur.Remove the cause of the blockage to allow free air passage.When the motor is cool, it will automatically start again.E Diffuser All ModelThe diffuser is easily replaceable.Detaching the handle➀ Turn the two screws with a coin until their slots are vertical.➁ Release the handle by a gentle downward pressure at itscenter. Press until both ends spring out from the motorrecess. Lift off the exhaust grill and the diffuser. The soundabsorbent material must remain on top of the motor.➂ Remove the diffuser and mount the replacement.Replace the grill.Replacing the handlePlace the handle into position and lock it by turning thescrews until their slots are horizontal.Hose and tubes All modelR Hose connectionInsert the bayonet coupling in the suction inlet, and lock it inplace by turning it clockwise.Reverse this procedure to disconnect the hose.T Plastic hose and plastic tube➀ Fitting hose to the curved tube. Slide the hose into thecurved tube and adjust by turning until locking levers gripinto position.➁ Removing hose from curved tube. You may wish to removethe hose from the curved tube so that you can easilyremove a blockage.Push one of the locking levers with a screwdriver, asillustrated. Tip the locking lever until it is released. Repeat onthe other locking lever. The curved tube can now be separatedfrom the hose.Y Suction power regulation on curved plastic tube➀ The suction power of the nozzle can be regulated by theslide valve on the curved tube. Suction is most powerfulwhen the valve is pushed forward to close the inlet.➁ For cleaning of e.g. loose covers and curtains, the suctionpower can be reduced by sliding the valve backwards.U Rubber or plastic hose with curved steel tubeIf the hose or curved tube is blocked, the curved tube can bedetached from the hose to remove the obstruction.DismantlingHold the ring closest to the curved tube and pass it over thewand by simultaneously pulling and turning.AssemblingThe rubber coupling makes work easier and prolongs the lifeof the hose. (If the coupling becomes tight, it should beremoved and sprinkled liberally inside with French Chalk ortalcum powder).➀ Place rubber coupling on a flat surface and press one ringover the rim until it fits into the groove of the rubber muff.➁ Push curved tube through the joint and pull it through as far23
