5. Live conductors must not be vacuum cleaned by the
machine for dry dust before their current has been switch
off. This is to avoid creating a short-cut through the dust
remaining in the nozzles and tubes.
6. The machine must not be used for picking up combustible
or explosive materials, nor should it be used in an
explosive atmosphere.
7. Under no circumstances should the machine be used for
picking up hot material. In particular the machine must not
be used for cleaning open and closed fireplaces, ovens or
similar that contain warm or glowing ashes.
8. The machine must not be used if the electrical cord
shows any sign of damage. Regularly inspect the cord for
damage, in particular if it has been crushed, shut in a door
or run over.
9. The machine must not be used if it is faulty.
10. Do not unplug by pulling on cord. To unplug, grasp the
plug, not the cord.
11. Always turn off this appliance before connecting or
disconnecting motorised nozzle.
12. When repairing or replacing the cord, the same type of
cord as originally supplied with the machine must be
used. This cord can be supplied by NILFISK.
13. The plug must always be removed from the socket outlet
before starting any service work of the machine or the
cord.
14. Repair of the electrical unit with motor or the cord must
only be carried out by a skilled or instructed person after
having disconnected the main switch installed prior to the
machine or after having removed the plug from the current
socket.
15. No changes or modifications to the mechanical or
electrical safety devices should be made.
Instructions for use
Before using the machine make sure that the frequency and
voltage shown on the rating plate corresponds with the mains
voltage.
Specifications and details are subject to change without prior
notice.
On/off
Attaching the power cord 80P/90C
Place the appliance plug of the cord in the motor socket, only
80P. Pressing the button turns the motor on and off alternately.
Q Detaching the power cord 80P/90C
Do not roll the cord tightly around the motor as this will place
a strain on the cable and considerably shorten its life.
W Connection of power cords 82/83/625/626
The short cords from the junction box are connected to the
motors. The long cord from the junction box is plugged into
the wall socket.
The motors start and stop when the switches are operated.
Note
The motors must run simultaneously to ensure maximum
suction power. The motors should always be switched on and
off individually.
Power cord All Models
Avoid any damage which may be caused by running over,
jamming, or pulling the power cord. When replacing the power
cord make sure that an approved cord of the same type as
the original is used.
Thermal cut-out protection (USA and Canada
only - All Models)
The vacuum motor is provided with a thermal cut-out
protection mechanism. This prevents the motor from
overheating 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 Model
The diffuser is easily replaceable.
Detaching the handle
➀ Turn the two screws with a coin until their slots are vertical.
➁ Release the handle by a gentle downward pressure at its
center. Press until both ends spring out from the motor
recess. Lift off the exhaust grill and the diffuser. The sound
absorbent material
must remain on top of the motor.
➂ Remove the diffuser and mount the replacement.
Replace the grill.
Replacing the handle
Place the handle into position and lock it by turning the
screws until their slots are horizontal.
Hose and tubes All model
R Hose connection
Insert the bayonet coupling in the suction inlet, and lock it in
place by turning it clockwise.
Reverse this procedure to disconnect the hose.
T Plastic hose and plastic tube
➀ Fitting hose to the curved tube. Slide the hose into the
curved tube and adjust by turning until locking levers grip
into position.
➁ Removing hose from curved tube. You may wish to remove
the hose from the curved tube so that you can easily
remove a blockage.
Push one of the locking levers with a screwdriver, as
illustrated. Tip the locking lever until it is released. Repeat on
the other locking lever. The curved tube can now be separated
from the hose.
Y Suction power regulation on curved plastic tube
➀ The suction power of the nozzle can be regulated by the
slide valve on the curved tube. Suction is most powerful
when the valve is pushed forward to close the inlet.
➁ For cleaning of e.g. loose covers and curtains, the suction
power can be reduced by sliding the valve backwards.
U Rubber or plastic hose with curved steel tube
If the hose or curved tube is blocked, the curved tube can be
detached from the hose to remove the obstruction.
Dismantling
Hold the ring closest to the curved tube and pass it over the
wand by simultaneously pulling and turning.
Assembling
The rubber coupling makes work easier and prolongs the life
of the hose. (If the coupling becomes tight, it should be
removed and sprinkled liberally inside with French Chalk or
talcum powder).
➀ Place rubber coupling on a flat surface and press one ring
over the rim until it fits into the groove of the rubber muff.
➁ Push curved tube through the joint and pull it through as far
