Nilfisk-ALTO MAXXI WD 3 Betriebsanleitung Seite 7

NOTE! Before dry material pick-up
These cleaners shall always have the sack fi lter and the fl oat
system mounted when picking up dry material.
This is also valid when using a dust bag.
NOTE! Before wet pick-up
Never use dust bag or sack fi lter when performing wet pick-up. The
machine is equipped with a fl oat system that shuts off the airfl ow through
the machine when the maximum liquid level is reached. Never pick up
liquid without the fl oat body in place.
To control: Loosen the two latches at each side of the motor top .Then re-
move the motor top. Check that the fl oat basket and fl oat valve are moun-
ted at the motor top. Remounting the motor top: Put back the motor top
to the container. Make sure that the switch/switches is located in direction
towards the suction inlet. Then tighten both latches so that the motor top
is properly secured. Always use a chemical defoamer when picking up
water containing foaming detergents. Use a defoamer recommended
by the detergent manufacturer.
1 Starting and operating the machine
Check that the electrical switch is switched off (in position 0). Then con-
nect the suction hose into the suction inlet at the machine by pushing the
hose forward until it is sliding in place at the inlet (to release the hose from
machine just twist and pull out the hose). Then connect the two tubes with
the hose handle, twist the tubes in order to ensure that they are properly
fi tted. Attach suitable nozzle to the tube. Choose nozzle depending on
what type of material that is to be picked-up. Connect the plug into a
proper electrical outlet. Put the electrical switch into position 1 in order to
start the motor. Some variants have two motors/fan units and two electrical
switches - one switch for each motor.
WD 7 & WD 7 Duo Adjusting the handle
The handle can be adjusted to the suitable working heigth. Start by
loosing the two locking screws at each side of the handle. Then adjust the
handle by moving it upwards or downwards until the proper angle is found.
Tighten the both locking screws again to secure the handle
Wet pick up
The machine is equipped with a fl oat body that shuts of the airfl ow through
the machine when the maximum liquid level is reached. You will then hear
a noticeable change of the sound from the motor and notice that the suc-
tion power decreases. When this occurs, switch the machine of. Discon-
nect the machine from the socket. See chapter 2 for emptying after wet
pick-up.
2 Emptying after wet pick-up
Before emptying the container, unplug the vacuum cleaner. Always
empty and clean the container and the fl oat system after picking-up
liquids. Never pick up liquid without the fl oat system installed in the
machine.

2f) Drain hose: Thease models have a draining hose that easy and com-
fortable drain the container from liquids. Detach the drain hose from the
bracket by pulling hose backwards from the cleaner. Place the drain hose
end near a fl oor drain and then remove the plug at hose end. The natural
pressure will then drain the liquids from the container.
2g) Emptying from the container: Pull the upper parts of the latches out-
wards and release the motor top. Remove the motor top. The suction hose
can be attached during emptying from the container. Grasp with one hand
at the handle at the lower part of the container. To avoid movement of the
trolley - place one foot at the basepart of the trolley. Then tilt the container
backwards and pour the liquids into a fl oor drain or similar.
2h) Wipe the fl oat valve and the fl oat basket with a damp cloth.
2i) Put back the motor top to the container. Make sure that the switch/
switches is located in direction towards the suction inlet. Secure with the
latches.
3 Emptying after dry pick-up
Remove the plug from the socket before emptying after dry pick-up.
Release the latches by pulling them outwards so that the motor top is re-
leased. Lift up the motor top from container. Check the fi lters and dustbag
regularly.
Cartridge fi lter: To clean the cartridge fi lter you can either shake, brush
or wash it. Wait until it is dry before you reuse it. A motor protection fi lter is
located in front of the motor inlet. Check this motor fi lter after dry pick-up
- replace to new fi lter if fi lter is clogged.
Sackfi lter:Grasp the sackfi lter and lift it up from cleaner. Shake fi lter so
that all dust is removed from the fi lter.
Dustbag: Check the bag regularly to ensure the fi ll factor. Never Replace
dust bag if necessary. Remove the old bag. The new bag is fi tted by pas-
sing the carboard piece with the rubber membrane through the
vacuum inlet. Make sure that the rubber membrane is passing past the
heightening at the vacuum inlet.
Motor fi lter: A fi lter is located in front of the motor inlet at the motor top.
Check this motor fi lter when emptying after dry cleaning - replace to new
fi lter if fi lter is clogged.
After emptying: Put back the motor top to the container. Make sure that
the switch/switches is located in direction towards the suction inlet. Secure
with the latches. Never pick up dry material without fi lter and dustbag fi tted
in the machine. The suction effi ciency of the vacuum cleaner depends on
the size and quality of the fi lter and dust bag. Therefore - use only Original
fi lter and dust bags.
4 Maintenance of the fl oat system
Remove the plug from the socket before performing maintenance.
Always empty and clean the container and the fl oat system after
picking-up liquids.
4a) Release the latch by pulling them outwards so that the motor top is
released. Lift up motor top from container. Turn the motor top to upside
down position.
4b) Then loosen the fl oat basket by turning the basket to the left. Remove
the complete fl oat system from motor top.
4c) A fi lter is located in front of the motor inlet. Check this motor fi lter
- replace to new fi lter if fi lter is clogged.
4d) Wipe the fl oat valve and fl oat basket with a damp cloth before the
motor top is reinstalled to the container. Then reinstall the fl oat valve to
the fl oat basket. Make sure that the sealed surface of the fl oat valve is
installed upwards in direction towards the motor top.
4e) To mount the fl oat basket - fi t the arrow at the basket to the arrow at
the motor top. Then secure the fl oat basket by turning it to the right.
