NOTE!

The Sack Filter and the Float System should always be mounted in

the machine during both WET AND DRY operations.
Please also notice that the ﬁ ll factor at the container may vary when
using a sack ﬁ lter during wet pick-up operations.

NOTE! Before 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 remove the motor top. Check that the ﬂ oat basket and ﬂ oat

valve are mounted 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 tigh-

ten 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
connect 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 re-
lease 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 ad-
just 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 suction power decreases. When this occurs,
switch the machine of. Disconnect the machine from the socket.
See chapter 2 for emptying after wet pick-up.

Emptying: WD 7 & WD 7 Duo

2f) Drain hose: Thease models have a draining hose that easy
and comfortable 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 outwards and release the motor top. Remove the motor top.

Then remove the sack ﬁ lter from the container.
The suction hose can be attached during emptying from the con-

tainer. 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 released. 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 pro-
tection 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 passing 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 ef-
ﬁ 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.

5 After use

Remove the plug from the socket when machine is not in use.
Wind up the cord starting from the machine. The power cord can
be wound up around the handle/hook located on the motor top.
Some variants have special storage places for accessories.
