   – “G 500 O Tens” manufactured by BUZIL, Germany.
   ● Close the filler hole of the cleaning liquid container with the cap.
   Before wet cleaning, the carpet, check the colorfastness of the cleaned carpet. Put a small amount of prepared solution on a white cloth and clean manually the carpet in at least a visible place.
   If the cloth is dyed, it means that the carpet colors are not permanent and the carpet cannot be cleaned using cleaning fluid G 500 O Tens.
   
5. Insert the cleaning liquid container (25) back to the previous position and press the container to fix it correctly (proceed in the reverse order as in case of removing the
   container).
6. Insert the container together with the water filter module (filtration unit and partition) into the vacuum cleaner.
   For protection against the formation of foam or at its the formation, when cleaning fill the rear container with an anti-foaming agent (31) recommended by the company Bosch, in the amounts specified on the label:
   – “G 478 Buz® Defoam” manufactured by the company BUZIL, Germany.
   ● Prepare the vacuum cleaner for operation according to section B.
   Use only the large or small atomizing nozzle for wet vacuum cleaning.
   ● The vacuum cleaner starts at the same power level it had been working before it was turned off. Set the desired power value (BWD420HYG, BWD421PET, BWD421PRO) by pressing the power adjustment buttons +/- (9).
7. Press the pump switch (7).
   The pump may only be switched on when the cleaning liquid container is filled with the solution of cleaning liquid and water. The lack of cleaning liquid manifests in a loud operation of the pump.
   If the nozzle does not atomize water although the pump is switched on, check if the following items are correctly installed: the cleaning liquid container (press the container), the fastening of the stub pipe in the valve in the base of the vacuum cleaner or the fastening of the hose end in the atomizing nozzle, check if the atomizing nozzle is not clogged.
8. Press the button to adjust the inflow of water to the nozzle on the hose handle.
   If you press the button in a pulsating manner, the water shall temporarily flow in a slower manner to the nozzle, if you press and slide the button backward, the water shall be continuously supplied to the nozzle.
   The handle is also equipped with a slider to adjust the suction power. Do not uncover this opening while picking up water or using the wet cleaning function.

Do not spray the cleaning liquid in one place on the carpet for too long in order not to soak the carpet.

• You should clean the carpet in such a way that during and immediately after cleaning nobody walks on the cleaned surface. After cleaning one part of the carpet stop the spraying process and dry the carpet by sliding the nozzle back and forth. Repeat until the whole surface of the carpet is dried.
• After ending the spraying process switch off the pump and press the button adjusting the water inflow to the nozzle for a moment to “release the pressure”.

The vacuum cleaner is equipped with a float which will automatically block the suction if the foam filter II (33) is heavily dirty or the liquid exceeds the maximum level. It is manifested by a pulsing limitation of the motor power and the lighting up of the clogged air inlet indicator (12) (BWD420HYG, BWD421PET, BWD421PRO).
In such a case switch off the vacuum cleaner by pressing the on/off button (8), unplug the appliance, clean the filter and empty the container.
Make sure the carpet is not soaked. It may lead to permanent deformation of the carpet (folding).

PICKING UP WATER
If you want to use the vacuum cleaner to vacuum liquid in the container, the vacuum cleaner should be prepared as in the case of vacuum cleaning with the use of the water filter module except that:

1. The container should be empty (without water).
2. You are to use atomizing nozzles (large or small), large atomizing nozzles with the gathering attachment, or the nozzle for picking up water.

Do not operate the vacuum cleaner with a full container! Do not vacuum large amounts of liquid at a time (e.g. with the hose immersed in water).

If the water exceeds the maximum level during vacuuming, the float will automatically block the suction. The maximum capacity of the container is about 5 l. In such a case proceed in the manner described above in the part concerning the blocking of suction caused by a dirty foam filter (pulsating motor speed).

END OF OPERATION CLEANING AND MAINTENANCE

• Switch off the vacuum cleaner by pressing the on/off button (8) and unplug the appliance.

TURBO BRUSH

Turbobrush description
Turbobrush is a suction nozzle with a rotating, turbine-driven brush. It is intended only for vacuum cleaners to clean carpets and fitted carpets. The plastic casing ensures an esthetic appearance. The rotating brush enables removing difficult rubbish, such as threads, rags, paper, etc. It is especially useful in houses with animals (cats, dogs), where removing fur from carpets is very burdensome. The brush roller is driven by a turbine placed in the joint, by means of belt transmission.
Proper position of the regulator ensures correct work of the turbo brush, depending on the height of carpet hair, and facilitates its movement along the carpet.

Safety instructions

When using the turbo brush observe the following safety precautions:

DANGER! / WARNING!
Failure to follow the safety instructions may result in injury

• Do not touch the rotating brush.
• Do not touch the power cords of electrical devices with the turbo brush. This may damage the insulation of these cords.
• Do not allow children near the working turbo brush.
• Touching the rotating brush may cause injury.
• This appliance can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning the use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Do not allow unsupervised children to clean and maintain the appliance.

Never use the turbo brush to:

• Polish floors.
• Suck:
• liquids,
• wet or damp dust,
• hot ash,
• burning objects, such as cigarettes, matches,
• sharp and hard items, such as razors, pins, thumbtacks, pieces of glass, etc.,

Assembling the turbo brush and the vacuum cleaner
Assemble the turbo brush and the vacuum cleaner according to the instruction manual.

Using the turbo brush

To avoid obstruction of rotating element remove big rubbish from the cleaned surface before cleaning.

• Switch the vacuum cleaner on.
• Set the regulator on the turbo brush body depending on the height of the carpet hair.
• Short hair carpet – move the regulator towards the sign .
• Long hair carpet – move the regulator towards the sign .

In order to use the vacuum cleaner with the turbo brush safely, especially while cleaning long hair carpets and animal skins, it is recommended to test the suction power of the turbo brush on a small area of the cleaned surface.
Do not hold the working turbo brush for a longer time in one place, but constantly move it, so as not to damage the carpet (fitted carpet).
While cleaning carpet fringes always move the turbo brush in the direction indicated by the arrow (Fig. K ). It prevents getting the fringes into the rotating brush.
The speed of the brush roller rotation depends on the amount of dust in the dust bag and the cleanliness of the filters. The roller may stop rotating on the carpet. Then the dust bag and filters should be replaced.

Maintenance and cleaning of the turbo brush

Before cleaning and maintenance of the turbo brush, it must be disassembled from the vacuum cleaner.

Cleaning of the rotating brush
During operation, the brush collects pieces of threads, strings, hair, rags, etc. They reduce cleaning efficiency.

To remove dirt from the rotating brush follow the steps below:

1. Place tips of scissors into the slot of the rotating brush.
2. Move the scissors so as to catch the threads and hair tangled on the brush.
3. Cut them and take them out manually or using small tongs. Be careful not to damage the bristle of the rotating brush.

Dirt such as matches, pieces of paper, or clothing may obstruct the suction duct of the turbo brush, leading to a significant reduction of the suction power and reduced speed or brush roller rotation (until it completely stops).

Cleaning of the suction duct of the turbo brush
To remove dirt from the suction duct of the turbo brush follow the steps below:

1. Turn the turbo brush with wheels upward.
2. Press the fastening in the turbine cover and take the cover out from the turbo brush.
3. Remove dirt from the suction duct, turbine blades, and turbine chamber.
4. Place the turbine cover so that its two ledges match the holes in the turbo brush body, and press the cover until it latches on the body. The characteristic clicking sound indicates the correct assembly of the turbine cover.

Cleaning the turbo brush
Never clean the turbo brush with gasoline, solvents, oils, and other chemicals that may cause discoloring of the housing.
Do not use granular cleaning agents that may scratch the housing.

• The turbo brush may be cleaned with a damp cloth (possibly moisten with a washing-up liquid).

Store the turbo brush away from hot ovens, radiators, heaters, etc. High temperature may lead to permanent deformation of the turbo brush housing.

The manufacturer does not accept any liability for any damages resulting from unintended use or inappropriate handling.
The manufacturer reserves his right for modifying the product at any time in order to adjust it to law regulations, norms, directives, or due to construction, trade aesthetic, or other reasons, without notifying it in advance.
