Safety instructions (read carefully)
Every electrical device must be used for its particular function only, respecting the manufacturer’s
instructions. Failure to adhere to the instructions could result in serious person injury, electric shock, fire
or explosion.
The nowadays machines are normally produced according to the accident prevention regulations and
are often homologated by qualified institutes for the safety, but nobody and nothing can save
irresponsible users from danger.
Please, read carefully the following points and be sure to understand everything before using the
machines. The following information signals potentially dangerous conditions to the operator or
equipment.
WARNING: Fire or Explosion Hazard.
Do not spray water near electrical outlets.
Do not use the machine to spray or to suck dust, corrosive liquids (acids or bases) and explosive or
inflammable liquids.
Do not use the machine in an explosive atmosphere. This machine is not equipped with an explosion
proof motor. The electric motor will spark when powered on which could cause a flash fire or
explosion if machine is used in an area where flammable vapors/liquids or combustible dusts are
present.
Never use flammable liquids or operate machine in or near flammable liquids, vapors or combustible
dusts.
WARNING: Electrical Hazard.
Before putting the machine’s plug in the current socket, check that the voltage available is the same
indicated on the label of the machines.
Be sure that the electrical system is well earthed and that it has a safety differential switch.
Verify that the cable plug is complying with the outlet.
Do not modify plug.
Do not use adapters or multiple sockets, without knowing the electrical input of each user.
If any electrical extension is used, check that it corresponds to the absorbed power of the machine
and that the connection of the plug with the socket is complying and sealed.
Take care of the electrical cable. It must be integral and protected from water, tears and chemical
agents. Do not repair the cable in case of tears, but replace it with a new one. The cable must be
replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a
hazard.
Do not pull the cable to drag the machine or to pull the plug out.
Pull the plug out only when the machine is switched off.
Do not handle the plug with wet hands.

Unplug cable before servicing machine.
FOR SAFETY:
Do not let the machine being used by children and people unable to understand the danger
connected with the use of electrical power.
Do not bring the end of the suction hose or one of the accessories near your face or others’,
particularly near ears and eyes: the sucked air could seriously damage them.
If the machine is used as a wet vacuum cleaner, you must check the level of water in the recovery
tank, in order to prevent water from being sucked by the vacuum motor.
If the chemical you are using produces foam, or if you are cleaning carpet previously treated with
shampoo, you must put some antifoaming liquid into the recovery tank. In the long run, the foam
sucked by the motor can damage it.
In case of abnormal working (very noisy motor, not running pump, extreme temperature rise, or other
suspicious signals) switch off the machine and pull the plug out.
If foam or liquid escapes from the machine, switch machine off immediately.
After using, store the machine, well cleaned, in a cool and dry place.
The manufacturer cannot be held responsible for any damage/injury caused to persons or property,
because of the incorrect use of the machine due to procedures being used which are not specified in this
instruction manual.
Attention: all the electrical repairs must be performed by qualified personal only!
PROTECT THE ENVIRONMENT
Please dispose of packaging materials and old machine components in a safe environmentally
way according to your local waster disposal regulations.
Always remember to recycle.

Preparation for Work as a self-contained machine for carpet
1. Fill in the lower tank (solution tank) with cold or warm water, through the filling hole, adding a 5%
of not-foaming detergent (1/2 liter each 10 liters). If the machine is equipped with the optional
SMARTKIT, it is possible to put in the tank just clean water and keep separate the chemical
bottle. See the specific manual for more details.
Attention: wool carpet must be washed with cold water only!
2. Insert the plug of the cable into a wall socket (see Safety Regulations).
3. Set to position "I" the switches of the vacuum motor, the pump and the rotating brush.
4. Set the spray selector to maintenance cleaning ( ) or deep cleaning position ( ).
5. Adjust the pressure of the brush, acting on the brush adjustment lever.

6. To spray water, rotate backwards the RIGHT handle.
7. Pull back the machine. In this way you will clean a stripe of carpet by spraying, brushing and
vacuuming it in the same time.
8. After cleaning a complete stripe, stop spraying and proceed few more centimeters backwards, to
completely dry the stripe.
9. To put the machine at the beginning of the next stripe, bend the machine backwards, raising the
vacuum head, and push forward the machine.
10. Let the vacuum head touch again the carpet,
ATTENTION:
The brush motor is protected from overload, by a protection located on the control panel. If this
protection intervenes, it is necessary to reduce the pressure of the brush, to avoid the overload of the
motor. If this is not enough to avoid that the protection repeatedly intervenes, you should contact the
technical assistance. The repeated intervening of the protection might result in faults which cannot be
covered by warranty.
Keep an adequate safety distance from other people, who could be run over by the machine. Pay
attention to any object that could be hit by the machine. Never leave the machine unguarded.
Do not let the pump function without water! This could cause a damage of the pump.
The machine should not be used to vacuum dust, which would be sucked by the vacuum motor,
damaging it.
Verify that the brush inserted in the machine is the appropriate type for the surface to be cleaned. In
particular, the optional specific brush for hard floor should not be used on carpet, since it might be too
aggressive for carpet and damage it, or it could cause an overload of the brush motor.

Use with Accessories
In this modality the machine works as a box extractor. After filling the tanks with solution and inserting
the plug in the wall outlet (see steps 1 and 2 of the paragraph Preparation for Work as a self contained
machine for carpet), you need to do the following:
1. Connect the machine to the wand or to the hand-tool using the dedicated vacuum hose and solution
hose. The vacuum hose must be connected to the recovery tank cover, replacing the hose going to
the vacuum head. The solution hose must be connected to the specific female coupling, replacing the
hose going to the spray nozzles.
2. Switch on the vacuum motor by setting their switch to position "I", and the pump by setting the
switches to position "II". In this way the solution pump always works and it is not necessary to keep
pressed the control lever situated on the control panel.
3. To spray water you need to press the lever situated on the handle of the accessory.
Working Method
As regards the use as a self-contained machine, considering a rectangular surface, we suggest you to
proceed in parallel stripes, spraying and sucking the solution at the same time. Proceed at a speed
suitable to the dirt of the carpet. Act on the regulation valve to set the proper quantity of water to be
sprayed on the carpet.
In case of persistent spots, you can locally apply a pure detergent. On the market there are also spray
bottles with detergents which are specific for a particular kind of spot. Choose high-quality detergents
only, in order to avoid any damage to the surface. Always make a test in an area where an eventual
damage is less visible.

Maintenance
AVB9X is a professional machine. The warranty on these machine is of 1 year and regards the faults
due to manufacturing defects. The faults due to improper use are not covered by warranty. For further
details regarding warranty, contact the distributor supplying the machine.
For a good preservation and a long duration of the machine, observe the following advice:
1. After each use, before storing the machine, remove all the water from the solution and the recovery
tank. Put some liters of clean water into the solution tank and use the pump only, pressing the lever
of the solution valve. This operation is useful to clean the internal parts of the pump, of the couplings
and nozzles, removing the detergent residues.
2. After every use, store the machine in a cool and dry place with the cover open, to prevent humidity
inside the recovery tank from condensing on the internal parts of the vacuum motor, therefore
damaging it. The damage provoked by humidity that condenses on the motor (like the damage
caused by the foam sucked by the motor) is not covered by warranty.
3. Periodically clean the water filter, extracting it from the machine and rinsing it under current water.
4. Eliminate the lime that in time deposits inside the hydraulic circuit of the machine, by putting some
anti-lime solution in the solution tank and leave it for some hours. Then empty the tank and rinse. It is
enough to perform this operation every 6-8 months.
5. Periodically check and clean the filter of the vacuum motor, which is located under the transparent
circular cover of the upper tank.
6. Periodically check the consume of the carbon brushes of the vacuum motor. This check should be
done after 500 working hours.
7. Periodically check also the carbon brushes of the water pump, after 500 working hours.
8. Check the consume of the carbon brushes of the brush motor, after 1500 working hours.
9. Worn-out carbon brushes may result in a damage to vacuum motor or pump, which are not covered
by warranty. The check of carbon brushes should be done by technical assistance.
10. Periodically check that the brush rotates without problems, eliminating the causes which prevent a
free rotation. In case of difficulties, contact the technical assistance.
