Use only as shown in this Manual. Only Nilsk-Advance recommended accessories must be used.
Take all necessary precautions to prevent hair, jewels and loose clothes from being caught by the machine
moving parts.
Do not leave the machine unattended without being sure that it cannot move independently.
Do not use the machine on slopes with a gradient exceeding the specications.
Do not use the machine in particularly dusty areas.
While using this machine, take care not to cause damage to people or objects.
Do not bump into shelves or scaffoldings, especially where there is a risk of falling objects.
Do not put any can containing uids on the machine.
The machine working temperature must be between +32°F and +104°F (0°C and +40°C).

The humidity must be between 30% and 95%.
Do not use the machine as a means of transport.
Do not use the machine on slopes with an inclination higher than 2%.
In case of re, use a powder re extinguisher, not a water one.
Do not tamper with the machine safety guards and follow the ordinary maintenance instructions scrupulously.
Do not allow any object to enter into the openings. Do not use the machine if the openings are clogged. Always
keep the openings free from dust, hairs and any other foreign material which could reduce the air ow.
Do not remove or modify the plates afxed to the machine.
If the machine is used according to the instructions, the vibrations are not dangerous. The machine vibration level
is less than 2.5 m/s2 (98/37/EEC-EN 1033/1995).
This machine cannot be used on roads or public streets.
Pay attention during machine transportation when temperature is below freezing point. The water in the recovery
tank or in the hoses could freeze and seriously damage the machine.
Use brushes and pads supplied with the machine and those specied in the User Manual. Using other brushes or
pads could reduce safety.
If parts must be replaced, require ORIGINAL spare parts from a Dealer or Authorised Retailer.
Carefully read all the instructions before performing any maintenance/repair procedure.
Do not wash the machine with direct or pressurised water jets, or with corrosive substances.

which are subject to standards that require disposal in special centres (see the User Manual).
Do not pull or carry the machine by the battery charger cable and never use the battery charger cable as a handle.
Do not close a door on the battery charger cable, or pull the battery charger cable around sharp edges or corners.
Do not run the machine on the battery charger cable.
Keep the battery charger cable away from heated surfaces.
Do not charge the batteries if the battery charger cable or the plug are damaged. If the machine is not working as
it should, has been damaged, left outdoors or dropped into water, return it to the Service Center.
Before using the battery charger, ensure that frequency and voltage values, indicated on the machine serial
number plate, match the electrical mains voltage.
Do not smoke while charging the batteries.
To reduce the risk of re, electric shock, or injury, do not leave the machine unattended when it is plugged in.
Before performing any maintenance procedure, disconnect the battery charger cable from the electrical mains.

supply hose (C) and clean it, especially in area of the vacuum end pipe (D). Install the supply hose (C).
Check that the plug vent hole (E) is not clogged, by driving in air and checking if it comes out from the outer hole (F). If
necessary clean the hole with compressed air. Install the plug (A).
Install the tank (45) and connect it to the hose (48).
When the detergent tank and the supply hose have been drained, the AXP must be drained too (see the procedure in the
following paragraph).
AXP DRAINING (For AdnityTM X 20 D - X 20 C - X 24 D)
Clean the detergent tank, then remove the detergent remained in the hoses and in the pump.
Grasp the handle (41) and carefully lower the tank (40).
Turn on the machine by turning the ignition key (80) to “I”.

Press the switches (77) and (82a) at the same time, until the switch warning light (78) starts ashing (after about 5
seconds).
Release the switches and wait for the warning light (78) to stop ashing and for the vacuum system to turn on.
Collect the detergent remained on the oor.
Turn the ignition key (80) to “0”.
Grasp the handle (41) and carefully lift the tank (40), then check that the hose (48) is empty, otherwise perform steps 3 to 9
again.
NOTE
The draining cycle lasts about 30 seconds, then the vacuum function automatically turns on, which allows to
remove the detergent remained.
The draining cycle can also be performed with the detergent tank (45) full of water, thus cleaning the system
thoroughly.
It is advisable to perform the draining cycle when the AXP is really dirty/encrusted because the machine has
not been used/cleaned for a long time.
The draining cycle can be performed also to quickly ll the detergent supply hose when the tank (45) is full
but the system is still empty.
If necessary, the draining cycle can be repeatedly performed.
