• In case of doubt, contact a Skilled Technician .
• Do not supply the high-pressure cleaner with water at a temperature in excess of 50°C/122°F or below
5°C/41°F.
• The pressure of the water supply must not be in excess of 8 bar/116 psi.
• Do not operate the high pressure cleaner with a priming depth in excess of 1.5m / 4.9 ft.
• Do not operate the high pressure cleaner if it is not connected to a water supply.
• Do not supply the high pressure cleaner with salt water or water containing impurities. In this event,
run the high pressure cleaner for a few minutes with clean water.
WARNING
• Follow current regulations for connection to the mains water supply in the country where the high-pressure
cleaner is installed.
4.3 Controls and connection to the mains electricity supply
WARNING
• A
Skilled Technician
must check that the electrical supply complies with the data indicated on the
identification label on the high pressure cleaner (see Fig. 4). It is especially important that the supply
voltage does not differ more than ± 5% from that indicated on the label.
• All connections to mains electricity must be carried out by a Qualified Eletrician according to IEC 60364-1
regulations or the equivalent standard in the country where the high pressure cleaner is to be used. It is
especially important that the current outlet where the high pressure cleaner is connected is provided with
an earth conductor and a suitable fuse (according to the size indicated on the identification label and
in the table of technical specifications), and must be protected by a magneto-thermal differential circuit
breaker, whose sensitivity is not in excess of 30 mA.
• If the power supply cable is too short, an extension cord can be used provided it is not longer than
10 m / 32.8 ft, the section of the wires is at least 2.5mm+ and the plug and the socket are waterproof.
Contact a
Qualified Eletrician
so that all these requirements are followed.
The use of unsuitable extension cords can be dangerous.
5 Operation
WARNING
• The high pressure cleaner must be used with care and attention. It is your responsibility to make sure
that any infrequent users have read these instructions and are acquainted with the operation of the high-
pressure cleaner; otherwise do not allow others to use the high pressure cleaner. High-pressure cleaners
must not be used by children or by unauthorised personnel.
• Comply with the safety warnings in the operating and maintenance instructions of any optional accessories
to be used.
• Do not use the high pressure cleaner if:
- the power supply cable or other important parts such as the high pressure pipe, the safety devices, the
cleaner gun and the lance are damaged;
- the high pressure cleaner has been tipped over or has been bumped;
- there are obvious leaks of water.
In these circumstances, the high-pressure cleaner should be tested by a Skilled Technician .
• It is especially important to pay great attention when the high pressure cleaner is used in areas where
there are moving vehicles as these can crush or damage the power supply cable, the high pressure pipe,
the cleaner gun etc.
• During operation, never leave the high-pressure cleaner unattended and make sure it is out of children’s
reach. Pay particular attention when using it in kindergartens, nursing homes and old people’s homes,
as unsupervised children, elderly people and disabled people may be present in such places.
• Before using the high-pressure cleaner, make sure it is in a dry place and that it is in a flat and stable
position in order to avoid accidents and prevent it from falling over.
• Before moving the high-pressure cleaner, follow the instructions in the
“Switching off”
section.
• Before starting the high-pressure cleaner, put on clothing which guarantees adequate protection against
the possibility of incorrect manoeuvres of the jet of pressurised water. Do not operate the high-pressure
cleaner near people unless they are also wearing protective clothing.
• High-pressure jets of water can be dangerous if they are not used properly. Do not point the jet in the
direction of people, animals, and energized electrical appliances or towards the high-pressure cleaner itself.
• Hold the cleaner gun firmly during use: when operating the lever (33), the operator is subjected to the
