Depending on the job to be done, fit one of the two heads by inserting it into the lance hose and turning
it clockwise until it clicks securely onto the coupling. Now block it in place with the Securfix ring nut (11),
by turning it clockwise. Step I in Fig. 2.
To remove the head, turn the Securfix ring nut (11) anti-clockwise and remove it. Keep the head pressed
down into the lance hose housing and turn it anticlockwise until it is released, then remove it completely.
Step H in Fig. 2.
c) Unroll the high-pressure hose (23), connect the quick-fit connector (24) to the water outlet connector (8),
screw down and secure. Step C in Fig. 3.
d) Screw the end of the high pressure hose (23) (the end without the quick fit connector) onto the thread
of the spray gun (14) and secure it tightly using two 17 mm socket keys (not supplied). Step D in Fig. 3.
4.2 Checks and Connection to the Mains Water Supply
CAUTION
• The water supply must be able to guarantee the adequate delivery of water flow to the high pressure
cleaner; refer to the table of technical specifications.
In case of doubt, contact a Skilled Technician.
• Do not supply the water cleaner with water at a temperature in excess of 40°C/98°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 0 m/0 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 water cleaner
is installed.
4.3 Checks 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 (7) on the high pressure cleaner. 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 364
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 1,5mm² 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
