2)
Remove the extension tube from the handgrip and attach the detergent spray kit (fig. 11),
operate the water clea- ner and spray the surface to be washed, starting from the bottom and
working upwards.
In the version with detergent suction, open the detergent tap (fig. 7B) and move the nozzle
forwards. Leave to work for a few minutes.
3)
Rinse the whole surface well from top to bottom with hot or cold water at high pressure.
4)
After use with detergent, rinse the high pressure water circuit by operating the pump for one
minute with the detergent tap completely closed.
MAINTENANCE
ONLY THE OPERATIONS AUTHORIZED IN THIS IN- STRUCTIONS MANUAL MAY BE
CARRIED OUT BY THE USER.
ALL OTHER OPERATIONS ARE FORBIDDEN.
Danger
For maintenance of the boiler, high pressure pump, the electrical parts and all parts with a safety
function, you must apply to our Technical service centre.
The manufacturer is not liable in case of tampering, changes, in-correct repairs or maintenance
carried out on the machine by a third person not provided with the manufacturer’s authorization.
All documents pertaining to the repair and planned service interventions, as well as any certificates
concerning the device installation according to the laws in force (in compliance with the provisions
of the IEC 60364-1 standard) must be kept carefully by the user, together with the Instructions
Manual.
Periodically, at least once a year, have the safety devices and the rated values checked at one of
our technical service centres.
Particularly, as for the hot water high pressure cleaner, which is factory set, the exhaust system
must be checked.
The rating done by the manufacturer determines a production of exhaust gases with a CO content
lower than 0,04% and a smoke content corresponding to a smoke point nr.2 Shell-Bacharach
according to the laws in force.
Danger
Disconnect the water cleaner from the mains electricity supply via the Solenoid switch or by
unplugging the plug from the socket and close the water supply tap (see chapters on connecting to
the electricity and water mains) before carrying out any maintenance jobs. To check to be able to
verify the plug is disconnected from the supply socket. Once maintenance has been completed,
ensure that the closing panels have been correctly reassembled and anchored with the screws
provided before reconnecting the cleaner to the mains.
Failure to do so may cause a risk of electric shock.
PRECAUTIONS AGAINST FROST
The cleaner must not be exposed to frost.
If the cleaner is left in premises where it is exposed to frost,
when work is over or for sto- rage, antifreeze must be used to
prevent serious damage to the hydraulic circuit.
OPERATIONS FOR USING ANTIFREEZE (fig. 12).
1) Turn off the water supply (tap), disconnect the hose and run the cleaner until it is completely
empty.
2) Stop the water cleaner with the ON/OFF switch in the “O” position.
3) Prepare a container with the solution of antifreeze.
4) Immerse the tube in the container with the anti-freeze solution.
5) Start the water cleaner with the ON/OFF switch in the “I” position.
6) Start the cleaner and let it run until antifreeze comes out through the lance.
7) Suck up antifreeze with the detergent intake system too.
8) Disconnect the water cleaner from the mains electricity supply via the Solenoid switch or by
