• IT IS OBBLIGATORY TO WEAR PROTECTIVE GLOVES WHEN USING THE MACHINE.
• IT IS OBBLIGATORY TO WEAR PROTECTIVE GOGGLES WHEN USING THE MACHINE.

⚠️06WARNING: Do not direct the nozzle toward mechanical parts containing lubricant grease, as the grease will dissolve and spread over the surrounding ground. Vehicle tyres/tyre valves may only be cleaned from a minimum distance of 30 cm, otherwise the vehicle tyre/tyre valve could be damaged by the high-pressure jet. The first indication of this is a discoloration of the tyre. Damaged vehicle tyres/tyre valves can be deadly dangerous.

07WARNING: High pressure jets can be dangerous if subject to misuse. The jet must not be persons, animal, live electrical or the machine itself.

⚠08WARNING: High pressure hoses, fittings and couplings are important for the safety

⚠ 17WARNING: Children should be supervised to ensure that they do not play with the appliance.

⚠ 18WARNING: Never start this appliance without first completely unwinding the high-pressure hose.

⚠ 19WARNING: When winding and unwinding the pipe take care not to cause this appliance to overturn.

⚠️ 20WARNING: Before unwinding or winding the hose, switch the machine off and release the pressure in the hose itself (switching off).

⚠️21WARNING: Risk of explosion — Do not spray flammable liquids.

⚠️22WARNING: To ensure machine safety, use only original spare parts from the manufacturer or approved by the manufacturer.

⚠️23WARNING: Do not direct the jet against yourself or others in order to clean clothes or foot-wear.

⚠️24WARNING: High pressure cleaners shall not be used by children or untrained personnel.

⚠ WARNING: Water that has flown through backflow preventers is considered to be non-potable.

⚠️ XX WARNING: the machine shall be disconnected from its power source, by removing the plug from the socket-outlet, during cleaning or maintenance and when replacing spare parts

⚠️ XJ WARNING: If an extension cord is used, the plug and socket must be of watertight construction.

• Pump with a by-pass valve or stopping device.

> STABILITY

⚠ WARNING: The machine must be always kept on horizontal bases, in a safe and stable way.

> WATER SUPPLY

Water supply collection

Water supply from the water main

• Connect a supply hose (not included) to the water inlet of the unit and to the water supply.
• Open the water supply.

WARNING: (symbol) machine not suitable for connection to the potable water mains.

The cleaner can only be connected to the water mains if the water mains is separated by a backflow preventer. Make sure that the hose is at least ∅ 13mm-1/2 inch and that it is reinforced.

⚠ WARNING: Water that has flown through backflow preventers is considered to be nonpotable.

IMPORTANT: Only clean or filtered water should be used for intake. The delivery of the water intake tap should be equal to the double of the maximum pump range.

• Maximum intake water temperature: 40°C
• Max inlet water pressure: 1Mpa
  Place the machine as close to the water supply system as possible.

Failure to comply with the above conditions causes serious mechanical damage to the pump and the loss of warranty cover.

Water supply from the water tank build-in

- Switch off the unit.

⚠ WARNING: We recommend the use of demineralized water.

> ELECTRICITY SUPPLY

- The appliance's electrical connection must comply with the IEC 60364-1 standard.

IMPORTANT: Before connecting the appliance, make sure that the nameplate data are the same as those of the electrical mains and that the socket is protected by a differential security breaker with tripping sensitivity below 0.03 A - 30 ms.

- If the appliance's plug is not compatible with the socket, have the socket replaced with another of suitable type by professionally qualified staff.

- Never use the appliance in ambient temperatures below 0^ C if it is equipped with a PVC (H VV-F) cable.

⚠ XY WARNING: Inadequate extension cords can be dangerous.

⚠️XJ WARNING: If an extension cord is used, the plug and socket must be of watertight construction.

Information for supply may also be obtained from the plug manufacturer.

> POSITIONING OF THE CHIMNEY FOR INDOOR APPLICATION

(see fig. M)

⚠ WARNING: In case of operation indoors, adequate ventilation and gas venting must be assured.

Sometimes a chimney is necessary to remove the exhausts from the pressure cleaner.

This problem hasn't to be faced when the machine operates outdoor, but when it's installed indoor, the following recommendations must be followed:

- The chimney path must be always in ascent, straight vertical if possible, and preferably not exceeding a 5 m lenght.

- The exit of the chimney must be sheltered to avoid the dripping of rain and to allow the exhaust flow.

- The chimney section A must be 3 times the outlet chimney of the machine B and at distance of at least 20 cm.

It must be underlined that the above recommendations are extremely important to prevent the condensate from back dripping into the machine. The exausts contain sulphuric acid, condensating at a temperature of approximately 180°C. The condensation shall be avoid, but in any case the condensate from chimney shall not enter the machine.

The non observance of these recommendations may lead to the damage of the machine.

CHIMNEY SECTION: 3 times the area of chimney Chimney pipe diameter = 150 mm.

CHIMNEY SECTION FOR 2 BOILER: 6 times the area of chimney.

Chimney pipe diameter = 225 mm.

> INSTALLATION AND START-UP

IMPORTANT: The machine installation environment should be kept at between 10°C and 35°C.
