If the gas oil pump does not suck fuel, itwill damage and it will not allow the burnerto work. To check the correct rotation of themotor, it is necessary to check if air goes outfrom the chimney.FILLING UP WITH FUELFill the tank with the fuel indicated on the tech-nical data plate (Diesel, ref. 4).Avoid that the tank is empty when the machineis running in order not to damage the fuelpump.• Incorrect fuel shall not used as they asprovide hazard.Fill up the detergent tank with the suggestedproducts, suitable for the kind of washing to becarried out (ref. 5).• CAUTION: Make use only of liquid deter-gent, do not absolutely use acid or toomuch alkaline products. We suggest youto make use of our products, which havebeen studied for the use with washer ma-chines.START-UPSwitch on the machine by pressing the switch(ref. 1, pos.1) and leave it to run for a few min-utes to eliminate any dirt and air bubbles fromthe water circuit, then switch it off, connect thehigh pressure line to the spray gun (ref. 7) andfit the spray rod (ref. 8).
