CHECKING THE PUMP OIL LEVEL

Check the oil level periodically. The oil must be changed for the first time after 50 working hours, with subsequent changes every 500 hours. SAE 20/30 , 15W-40, 20W-40 oil is recommended .

CHECKING THE WATER INTAKE FILTER

Inspect and clean the water intake filter on the inta- ke union periodically. This is important to prevent fouling which may impair operation of the pump.

CLEANING THE FUEL FILTER

Check the fuel filter periodically and replace if it has deteriorated or is excessively dirty. DESCALING The descaling procedure must be carried out periodically with specific products. The interval depends on the hard- ness of the water. Pour one litre of product for every 15 litres of water into a drum containing at least 30 litres of

22water. Disconnect the gun from the high pressure line and place its free end in the drum, in order to form a closed cir- cuit, and draw the solution into the machine for at least 10 minutes. The delivery end of the line should discharge into a canvas or mesh bag so that the scale removed is not re- turned to the circuit. Then restore the normal connection and rinse with plenty of cold water. This operation should be carried out by our after-sales service, since the descal- ing product may cause wear of components. Comply with the regulations in force when disposing of the descaling agent. BOILER CLEANING
