IMPORTANT: Before doing any work on the cleaner, discharge the pressure and disconnect the electricity and water supplies.

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 intake union periodically. This is important to prevent fouling, which may impair the 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 hardness of the water. Pour one litre of product for every 15 litres of water into a drum containing at least 30 litres of water. Disconnect the gun from the high-pressure line and place its free end in the drum in order to form a closed circuit, 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 returned 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 descaling product may cause wear of components. Comply with the regulations in force when disposing of the descaling agent.

Liquid softener tank integrated (optional, if included):

The descaling procedure must be carried out periodically with specific products. The interval depends on the hardness of the water. This operation should be carried out by our after-sales service, since the descaling product may cause wear of components. Comply with the regulations in force when disposing of the descaling agent.

• Fill the softener tank with our products (in all cases, with non-corrosive products). The dispensing rate is set at a medium value; the After Sales Services will be able to adapt the setting to local conditions.
