CARE AND MAINTENANCE

(vedi fig. 

L

)

SCHEDULED MAINTENANCE PLAN

Visit www.lavorservice.com website and 

download the scheduled maintenance plan.

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 chan-

ged 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 in-

take 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 

water. 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.

Liquid softener tank integrated 

(Optional - if included)

The descaling procedure must be carried out pe-

riodically with specific products. The interval de-

pends on the hardness of the water. This opera-

tion should be carried out by our after-sales serv-

ice, 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.
