CARE AND MAINTENANCE
(vedi fig.
L
)
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 inta-
ke union periodically. This is important to prevent
fouling which may impair operation of the pump.
CHECKING THE SPRAY ROD NOZZLE
Replace the nozzle when the pressure drops
below the normal values.
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.
