MAINTENANCE

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 fi rst time after 50 working
hours, with subsequent changes every 500
hours. Use oil SAE 20/30 (750 gr).
CHECKING THE WATER INTAKE FILTER
Inspect and clean the water intake fi lter (ref. 9)
on the intake union periodically. This is impor-
tant to prevent fouling which may impair op-
eration of the pump.
REPLACING THE SPRAY ROD NOZZLE
Replace the nozzle when the pressure drops
below the normal values.
ELECTRIC MOTOR
If the motor malfunctions, it cuts out. Wait 5-10
minutes before restarting. If the problem per-
sists, refer to the "TROUBLESHOOTING" section.
If you are still unable to eliminate the problem,
stop using the machine and contact an Author-
ized Service Centre.

WARNING: Take care not damage the elec-
tric cable. Have a damaged power cord re-
placed immediately by an authorized serv-
